South America is located in the Western Hemisphere, and is the southern portion of the Americas, which are sometimes grouped together as one continent.
South America can be divided into three major natural regions, each of which contains many subregions.
The Andes Mountains
Traversing the western coast of South America from north to south, the Andes are the longest continental range of mountains in the world, at about 7,000 kilometers in length. The Andes run through Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. The Andes region was created is home to many volcanoes, including the world's highest, Ojos del Salado.
The Highlands across the eastern side of the continent belong to the older geologic period, around the same time as the Appalachian Highlands. The Highlands are divided into two sections: the Guiana Highlands in the north and the Brazilian Highlands in the south.
In the lowland basin between the Eastern Highlands and the Andes Mountains, the plains are drained by the Amazon River and the Paraguay-Parana River system. The Amazon flows through the equatorial evergreen forest, while the Paraguay-Parana basin covers the fertile plains of the Pampas.
