Low flat areas along the coast, or coastal plains, can be found in South America where the Atlantic Ocean meets the northeastern coast of Brazil and where the Pacific Ocean meets the western coasts of Peru and Chile. Both areas of coastal plains are extremely arid, with the western coastal plains housing the driest region in the world, the Atacama Desert.
South America has three significant river basins belonging to the Amazon, Orinoco and the Paraguay and Parana river systems.
