The Andes are the longest mountain range on Earth, extending from the Tierra del Fuego archipelago in southernmost South America to Venezuela in the north. In southern Peru, the Andes consist of several mountain chains including the Western Cordillera and the Eastern Cordillera, with elevations of up to , which are separated from each other by the Altiplano.
Geography of South America
South America became attached to North America only recently (geologically speaking) with the formation of the Isthmus of Panama some 3 million years ago, which resulted in the Great American Interchange. The Andes, likewise a comparatively young and seismically restless mountain range, runs down the western edge of the continent; the land to the east of the northern Andes is largely tropical rain forest, the vast Amazon River basin. The continent also contains drier regions such as eastern Patagonia and the extremely arid Atacama desert.
