Volcanoes are found along the Andes Mountains in South America.  
They were formed when the Nazca tectonic plate collided
with and slid under the South American plate.

Granite mountains were formed after the collision of the tectonic plates
where lighter rocks became magma and 'boiled' up to become granite.  
Torres del Paine has a number of granite peaks extend 8,200
feet above sea level.
