3. Stretch along western South America for a distance of about 5,500 miles.
The world’s second-largest range.
People living in the Andes grown crops on terraces cut into the mountain.
The Andes region also includes valleys and the altiplano, or “high plateau.”

5. The Central Plains extend eastward from the Andes and cover about 3/5 of South America.
The llanos, Gran Chaco, Amazon rain forest, and Pampas make up the Central Plains.
A tropical rain forest in the Amazon Basin covers about 40% of Brazil.
The Gran Chaco is largely uninhabited and is located mostly in Argentina.
The Pampas is Argentina’s most populated area.
The Guiana Highlands consist of tropical forests and grasslands.
The Brazilian Highlands to the south cover about ¼ of South America and consists mostly of hills and plateaus.
