Key Geographical Coordinates
The South Central Andean Region’s coordinates vary. It is generally found between latitudes 10°S and 30°S. Its longitudinal span covers a large part of western South America.
Geological Formation and History of the Andes
The Andes mountains were formed by the subduction of the Nazca Plate under the South American Plate. This has led to a rich geological history. It includes tectonic activity, volcanic events, and mountain building.
Tectonic Activity and Mountain Building
Tectonic activity is key to the Andes’ formation. The Nazca Plate’s subduction compressed and thickened the Earth’s crust. This caused the mountains to rise, a process called orogenesis.
Volcanic Features in the Region
The Andes are home to many volcanoes and volcanic fields. These are due to the subduction process. It melts the Earth’s mantle, causing magma to rise to the surface.
