South America- Central

South America is a continent located in the Western Hemisphere, mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. It is also considered as a subcontinent of the Americas,[1] which is the model used in Spanish-speaking nations and most of South America.

It is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. It includes twelve sovereign states – Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana,Paraguay, Peru, Suriname, Uruguay, and Venezuela – and two non-sovereign areas – French Guiana, an overseas department ofFrance, and the Falkland Islands, a British Overseas Territory (though disputed by Argentina). In addition to this, the ABC islands of the Netherlands and Trinidad and Tobago may also be considered part of South America.

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).

Most of the population lives near the continent's western or eastern coasts while the interior and the far south are sparsely populated. The geography of western South America is dominated by the Andes mountains; in contrast, the eastern part contains both highland regions and large lowlands where rivers such as the Amazon, Orinoco, and Paraná flow. Most of the continent lies in the tropics.

The continent's cultural and ethnic outlook has its origin with the interaction of indigenous peoples with European conquerors and immigrants and, more locally, with African slaves. Given a long history of colonialism, the overwhelming majority of South Americans speak Portuguese or Spanish, and societies and states commonly reflect Western traditions.
