The Andes Mountains started forming with the breakup of Gondwana about 300 million years ago. There are 3 separate ridges in the Andes. The one to the east formed first. The last one and the Atacama desert formed 167 years ago when South America separated from Africa and ocean plates started sliding underneath parts of South America.
