The Nazca plate is converging with the South American plate.
Explanation:
The Andes Mountains are formed as a result of the convergent of the Nazca plate and the South American plate.
This mountain range typifies the geology and geography of the South American continent.
- Along this convergent margin, one plate subducts beneath the other.
- The oceanic plate due to its density goes into the mantle.
- The causes the continent riding to obduct and be forced.
- With rising magmatic bodies beneath, the continent further pushes up to form the Andes ranges.
