GEOLOGY

Detailed explanation-1: -The Andes Mountains of South America run parallel to the Peru-Chile Trench, created as the Nazca Plate subducts beneath the South American Plate. The Andes Mountains include the world’s highest active volcano, Nevados Ojos del Salado, which rises to 6, 879 meters (over 22, 500 feet) along the Chile-Argentina border.

Detailed explanation-2: -The Andes Mountains are part of the Southern Cordillera formed from subduction zone volcanism at the convergent boundary of the Nazca plate and the South American plate.

Detailed explanation-3: -The Andean volcanism is a result of subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate. The belt is subdivided into four main volcanic zones that are separated from each other by volcanic gaps. The volcanoes of the belt are diverse in terms of activity style, products and morphology.

Detailed explanation-4: -The ongoing subduction, along the Peru–Chile Trench, of the Nazca Plate under the South American Plate is largely responsible for the Andean orogeny.

Detailed explanation-5: -The South American Plate is the smallest major plate On the west side of South America, it experiences devastating earthquakes due to the convergent plate tectonic boundaries. But the eastern edge lies in the Atlantic Ocean at a divergent plate boundary.
