The Altiplano (South America)

The Altiplano, also called Puna, is a region in west-central South America in the area where the Andes are the widest. It is the most extensive area of high plateau on earth outside Tibet. The bulk of the Altiplano lies in Bolivia but its northern parts lie in Peru and its southern parts lie in Chile and Argentina.

The Pampas (South America)

The Pampas are a natural region of vast fertile lowland plains in South America that extend from the Atlantic Ocean to the Andes Mountains. These flat, fertile plains are a grassland biome that can be divided into three distinct ecoregions: the Uruguayan Savanna, the Humid Pampas and the Semiarid Pampas.
