The Andes in western South America are an example of a landform that arises from the movement of the tectonic plates.

Explanation:

The Andes mountain range is the mountain range that occupies the western part of South America bordering its entire Pacific Ocean coast. It has a length of 8500 km making it the longest continental mountain range on Earth. From its north end, in western Venezuela, it crosses Colombia, Ecuador, Peru and Bolivia; It serves as a natural border between Chile and Argentina and has its southern end in Tierra del Fuego. It has a variable width between 250 and 750 km. Its average height is between 3000 and 4000 meters above sea level. Because of its important volcanic activity, it is part of the Pacific Ring of Fire.

It was formed at the end of the Mesozoic era, at the end of the Late Cretaceous, by the movement of the convergence of the Nazca plate under the South American Plate. Seismic movements and subsequent volcanic activity have been more important in the relief configuration than external erosive agents. In the current morphology are high mountain ranges, along with extensive high plateaus and deep longitudinal valleys parallel to the great mountain ranges. Transversal valleys are scarce, except in the Argentine-Chilean Andes.
