At the border of the South American and Nazca plate, there is a long and large mountain range called the Andes. Why did these mountains form? (1 point)
The Andes mountain range formed due to the convergence of the South American and Nazca tectonic plates. These two plates collide, with the Nazca Plate being forced beneath the South American Plate in a process known as subduction. As the Nazca Plate slides or subducts beneath the South American Plate, it pushes up the crust above it, leading to the formation of the Andes mountains. This subduction process also causes the release of pressure and melting of the Earth's mantle, which leads to the formation of volcanoes in the Andes.
