Where are the Andes Mountains? South America
The Andes mountains run down the Pacific side of South America
About 199 million years ago, near the beginning of the Jurassic period, was the time of the dinosaurs. That’s when the supercontinent of Pangaea broke up and the pieces began to float away from each other. The supercontinent split up into the continents we have today.
The Pacific Ocean tectonic plate started to squeeze under the South America plate, pushing up the Andes mountains that now run all along the west side of South America.

The Andes mountains are far older than the Alps, the Rockies, or the Himalayas. They’re the oldest high mountains in the world, though they are newer than the Appalachian mountains or the Ural mountains.
The Andes were the original home of llamas and wild tomatoes and potatoes, among other things.
