About The Continents

There are six to seven continents in the world. The reason why there are six TO seven continents is because some people believe that there are six continents instead of seven, they also believe that South America is part of North America. You can follow them any way, but we are going to stick with the seven continents. So ENJOY THE SHOW!!!!!!!

Slide3

North America

North America contains United States, Canada, Mexico, and Greenland.North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), about 4.8% of the planet's surface or about 16.5% of its land area. As of July 2008, its population was estimated at nearly 529 million people. It is the third-largest continent in area, following Asia and Africa, and the fourth in population after Asia, Africa, and Europe.

North America

(Spanish:

América del Norte

or

Norteamérica; French: Amérique du Nord; Dutch:

Noord-Amerika

; Papiamento:

Nort Amerika; Kalaallisut: Amerika Avannarleq) is a continent wholly within the northern hemisphere, but extending over both the western and eastern hemisphere. It is also considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the south by South America, and to the west by the Pacific Ocean.Slide4

South America

South America includes twelve countries: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela.

South America has an area of 17,840,000 square kilometers (6,890,000 sq mi). Its population as of 2005 has been estimated at more than 371,090,000. South America ranks fourth in area (after Asia, Africa, and North America) and fifth in population (after Asia, Africa, Europe, and North America). The Word

America

was coined in 1507 by cartographers Martin Waldseemuller

and Matthias Ringmann, after Amerigo Vespucci, who was the first European to suggest that the lands newly discovered by Europeans were not Indian, but a New World

unknown to Europeans.

South America is thought to have been first inhabited by humans when people were crossing the Bering Land Bridge(now the Bering Strait) at least 15,000 years ago from the territory that is present-day Russia. They migrated south through North America, and eventually reached South America through the Isthmus of Parama. Some archaeological finds do not fit this theory and have led to an alternative theory of Pre-Siberian American Aborigines.Slide5

Antarctica

Antarctica

is Earth's southernmost continent, encapsulating the South Pole. It is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14.0 million km

2

(5.4 million sq mi), it is the fifth-largest continent in area after Asia, Africa, North America, and South America. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages at least 1.6 kilometers (1.0 mi) in thickness.

Centered asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. It covers more than 14,000,000 km

2

(5,400,000 sq mi), making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures 17,968 km (11,165 mi) and is mostly characterized by ice formations.

Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Antarctica is considered a desert, with annual precipitation of only 200 mm (8 inches) along the coast and far less inland.

The temperature in Antarctica has reached −89 °C (−129 °F). There are no permanent human residents, but anywhere from 1,000 to 5,000 people reside throughout the year at the research stations scattered across the continent. Only cold-adapted organisms survive there, including many types of algae, animals (for example mites, nematodes, penguins, seals and tardigrades),bacteria , fungi, plants, and protista. Vegetation where it occurs is tundra.Slide6

Europe

Europe is, by convention, one of the world's seven continents. Comprising the westernmost peninsula of Eurasia, Europe is generally ‘divided’ from Asia to its east by the watersheds divide of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways connecting the Black and Aegean Seas. Europe is bordered by the Arctic Ocean and other bodies of water to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and the Black Sea and connected waterways to the southeast. Yet the borders of Europe—a concept dating back to classical antiquity—are somewhat arbitrary, as the primarily physiographic term "continent" can incorporate cultural and political elements.

Europe is the world's second-smallest continent by surface area, covering about 10,180,000 square kilometers (3,930,000 sq mi) or 2% of the Earth's surface and about 6.8% of its land area. Of Europe's approximately 50 states, Russia is the largest by both area and population (although the country has territory in both Europe and Asia), while the Vatican City is the smallest. Europe is the third-most populous continent after Asia and Africa, with a population of 733 million or about 11% of the world’s population. In 1900, Europe's share of the world's population was 25%.

Europe lies mainly in the temperate climate zones, being subjected to prevailing westerlies.Slide7

Asia

Asia is the world's largest and most populous continent, located primarily in the eastern and northern hemisphere. It covers 8.7% of the Earth's total surface area (or 30% of its land area) and with approximately 3.879 billion people, it hosts 60% of the world's current human population. During the 20th century Asia's population nearly quadrupled.

The place name, Asia, in various forms in a large number of modern languages is of unknown ultimate provenience. Its etymology and language of origin are uncertain. It appears to be one of the most ancient of recorded names. A number of theories have been published. English Asia can be traced through the formation of English literature to Latin literature, where it has the same form, Asia. Whether all uses and all forms of the name derive also from the Latin of the Roman Empire is much less certain.

The border between Asia and Oceania is placed somewhere in the Malay archipelago. The terms Southeast Asia and Oceania, devised in the 19th century, have had vastly different geographic meanings since their inception. Oceania has never been Asia, whatever it may have been defined to be. The chief factor in determining what islands of the Malay Archipelago are Asian has been the location of the colonial possessions of the various empires there (not all European). Lewis and Wigen assert, "The narrowing of 'Southeast Asia' to its present boundaries was thus a gradual process."

[

Currently Malaysia and Indonesia with the western half of New Guinea are in Southeast Asia (although the New Guinea territory of Indonesia is being disputed by the natives).Slide8

Africa

Africa is the world's second largest and second most populous continent, after Asia. At about 30.2 million km² (11.7 million sq mi) including adjacent islands, it covers 6% of the Earth's total surface area and 20.4% of the total land area.

With 1.0 billion people (as of 2009, see table) in 61 territories, it accounts for about 14.72% of the world's human population.

The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent has 54 sovereign states, including Madagascar and various island groups.

During the Cretaceous, Africa was populated by allosauroids and spinosaurids, including the largest known carnivorous dinosaurs. Titanosaurs were significant herbivores in its ancient ecosystems.

Cretaceous sites are more common than Jurassic ones, but are often unable to be dated radiometrically making it difficult to know their exact ages. Paleontologist Louis Jacobs, who spent time doing field work in Malawi, says that African beds are "in need of more field work" and will prove to be a "fertile ground ... for discovery."Slide9

Australia

Australia officially the Commonwealth of Australia,

is a country in the Southern Hemisphere comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands in the Indian and Pacific Oceans.

It is the world's sixth-largest country by total area. Neighbouring countries include Indonesia, East Timor, and Papua New Guinea to the north; the Solomon Islands, Vanuatu, and New Caledonia to the north-east; and New Zealand to the south-east.

For at least 40,000 years before European settlement in the late 18th century, Australia was inhabited by indigenous Australians, who belonged to one or more of roughly 250 language groups. After discovery by Dutch explorers in 1606, Australia's eastern half was claimed by Great Britain in 1770 and initially settled through penal transportation to the colony of New South Wales from 26 January 1788. The population grew steadily in subsequent decades; the continent was explored and an additional five self-governing Crown Colonies were established.

Life expectancy in Australia in 2006 was 78.7 years for males and 83.5 years for females. Australia has the highest rates of skin cancer in the world, while cigarette smoking is the largest preventable cause of death and disease. Australia has one of the highest proportions of overweight citizens among developed nations.Slide10
