Oceania

Oceania

Oceania is a geographical (often geopolitical) region consisting of numerous countries and territories – mostly islands – in the Pacific Ocean. The exact scope of Oceania is controversial, with varying interpretations including East Timor, Australia, New Zealand, or none of these. For the oceans of the Earth, see Oceans.

Overview

The primary use of the term Oceania is to describe a continental region (like Europe or Africa) that lies between Asia and the Americas, with Australia as the major land mass. The name Oceania is used, rather than Australia, because unlike the other continental groupings, it is the ocean rather than the continent that links the nations together. Oceania is the smallest continental grouping in land area and the second smallest, after Antarctica, in population.

Countries and territories of Oceania

population Oceania has been traditionally divided into Micronesia, Melanesia and Polynesia (originally by the French explorer Dumont d'Urville in 1831). This subdivision is no longer recognised as correct by most geographers and scientists — who prefer to divide Oceania into Near Oceania and Remote Oceania — but it is still the most popular one. Most of Oceania consists of small island nations. Australia is the only continental country, and Papua New Guinea and East Timor are the only countries with land borders, both with Indonesia. The nations of Oceania have varying degrees of independence from their colonial powers and have negotiated a wide range of constitutional arrangements to suit their circumstances. The following list contains the countries and territories that are classified as part of Oceania by UNESCO; other countries are sometimes considered part of Oceania (see Other Interpretations below).

Other interpretations of Oceania

- Australia is sometimes not included in Oceania, although a term like Pacific islands would normally be used to describe Oceania without Australia
- Hawaii and the United States territories with no indigenous population in the North Pacific are sometimes included, but are normally grouped with the United States in North America. Hawaiians are a Polynesian race.
- Easter Island is a Polynesian island in the eastern Pacific Ocean, part of the territory of Chile, and is sometimes included in Oceania.
- On rare occasions the term may be stretched even further to include other Pacific island groups such as the Aleutian Islands.

Oceania in ecology

Oceania is one of eight terrestrial ecozones, which constitute the major ecological regions of the planet. The Oceania ecozone includes all of Micronesia, Fiji, and all of Polynesia except New Zealand. New Zealand, along with New Guinea and nearby islands, Australia, the Solomon Islands, Vanuatu, and New Caledonia, constitute the separate Australasia ecozone.

Population density

Geopolitics

Geopolitics analyses politics, history and social science with reference to geography. The term was coined by Rudolf Kjellén, a Swedish political geographer, at the end of the 19th century. Kjellén was inspired by the German geographer Friedrich Ratzel, who published his book "Politische Geographie" (political geography) in 1897. The term was popularized in English by US diplomat Robert Strausz-Hupé, a faculty member of the University of Pennsylvania. University of Pennsylvania The discipline gained attention largely through the work of Sir Halford Mackinder in England and his formulation of the Heartland Theory in 1904. This theory involved concepts diametrically opposed to the notion of Alfred Thayer Mahan about the significance of navies (he coined the term sea power) in world conflict. The Heartland theory, on the other hand, hypothesized the possibility for a huge empire to be brought into existence which didn't need to use coastal or transoceanic transport to supply its military industrial complex, and that this empire could not be defeated by all the rest of the world coalitioned against it. The basic notions of Mackinder's theory involve considering the geography of the Earth as being divided into a variation on the notion of the Old World (most of the Eastern Hemisphere) and the New World (the Western Hemisphere and what was called Oceania). The difference was that the archipelagoes which were traditionally able to defend themselves by naval power — historically, Britain and prospectively, Japan — were taken from the former, which was renamed the World Island. They were added to the other part of the world, renamed the Periphery, along with Philippines, Indonesia, Sri Lanka, and Madagascar. Australia and New Zealand were already part of the New World. Not only was the Periphery noticeably smaller than the World Island, it necessarily required much sea transport to function at the technological level of the World Island, which contained sufficient natural resources for a developed economy. Also, the industrial centers of the Periphery were necessarily located in widely-separated locations. The World Island could send its navy to destroy each one of them in turn. It could locate its own industries in a region further inland than the Periphery could, so they would have a longer struggle reaching them, and would be facing a well-stocked industrial bastion. This region Mackinder termed the Heartland. It was essentially comprised of Ukraine, Western Russia, and Mitteleuropa. The Heartland contained the grain reserves of Ukraine, and many other natural resources. Mackinder's notion of geopolitics can be summed up in his saying "Who rules East Europe commands the Heartland. Who rules the Heartland commands the World-Island. Who rules the World-Island commands the world." Though the theory was first imagined before World War I, developments in that war did not disprove it. Vast systems of trenches were not envisaged as part of the antagonism, but their appearance, as well as the demonstration that submarines could destroy convoys, made geopolitics appear even more frightening. The development of mechanized military transport needing petroleum fit right into the theory, for Russia's major oil reserves are located on the western shore of the Caspian Sea. Also, it was imagined before the industrial development of Russia herself. Thus it was as much a "thought experiment" as Schlieffen's plan to conquer France. Some influential Germans, both before and during the Third Reich, found this theory compatible with their desire to control Mitteleuropa and to take Ukraine. The intention to take the latter was indicated by the slogan Drang nach Osten, or "drive to the east". Although the fascists took much of Ukraine in World War II, nonetheless they were defeated. Another point which Mackinder missed was that the Soviets could actually move their factories out of the Heartland. For a time it seemed as though the theory was defunct, at first because conventional air force had been falsely touted as capable of destroying industries thousands of miles from the seacoast, and shortly afterward with the appearance of nuclear weapons. But with the coming of the Cold War, Mackinder's theory regained a bit of plausibility when instead of war, influence upon other nations was considered. This would be projection of power in other terms. The Soviet Union accomplished the domination of both Ukraine and Mitteleuropa. It was industrial, technically competent, and militarily able. Some anti-communists in the West who had heard of Mackinder gained additional fear of them from of his theory. What reduced the plausibility of this form of geopolitics drastically was the rise of Japan, a country without natural resources, yet which could surpass the Soviet Union without dealing with anything military at all. The Balance of terror, which enforced a state of relative peace during that period, also extends beyond the predictions of the original theory. Since then, the word geopolitics has been applied to other theories, most notably the notion of the clash of civilizations. In a peaceable world, neither sea lanes nor surface transport are threatened; hence all countries are effectively close enough from one another physically. It is in the realm of the political ideas and workings that there are differences, and the term has shifted to this arena. After World War I, Kjellen's thoughts and the term were picked up and extended by a number of scientists: in Germany by Karl Haushofer, Erich Obst, Hermann Lautensach and Otto Maull; in England, Mackinder and Fairgrieve; in France Vidal de la Blache and Vallaux. In 1923 Karl Haushofer founded the "Zeitschrift für Geopolitik" (magazine for geopolitics), which developed as a propaganda organ for Nazi-Germany.

In the abstract, geopolitics traditionally indicates the links and causal relationships between political power and geographic space; in concrete terms it is often seen as a body of thought assaying specific strategic prescriptions based on the relative importance of land power and sea power in world history. . . . The geopolitical tradition had some consistent concerns, like the geopolitical correlates of power in world politics, the identification of international core areas, and the relationships between naval and terrestrial capabilities.—Oyvind Osterud, The Uses and Abuses of Geopolitics, Journal of Peace Research, no. 2, 1988, p. 191

Pacific Ocean

:For other meanings of Pacific, see Pacific (disambiguation). The Pacific Ocean (from the Latin name Mare Pacificum, "peaceful sea", bestowed upon it by the Portuguese explorer Ferdinand Magellan) is the world's largest body of water. It encompasses a third of the Earth's surface, having an area of 179.7 million km² (69.4 million sq miles). Extending approximately 15,500 km (9,600 miles) from the Bering Sea in the Arctic to the icy margins of Antarctica's Ross Sea in the south (although the Antarctic regions of the Pacific are sometimes described as part of the circumpolar Southern Ocean)the Pacific reaches its greatest east-west width at about 5°N latitude, where it stretches approximately 19,800 km (12,300 miles) from Indonesia to the coast of Colombia. The western limit of the ocean is often placed at the Strait of Malacca. The lowest point on earth—the Mariana Trench—lies some 10,911 m (35,797 ft) below sea level. The Pacific contains about 25,000 islands (more than the total number in the rest of the world's oceans combined), the majority of which are found south of the equator. (See: Pacific Islands.) Along the Pacific Ocean's irregular western margins lie many seas, the largest of which are the Celebes Sea, Coral Sea, East China Sea, Sea of Japan, South China Sea, Sulu Sea, Tasman Sea, and Yellow Sea. The Straits of Malacca joins the Pacific and the Indian Oceans on the west, and the Straits of Magellan links the Pacific with the Atlantic Ocean on the east. As the Pacific straddles the ±180° longitude where East becomes West, the Asian side of the ocean (where latitudes are E) is correctly referred to as East Pacific and the opposite side (eastwards) where latitudes are W is the West Pacific. To retain the popular "left is western" and "right is eastern" means of reference, the Western Pacific is thus the East Pacific and the Eastern Pacific the West Pacific. The International Date Line follows the ±180° longitude to the greater part of its North-South demarcation but veers far eastwards around Kiribati (Caroline Island, which, not coincidentally, was renamed Millennium Island) and westwards round the Aleutian Islands as can be seen on the map at International Date Line. For most of Ferdinand Magellan's voyage from the Straits of Magellan to the Philippines, the Portuguese explorer indeed found the ocean peaceful. However, the Pacific is not always peaceful. Many typhoons and hurricanes batter the islands of the Pacific and the lands around the Pacific rim are full of volcanoes and often rocked by earthquakes. Tsunamis, caused by underwater earthquakes, have devastated many islands and wiped out whole towns. Tsunami

Ocean bottom

The ocean floor of the central Pacific basin is relatively uniform, an abyssal plain with a mean depth of about 4270 m (14,000 ft). The major irregularities in the basin are the extremely steep-sided, flat-topped submarine peaks known as seamounts. The western part of the floor consists of mountain arcs that rise above the sea as island groups, such as the Solomon Islands and New Zealand, and deep oceanic trenches, such as the Mariana Trench, the Philippine Trench, and the Tonga Trench. Most of the trenches lie adjacent to the outer margins of the wide western Pacific continental shelf. Along the eastern margin of the Pacific Basin is the East Pacific Rise, which is a part of the worldwide mid-oceanic ridge. About 3000 km (1800 miles) across, the rise stands about 3 km (2 miles) above the adjacent ocean floor. Because a relatively small land area drains into the Pacific, and because of the ocean's immense size, most sediments are authigenic or pelagic in origin. Authigenic sediments include montmorillonite and phillipsite. Pelagic sediments derived from seawater include pelagic red clays and the skeletal remains of sea life. Terrigenous sediments eroded from land masses are confined to narrow marginal bands close to land.

Elevation extremes

- lowest point: -10,924 m (-35,840 ft). at the bottom of the Mariana Trench
- highest point: 0 m (0 ft), sea level.

Water characteristics

Water temperatures in the Pacific vary from freezing in the poleward areas to about 29°C (84°F) near the equator. Salinity also varies latitudinally. Water near the equator is less salty than that found in the mid-latitudes because of abundant equatorial precipitation throughout the year. Poleward of the temperate latitudes salinity is also low, because little evaporation of seawater takes place in these frigid areas. The surface circulation of Pacific waters is generally clockwise in the Northern Hemisphere (the North Pacific Gyre) and anti-clockwise in the Southern Hemisphere. The North Equatorial Current, driven westward along latitude 15°N by the trade winds, turns north near the Philippines to become the warm Japan or Kuroshio Current. Turning eastward at about 45°N, the Kuroshio forks and some waters move northward as the Aleutian Current, while the rest turn southward to rejoin the North Equatorial Current. The Aleutian Current branches as it approaches North America and forms the base of an anti-clockwise circulation in the Bering Sea. Its southern arm becomes the chilled slow, south-flowing California Current. The South Equatorial Current, flowing west along the equator, swings southward east of New Guinea, turns east at about 50°S, and joins the main westerly circulation of the Southern Pacific, which includes the Earth-circling Antarctic Circumpolar Current. As it approaches the Chilean coast, the South Equatorial Current divides; one branch flows around Cape Horn and the other turns north to form the Peru or Humboldt Current.

Climate

Only the interiors of the large land masses of Australia, New Guinea, and New Zealand escape the pervasive climatic influence of the Pacific. Within the area of the Pacific, five distinctively different climatic regions exist: the mid-latitude westerlies, the trades, the monsoon region, the typhoon region, and the doldrums. Mid-latitude westerly air streams occur in both northerly and southerly latitudes, bringing marked seasonal differences in temperature. Closer to the equator, where most of the islands lie, steadily blowing trade winds allow for relatively constant temperatures throughout the year of 21-27°C (70-81°F). The monsoon region lies in the far western Pacific between Japan and Australia. Characteristic of this climatic region are winds that blow from the continental interior to the ocean in winter and in the opposite direction in summer. Consequently, a marked seasonality of cloudiness and rainfall occurs. Typhoons often cause extensive damage in the west and southwest Pacific. The greatest typhoon frequency exists within the triangle from southern Japan to the central Philippines to eastern Micronesia. Although more poorly defined than the other climatic regions, two major doldrum areas lie within the ocean, one located off the western shores of Central America and the other within the equatorial waters of the western Pacific. Both areas are noted for their high humidity, considerable cloudiness, light fluctuating winds, and frequent calms.

Geology

The Andesite Line is the most significant regional distinction in the Pacific. It separates the deeper, basic igneous rock of the Central Pacific Basin from the partially submerged continental areas of acidic igneous rock on its margins. The Andesite Line follows the western edge of the islands off California and passes south of the Aleutian arc, along the eastern edge of the Kamchatka Peninsula, the Kuril Islands, Japan, the Mariana Islands, the Solomon Islands, and New Zealand. The dissimilarity continues northeastward along the western edge of the Albatross Cordillera along South America to Mexico, returning then to the islands off California. Indonesia, the Philippines, Japan, New Guinea, and New Zealand—all eastward extensions of the continental blocks of Australia and Asia—lie outside the Andesite Line. Within the closed loop of the Andesite Line are most of the deep troughs, submerged volcanic mountains, and oceanic volcanic islands that characterize the Central Pacific Basin. It is here that basaltic lavas gently flow out of rifts to build huge dome-shaped volcanic mountains whose eroded summits form island arcs, chains, and clusters. Outside the Andesite Line, volcanism is of the explosive type, and the Pacific Ring of Fire is the world's foremost belt of explosive volcanism.

Landmasses

The largest landmass entirely within the Pacific Ocean is the island of New Guinea— the second largest in the world. Almost all of the smaller islands of the Pacific lie between 30°N and 30°S, extending from South-east Asia to Easter Island; the rest of the Pacific Basin is almost entirely submerged. The great triangle of Polynesia, connecting Hawaii, Easter Island, and New Zealand, encompasses the island arcs and clusters of the Cook, Marquesas, Samoa, Society, Tokelau, Tonga, and Tuamotu islands. North of the equator and west of the international date line are the numerous small islands of Micronesia, including the Caroline Islands, the Marshall Islands, and the Mariana Islands. In the southwestern corner of the Pacific lie the islands of Melanesia, dominated by New Guinea. Other important island groups of Melanesia include the Bismarck Archipelago, Fiji, New Caledonia, the Solomon Islands, and Vanuatu. Islands in the Pacific Ocean are of four basic types: continental islands, high islands, coral reefs, and uplifted coral platforms. Continental islands lie outside the Andesite Line and include New Guinea, the islands of New Zealand, and the Philippines. These islands are structurally associated with the nearby continents. High islands are of volcanic origin, and many contain active volcanoes. Among these are Bougainville, Hawaii, and the Solomon Islands. The third and fourth types of islands are both the result of coralline island building. Coral reefs are low-lying structures that have built up on basaltic lava flows under the ocean's surface. One of the most dramatic is the Great Barrier Reef off northeastern Australia. A second island type formed of coral is the uplifted coral platform, which is usually slightly larger than the low coral islands. Examples include Banaba (formerly Ocean Island) and Makatea in the Tuamotu group of French Polynesia.

History and economy

See the Oceania article for information on one set of the Pacific Island states listed below here. Important human migrations occurred in the Pacific in prehistoric times, most notably those of Polynesians from Tahiti to Hawaii and New Zealand. The ocean was sighted by Europeans early in the 16th century, first by Vasco Núñez de Balboa (1513) and then by Ferdinand Magellan, who crossed the Pacific during his circumnavigation (1519-1522). In 1564 conquistadors crossed the ocean from Mexico led by Miguel López de Legazpi who sailed to the Philippines and Mariana Islands. For the remainder of the 16th century Spanish influence was paramount, with ships sailing from Spain to the Philippines, New Guinea, and the Solomons. The Manila Galleons linked Manila and Acapulco. During the 17th century the Dutch, sailing around southern Africa, dominated discovery and trade; Abel Janszoon Tasman discovered (1642) Tasmania and New Zealand. The 18th century marked a burst of exploration by the Russians in Alaska and the Aleutian Islands, the French in Polynesia, and the British in the three voyages of James Cook (to the South Pacific and Australia, Hawaii, and the North American Pacific Northwest). Growing imperialism during the 19th century resulted in the occupation of much of Oceania by Great Britain and France, followed by the United States. Significant contributions to oceanographic knowledge were made by the voyages of the HMS Beagle in the 1830s, with Charles Darwin aboard; the HMS Challenger during the 1870s; the U.S.S. Tuscarora (1873-76); and the German Gazelle (1874-1876). Although the United States took the Philippines in 1898, Japan controlled the western Pacific by 1914, and occupied many other islands during World War II. By the end of that war the U.S. Pacific Fleet was the virtual master of the ocean. Seventeen independent states are located in the Pacific: Australia, Fiji, Japan, Kiribati, Marshall Islands, Micronesia, Nauru, New Zealand, Palau, Papua New Guinea, the Philippines, Samoa, Solomon Islands, Republic of China (Taiwan), Tonga, Tuvalu, and Vanuatu. Eleven of these nations have achieved full independence since 1960. The Northern Mariana Islands are self-governing with external affairs handled by the United States, and Cook Islands and Niue are in similar relationships with New Zealand. Also within the Pacific are the U.S. state of Hawaii and several island territories and possessions of Australia, Chile, Ecuador, France, Japan, New Zealand, the United Kingdom, and the United States. The exploitation of the Pacific's mineral wealth is hampered by the ocean's great depths. In shallow waters of the continental shelves off the coasts of Australia and New Zealand, petroleum and natural gas are extracted, and pearls are harvested along the coasts of Australia, Japan, Papua New Guinea, Nicaragua, Panama, and the Philippines, although in sharply declining volume. The Pacific's greatest asset is its fish. The shoreline waters of the continents and the more temperate islands yield herring, salmon, sardines, snapper, swordfish, and tuna, as well as shellfish. In 1986, the member nations of the South Pacific Forum declared the area a nuclear-free zone in an effort to halt nuclear testing and prevent the dumping of nuclear waste there.

Europe

:This article is about the continent. For other meanings, see Europe (disambiguation). Europe is geologically and geographically a peninsula or subcontinent, forming the westernmost part of Eurasia. It is conventionally considered a continent, which, in this case, is more of a cultural distinction than a geographic one. It is bounded to the north by the Arctic Ocean, to the west by the Atlantic Ocean and to the south by the Mediterranean and Black Seas and the Caucasus. Europe's boundary to the east is vague, but has traditionally been given as the Ural Mountains and Caspian Sea to the southeast: the Urals are considered by most to be a geographical and tectonic landmark separating Asia from Europe. :See also Continent, Bicontinental country, and Table of European territories and regions. Table of European territories and regions Table of European territories and regions Europe is the world's second-smallest continent in terms of area, covering around 10,790,000 km² (4,170,000 sq mi) or 2.1% of the Earth's surface, and is only larger than Australia. In terms of population, it is the third-largest continent (Asia and Africa are larger) with a population of more than 700,000,000, or about 11% of the world's population.

Etymology

Africa.]] In Greek mythology, Europa was a Phoenician princess who was abducted by Zeus in bull form and taken to the island of Crete, where she gave birth to Minos. For Homer, Europé (Greek: Ευρωπη; see also List of traditional Greek place names) was a mythological queen of Crete, not a geographical designation. Later Europa stood for mainland Greece, and by 500 BC its meaning had been extended to lands to the north. The Greek term Europe has been derived from Greek words meaning broad (eurys) and face (ops) -- broad having been an epitheton of Earth herself in the reconstructed Proto-Indo-European religion; see Prithvi (Plataia). A minority, however, suggest this Greek popular etymology is really based on a Semitic word such as the Akkadian erebu meaning "sunset" (see also Erebus). From the Middle Eastern vantagepoint, the sun does set over Europe, the lands to the west. Likewise, Asia is sometimes thought to have derived from the Akkadian word asu, meaning "sunrise", and is the land to the east from a Mesopotamian perspective.

History

Europe has a long history of cultural and economic achievement, starting as far back as the Palaeolithic, although this is true for the rest of the Old World as well. The recent discovery at Monte Poggiolo, Italy, of thousands of hand-shaped stones, tentatively carbon-dated to 800,000 years ago, may prove to be of particular importance. The origins of Western democratic and individualistic culture are often attributed to Ancient Greece, though numerous other distinct influences, in particular Christianity, can also be credited with the spread of concepts like egalitarianism and universality of law. The Roman Empire divided the continent along the Rhine and Danube for several centuries. Following the decline of the Roman Empire, Europe entered a long period of changes arising from what is known as the Age of Migrations. That period has been known as the "Dark Ages" to Renaissance thinkers. During this time, isolated monastic communities in Ireland and elsewhere carefully safeguarded and compiled written knowledge accumulated previously. The Renaissance and the New Monarchs marked the start of a period of discovery, exploration, and increase in scientific knowledge. In the 15th century Portugal opened the age of discoveries, soon followed by Spain. They were later joined by France, the Netherlands and the United Kingdom in building large colonial empires with vast holdings in Africa, the Americas, and Asia. After the age of discovery, the ideas of democracy took hold in Europe. Struggles for independence arose, most notably in France during the period known as the French Revolution. This led to vast upheaval in Europe as these revolutionary ideas propagated across the continent. The rise of democracy led to increased tensions within Europe on top of the tensions already existing due to competition within the New World. The most famous of these conflicts was when Napoleon Bonaparte rose to power and set out on a conquest, forming a new French empire that soon collapsed. After these conquests Europe stabilised, but the old foundations were already beginning to crumble. The Industrial Revolution started in the United Kingdom in the late 18th century, leading to a move away from agriculture, much greater general prosperity and a corresponding increase in population. Many of the states in Europe took their present form in the aftermath of World War I. From the end of World War II through the end of the Cold War, Europe was divided into two major political and economic blocks: Communist nations in Eastern Europe and capitalist countries in Western Europe. Around 1990, with the fall of the Berlin Wall, the Eastern bloc disintegrated.

Geography and extent

Eastern bloc Geographically Europe is a part of the larger landmass known as Eurasia. The continent begins at the Ural Mountains in Russia, which define Europe's eastern boundary with Asia. The southeast boundary with Asia isn't universally defined. Most commonly the Ural or, alternatively, the Emba river can serve as possible boundaries. The boundary continues with the Caspian Sea, and then the Araxes river in the Caucasus, and on to the Black Sea; the Bosporus, the Sea of Marmara, and the Dardanelles conclude the Asian boundary. The Mediterranean Sea to the south separates Europe from Africa. The western boundary is the Atlantic Ocean, but Iceland, much farther away than the nearest points of Africa and Asia, is also often included in Europe. There is ongoing debate on where the geographical centre of Europe is. At times "Europe" is defined with greater regard to political, economic, and other cultural considerations. This has led to there being several different Europes that are not always identical in size, including or excluding countries according to the definition of Europe used. Almost all European countries are members of the Council of Europe, the exceptions being Belarus, and the Holy See (Vatican City). The idea of the European continent is not held across all cultures. Some non-European geographical texts refer to the continent of Eurasia, or to the European peninsula, given that Europe is not surrounded by sea. In the past concepts such as Christendom were deemed more important. In another usage, Europe is increasingly being used as a short-form for the European Union (EU) and its members, currently consisting of 25 member states. A number of other European countries are negotiating for membership, and several more are expected to begin negotiations in the future (see Enlargement of the European Union).

Physical features

In terms of shape, Europe is a collection of connected peninsulas. The two largest of these are "mainland" Europe and Scandinavia to the north, divided from each other by the Baltic Sea. Three smaller peninsulas (Iberia, Italy and the Balkans) emerge from the southern margin of the mainland into the Mediterranean Sea, which separates Europe from Africa. Eastward, mainland Europe widens much like the mouth of a funnel, until the boundary with Asia is reached at the Ural Mountains. Land relief in Europe shows great variation within relatively small areas. The southern regions, however, are more mountainous, while moving north the terrain descends from the high Alps, Pyrenees and Carpathians, through hilly uplands, into broad, low northern plains, which are vast in the east. This extended lowland is known as the Great European Plain, and at its heart lies the North German Plain. An arc of uplands also exists along the northwestern seaboard, beginning in the western British Isles and continuing along the mountainous, fjord-cut spine of Norway. This description is simplified. Sub-regions such as Iberia and Italy contain their own complex features, as does mainland Europe itself, where the relief contains many plateaus, river valleys and basins that complicate the general trend. Iceland and the British Isles are special cases. The former is a land unto itself in the northern ocean which is counted as part of Europe, while the latter are upland areas that were once joined to the mainland until rising sea levels cut them off. Due to the few generalisations that can be made about the relief of Europe, it is less than surprising that its many separate regions provided homes for many separate nations throughout history.

Biodiversity

Having lived side-by-side with agricultural peoples for millennia, Europe's animals and plants have been profoundly affected by the presence and activities of man. With the exception of Scandinavia and northern Russia, few areas of untouched wilderness are today to be found in Europe, except for different natural parks. The main natural vegetation cover in Europe is forest. The conditions for growth are very favourable. In the north, the Gulf Stream and North Atlantic Drift warm the continent. Southern Europe could be described as having a warm, but mild climate. There are frequent summer droughts in this region. Mountain ridges also affect the conditions. Some of these (Alps, Pyrenees) are oriented east-west and allow the wind to carry large masses of water from the ocean in the interior. Others are oriented south-north (Scandinavian Mountains, Dinarides, Carpathians, Apennines) and because the rain falls primarily on the side of mountains that is oriented towards sea, forests grow well on this side, while on the other side, the conditions are much less favourable. Few corners of mainland Europe have not been grazed by livestock at some point in time, and the cutting down of the pre-agricultural forest habitat caused disruption to the original plant and animal ecosystems. Eighty to ninety per cent of Europe was once covered by forest. It stretched from the Mediterranean Sea to the Arctic Ocean. Though over half of Europe's original forests disappeared through the centuries of colonisation, Europe still has over one quarter of the world's forests - spruce forests of Scandinavia, vast pine forests in Russia, chestnut rainforests of the Caucasus and the cork oak forests in the Mediterranean. During recent times, deforestation has been stopped and many trees were planted. However, in many cases conifers have been preferred over original deciduous trees, because these grow quicker. The plantations and monocultures now cover vast areas of land and this offers very poor habitats for European forest dwelling species. The amount of original forests in Western Europe is just two to three per cent (in the European part of Russia five to ten per cent). The country with the smallest forest-covered area is Ireland (eight per cent), while the most forested country is Finland (72 per cent). In "mainland" Europe, deciduous forest prevails. The most important species are beech, birch and oak. In the north, where taiga grows, a very common tree species is the birch tree. In the Mediterranean, many olive trees have been planted, which are very well adapted to its arid climate. Another common species in Southern Europe is the cypress. Coniferous forests prevail at higher altitudes up to the forest boundary and as one moves north within Russia and Scandinavia, giving way to tundra as the Arctic is approached. The semi-arid Mediterranean region hosts much scrub forest. A narrow east-west tongue of Eurasian grassland—the steppe—extends eastwards from Ukraine and southern Russia and ends in Hungary and traverses into taiga to the north. Glaciation during the most recent ice age and the presence of man affected the distribution of European fauna. As for the animals, in many parts of Europe most large animals and top predator species have been hunted to extinction. The woolly mammoth and aurochs were extinct before the end of the Neolithic period. Today wolves (carnivores) and bears (omnivores) are endangered. Once they were found in most parts of Europe. However, deforestation caused these animals to withdraw further and further. By the Middle Ages the bears' habitats were limited to more or less inaccessible mountains with sufficient forest cover. Today, the brown bear lives primarily in the Balkan peninsula, in the North and in Russia; a small number also persist in other countries across Europe (Austria, Pyrenees etc.), but in these areas brown bear populations are fragmented and marginalised because of the destruction of their habitat. In the far North of Europe, polar bears can also be found. The wolf, the second largest predator in Europe after the brown bear, can be found primarily in Eastern Europe and in the Balkans. Other important European carnivores are Eurasian lynx, European wild cat, foxes (especially the red fox), jackal and different species of martens, hedgehogs, different species of snakes (vipers, grass snake...), different birds (owls, hawks and other birds of prey) Important European herbivores are snails, amphibians, fish, different birds, and mammals, like rodents, deers and roe deers, boars, and living in the mountains, marmots, steinbocks, chamoises among others. Sea creatures are also an important part of European flora and fauna. The sea flora is mainly phytoplankton. Important animals that live in European seas are zooplankton, molluscs, echinoderms, different crayfish, squids and octopuses, fish, dolphins, and whales. Some animals live in caves, for example proteus and bats.

Demographics

Almost all of Europe was possibly settled before or during the last ice age ca. 10,000 years ago. Neanderthal man and modern man coexisted during at least some of this time. Roman road building helped with the interbreeding of the native Europeans' genetics. In contemporary times Europe has one of the lowest inbreeding rates in the world because of an extensive transport network paired with open borders. Europe passed well over 600 million people before the turn of the 20th century, but now is entering a period of population decline, for a variety of social factors.

Linguistic and cultural regions

The sub-division in several linguistic and cultural regions is much less subjective than the geographical sub-division, since they correspond to people's cultural connections. There are three main groups:

Germanic Europe

Germanic Europe, where Germanic languages are spoken. This area corresponds more or less to north-western Europe and some parts of central Europe. The main religion of the region is Protestantism, even if there are also some countries with Catholic majority (particularly Austria). This region consists of: United Kingdom, Ireland, Iceland, Germany, Austria, Netherlands, Denmark, Sweden, Norway, Luxembourg, Liechtenstein, the Faroe Islands, German-speaking Switzerland, the Flemish part of Belgium, the Swedish-speaking municipalities of Finland, and the South Tyrol part of Italy.

Latin Europe

Latin Europe, where the Romance languages are spoken. This area corresponds more or less to south-western Europe, with the exception of Romania and Moldova which are situated in Eastern Europe. The major religion is Catholicism, except in Romania and Moldova. This area consists of: Italy, Spain, Portugal, France, Romania, Moldova, French-speaking Belgium and French speaking Switzerland, and Italian and Romansh speaking Switzerland as well.

Slavic Europe

Slavic Europe, where Slavic languages are spoken. This area corresponds, more or less, to Central and Eastern Europe. The main religions are Orthodox Christianity and Catholicism, with large Muslim populations in some parts formerly ruled by the Ottoman Empire. This area consists of: Belarus, Bosnia and Herzegovina, Bulgaria, Croatia, the Czech Republic, the Republic of Macedonia, Poland, Russia, Serbia and Montenegro, Slovakia, Slovenia and Ukraine.

Others

Outside of these three main groups we can find:
- The Celtic nations: Scotland, Wales, Northern Ireland, Cornwall (within the United Kingdom); the Isle of Man (a British Crown dependency); the Republic of Ireland; Brittany (within France). These are all nations where a Celtic language is spoken, or was spoken into modern times, and there is a degree of shared culture (see Pan Celticism). Also considered Celtic nations, by some, are both Galicia (Spain) and Asturias, (within Spain), whose own Celtic language died out several hundred years ago.
- Greece, the only country of "Hellenic Europe".In Hellenic Europe we can consider also the Greek Cypriot community It is sometimes associated with the Latin countries, due to the geographical and cultural ties to the Mediterranean Sea, and sometimes to the Slavic-Orthodox part of Europe due to the importance or Orthodoxy in Greece.
- Armenia has a language that constitutes a separate branch of Indo-European family of languages. The Armenian language is spoken in Armenia and other European countries with Armenian communities (such as France, Greece, Belgium, Russia, Germany etc.).
- Ibero-Caucasian, a group that includes ethnic groups throughout the Caucasus region (both North and South). Ibero-Caucasian languages are not linked to the Indo-European languages. This group includes Georgians, Abkhaz, Chechens, Balkars, and a number of other smaller ethnic groups that reside in the Caucasus.
- Turkey, having an Altaic language not of Indo-European origin, and mainly a Muslim country, unlike the main regions' different versions of Christianity.
- Hungary, having a language related to Finnish and Estonian. Due to its location Hungary is normally grouped with Central or Eastern European countries.
- Finland and Estonia, whose languages are related to Hungarian. Despite this connection (not a close one), Finland and Estonia are normally associated with northern European countries (of an even farther connection).

Australia

The Commonwealth of Australia is a country in the Southern Hemisphere comprising the world's smallest continent and a number of islands in the Southern, Indian and Pacific Oceans. Australia's neighbouring countries are Indonesia, East Timor and Papua New Guinea to the north, the Solomon Islands, Vanuatu and New Caledonia to the northeast, and New Zealand to the southeast. The continent of Australia has been inhabited for over 40,000 years by Indigenous Australians. After sporadic visits by fishermen from the north and by European explorers and merchants starting in the 17th century, the eastern half of the continent was claimed by the British in 1770 and officially settled as the penal colony of New South Wales on 26 January 1788. As the population grew and new areas were explored, another five largely self-governing Crown Colonies were successively established over the course of the 19th century. On 1 January 1901, the six colonies federated and the Commonwealth of Australia was formed. Since federation, Australia has maintained a stable liberal democratic political system and remains a Commonwealth Realm. The current population of around 20.4 million is concentrated mainly in the large coastal cities of Sydney, Melbourne, Brisbane, Perth and Adelaide.

Origin and history of the name

The name Australia is derived from the Latin australis, meaning southern. Legends of an "unknown southern land" (terra australis incognita) date back to the Roman times and were commonplace in mediæval geography, but they were not based on any actual knowledge of the continent. The Dutch adjectival form Australische ("Australian," in the sense of "southern") was used by Dutch officials in Batavia to refer to the newly discovered land to the south as early as 1638. The first English language writer to use the word "Australia" was Alexander Dalrymple in An Historical Collection of Voyages and Discoveries in the South Pacific Ocean, published in 1771. He used the term to refer to the entire South Pacific region, not specifically to the Australian continent. In 1793, George Shaw and Sir James Smith published Zoology and Botany of New Holland, in which they wrote of "the vast island, or rather continent, of Australia, Australasia or New Holland." New Holland was established on this site.]] The name "Australia" was popularised by the 1814 work A Voyage to Terra Australis by the navigator Matthew Flinders. Despite its title, which reflected the view of the Admiralty, Flinders used the word "Australia" in the book, which was widely read and gave the term general currency. Governor Lachlan Macquarie of New South Wales subsequently used the word in his dispatches to England. In 1817 he recommended that it be officially adopted. In 1824, the British Admiralty agreed that the continent should be known officially as Australia.

History

England, claiming the land for Britain in 1770. This replica was built in Fremantle in 1988 for Australia's bicentenary.]] The first human habitation of Australia is estimated to have occurred between 42,000 and 48,000 years ago. The first Australians were the ancestors of the current Indigenous Australians; they arrived via land bridges and short sea-crossings from present-day India or Southeast Asia. Most of these people were hunter-gatherers, with a complex oral culture and spiritual values based on reverence for the land and a belief in the Dreamtime. The Torres Strait Islanders, ethnically Melanesian, inhabited the Torres Strait Islands and parts of far-north Queensland; they possess distinct cultural practices and practised subsistence agriculture. The first undisputed recorded European sighting of the Australian continent was made by the Dutch navigator Willem Jansz, who sighted the coast of Cape York Peninsula in 1606. During the 17th century, the Dutch charted the whole of the western and northern coastlines of what they called New Holland, but made no attempt at settlement. In 1770, James Cook sailed along and mapped the east coast of Australia, which he named New South Wales and claimed for Britain. The expedition's discoveries provided impetus for the establishment of a penal colony there following the loss of the American colonies that had previously filled that role. penal colony was Australia's largest penal colony.]] The British Crown Colony of New South Wales started with the establishment of a settlement at Port Jackson by Captain Arthur Phillip on 26 January 1788. This date was later to become Australia's national day, Australia Day. Van Diemen's Land, now known as Tasmania, was settled in 1803 and became a separate colony in 1825. Britain formally claimed the western part of Australia in 1829. Separate colonies were created from parts of New South Wales: South Australia in 1836, Victoria in 1851, and Queensland in 1859. The Northern Territory (NT) was founded in 1863 as part of the Province of South Australia. Victoria and South Australia were founded as "free colonies"—that is, they were never penal colonies, although the former did receive some convicts from Tasmania. Western Australia was also founded "free", but later accepted transported convicts due to an acute labour shortage. The transportation of convicts to Australia was phased out between 1840 and 1868. The Indigenous Australian population, estimated at about 350,000 at the time of European settlement, declined steeply for 150 years following settlement, mainly because of infectious disease, and forced migration, the removal of children and other colonial government policies, that some historians and Indigenous Australians have argued could be considered to constitute genocide by today's understanding. Such interpretations of Aboriginal history are disputed by some as being exaggerated or fabricated for political or ideological reasons. Following the 1967 referendum, the Federal government gained the power to implement policies and make laws with respect to Aborigines. Traditional ownership of land—native title—was not recognised until the High Court case Mabo v Queensland (No 2) overturned the notion of Australia as terra nullius at the time of European occupation. terra nullius ceremony in Port Melbourne, Victoria, 25 April 2005. Ceremonies such as this are held in virtually every suburb and town in Australia.]] A gold rush began in Australia in the early 1850s, and the Eureka Stockade rebellion in 1854 was an early expression of nationalist sentiment. Between 1855 and 1890, the six colonies individually gained responsible government, managing most of their own affairs while remaining part of the British Empire. The Colonial Office in London retained control of some matters, notably foreign affairs, defence and international shipping. On 1 January 1901, federation of the colonies was achieved after a decade of planning, consultation and voting, and the Commonwealth of Australia was born, as a Dominion of the British Empire. The Australian Capital Territory (ACT) was formed from New South Wales in 1911 to provide a location for the proposed new federal capital of Canberra (Melbourne was the capital from 1901 to 1927). The Northern Territory was transferred from the control of the South Australian government to the Commonwealth in 1911. Australia willingly participated in World War I; many Australians regard the defeat of the Australian and New Zealand Army Corps (ANZACs) at Gallipoli as the birth of the nation—its first major military action. Much like Gallipoli the Kokoda Track Campaign is regarded by many as a nation defining battle from World War II. The Statute of Westminster 1931 formally ended most of the constitutional links between Australia and Britain, but Australia did not adopt the Statute until 1942. The shock of Britain's defeat in Asia in 1942 and the threat of Japanese invasion caused Australia to turn to the United States as a new ally and protector. Since 1951, Australia has been a formal military ally of the US under the auspices of the ANZUS treaty. After World War II, Australia encouraged mass immigration from Europe; since the 1970s and the abolition of the White Australia policy, immigration from Asia and other parts of the world was also encouraged. As a result, Australia's demography, culture and image of itself were radically transformed. The final constitutional ties between Australia and Britain ended in 1986 with the passing of the Australia Act 1986, ending any British role in the Australian States, and ending judicial appeals to the UK Privy Council. Although Australian voters rejected a move to become a republic in 1999 by a 55% majority, Australia's links to its British past are increasingly tenuous. Since the election of the Whitlam Government in 1972, there has been an increasing focus on the nation's future as a part of the Asia-Pacific region.

Politics

Whitlam Government was opened in 1988 replacing the provisional Parliament House building opened in 1927.]] The Commonwealth of Australia is a constitutional monarchy and has a parliamentary system of government. Queen Elizabeth II is the Queen of Australia, a role that is distinct from her position as Elizabeth II of the United Kingdom. The Queen is nominally represented by the Governor-General; although the Constitution gives extensive executive powers to the Governor-General, these are normally exercised only on the advice of the Prime Minister. The most notable exercise of the Governor-General's reserve powers outside the Prime Minister's direction was the dismissal of the Whitlam Government in the constitutional crisis of 1975. There are three branches of government.
- The legislature: the Commonwealth Parliament, comprising the Queen, the Senate (the Red house), and the House of Representatives (the Green house); the Queen is represented by the Governor-General, who in practice exercises little or no power over the Parliament.
- The executive: the Federal Executive Council (the Governor-General as advised by the executive councillors); in practice, the councillors are the prime minister and ministers of state, whose advice the Governor-General accepts, with rare exceptions.
- The judiciary: the High Court of Australia and other federal courts. The State courts became formally independent from the Judicial Committee of the Privy Council when the Australia Act was passed in 1986. The bicameral Commonwealth Parliament consists of the Queen, the Senate (the upper house) of 76 senators, and a House of Representatives (the lower house) of 150 members. Members of the lower house are elected from single-member constituencies, commonly known as 'electorates' or 'seats'. Seats in the House of Representatives are allocated to states on the basis of population. In the Senate, each state, regardless of population, is represented by 12 senators, with the ACT and the NT each electing two. Elections for both chambers are held every three years; typically only half of the Senate seats are put to each election, because senators have overlapping six-year terms. The party with majority support in the House of Representatives forms Government, with its leader becoming Prime Minister. There are three major political parties: the Labor Party, the Liberal Party and the National Party. Independent members and several minor parties—including the Greens, Family First and the Australian Democrats—have achieved representation in Australian parliaments, mostly in upper houses, although their influence has been marginal. Since the 1996 election, the Liberal/National Coalition led by the Prime Minister, John Howard, has been in power in Canberra. In the 2004 election, the Coalition won control of the Senate, the first time that a party (or coalition of governing parties) has done so while in government in more than 20 years. The Labor Party is in power in every state and territory. Voting is compulsory in each state and territory and at the federal level.

States and territories

Voting is compulsory Australia consists of six states, two major mainland territories, and other minor territories. The states are New South Wales, Queensland, South Australia, Tasmania, Victoria and Western Australia. The two major mainland territories are the Northern Territory and the Australian Capital Territory. In most respects, the territories function similarly to the states, but the Commonwealth Parliament can override any legislation of their parliaments. By contrast, federal legislation overrides state legislation only with respect to certain areas as set out in Section 51 of the Constitution; all residual legislative powers are retained by the state parliaments, including powers over hospitals, education, police, the judiciary, roads, public transport and local government. Each state and territory has its own legislature (unicameral in the case of the Northern Territory, the ACT and Queensland, and bicameral in the remaining states). The lower house is known as the Legislative Assembly (House of Assembly in South Australia and Tasmania) and the upper house the Legislative Council. The heads of the governments in each state and territory are called premiers and chief ministers, respectively. The Queen is represented in each state by a governor; an administrator in the Northern Territory, and the Governor-General in the ACT, have analogous roles. Australia also has several minor territories; the federal government administers a separate area within New South Wales, the Jervis Bay Territory, as a naval base and sea port for the national capital. In addition Australia has the following, inhabited, external territories: Norfolk Island, Christmas Island, Cocos (Keeling) Islands, and several largely uninhabited external territories: Ashmore and Cartier Islands, Coral Sea Islands, Heard Island and McDonald Islands and the Australian Antarctic Territory.

Foreign relations and military

Over recent decades, Australia's foreign relations have been driven by a close association with the United States, through the ANZUS pact and by a desire to develop relationships with Asia and the Pacific, particularly through ASEAN and the Pacific Islands Forum. In 2005 Australia secured an inaugural seat at the East Asia Summit following its accession to the Treaty of Amity and Cooperation. Australia is a member of the Commonwealth of Nations, in which the Commonwealth Heads of Government meetings provide the main forum for co-operation. Much of Australia's diplomatic energy is focused on international trade liberalisation. Australia led the formation of the Cairns Group and APEC, and is a member of the OECD and the WTO. Australia has pursued several major bilateral free trade agreements, most recently the US–Australia Free Trade Agreement. Australia is a founding member of the United Nations, and maintains an international aid program under which some 60 countries receive assistance. The 2005–06 budget provides A$2.5bn for development assistance; as a percentage of GDP, this contribution is less than that of the UN Millennium Development Goals. Australia's armed forces—the Australian Defence Force (ADF)—comprise the Royal Australian Navy (RAN), the Australian Army, and the Royal Australian Air Force (RAAF). All branches of the ADF have been involved in UN and regional peacekeeping (most recently in East Timor, the Solomon Islands and Sudan), disaster relief, and armed conflict, including the 2003 Invasion of Iraq. The government appoints the chief of the Defence Force from one of the armed services; the current chief is Air Chief Marshal Angus Houston. In 2005–06, the defence budget is A$17.5bn.

Geography and climate

Angus Houston Australia's 7,686,850 km² (2,967,909 mi²) landmass is on the Indo-Australian Plate. Surrounded by the Indian, Southern and Pacific oceans, Australia is separated from Asia by the Arafura and Timor seas. Australia has a total 25,760 km (16,007 mi) of coastline and claims an extensive Exclusive Economic Zone of 8,148,250 km² or 3,146,057 mi² (excluding the Australian Antarctic Territory). Climate is highly influenced by ocean currents, including the El Niño southern oscillation, which is correlated with periodic drought, and the seasonal tropical low pressure system that produces cyclones in northe
