The Andes block moisture from the Atlantic Ocean and Amazon basin from reaching the west coast areas of South America, resulting in the formation of rainshadow deserts such as the Atacama and Sechura.
In the South Andes Mountains and some live in South American deserts.
In the northern half of South America, the deserts (Atacama, Sechura) are on the western side of the Andes. In the southern half of the continent, the deserts (Patagonian and Monte) are to the east of the Andes Mountains.
The Andes Mountains form the 'spine' of South America
The Andes mountains were formed from the interaction of the South American Plate and the Nazca Plate, which is a convergent plate boundary. The Nazca Plate is subducting beneath the South American Plate, leading to the uplift and formation of the Andes mountains.
The Andes Mountains running along the western edge of South America were formed by collisions between the South American plate and the
The Andes Mountains
The Andes are an extension of the North American Rocky Mountains and the South American mountains that continue up through Central America.

The Andes act as a barrier to moisture coming from either the Atlantic or Pacific Oceans, forming rain shadow deserts.
A major mountain range in South America is the Andes Mountains. The Andes Mountains run the entire length of the continent from north to south on the west coast of South America.
