South America is a continent crossed by the equator, with most of its area in the Southern Hemisphere. South America is situated between the Pacific Ocean and the Atlantic Ocean. It can be geographically defined by subtracting North America from the supercontinent of the Americas. It became attached to North America only recently (geologically speaking) with the formation of the Isthmus of Panama. The Andes, likewise a comparatively young and seismically restless mountain range, run down the western edge of the continent; the land to the east of the Andes is largely tropical rain forest, the vast Amazon River basin.
From the 1530s, the indigenous inhabitants of South America were invaded by European conquistadors, first from Spain, later from Portugal, who divided it into colonies. In the course of the 19th century, these colonies won their independence.
The region of South America also includes various islands, most of which belong to countries on the continent. The Caribbean territories are grouped with North America. The South American nations that border the Caribbean Sea – including Colombia, Venezuela, Guyana, Suriname, and French Guiana – are also known as Caribbean South America.
