That is because its outer surface is composed of about 20 tectonic plates, enormous sections of Earths crust that roughly fit together and meet at places called plate boundaries.Plate boundaries are important because they are often associated with earthquakes and volcanoes. There is a convergent boundary and after oceanic crust has subducted continental crust collides with continental crust. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. It also lies above a hotspot, the Iceland plume.

All three trenches are places where one tectonic plate is subducted beneath another. The directional trend of both the cordilleras generally is north-south, but in several places the Cordillera Oriental bulges eastward to form either isolated peninsula-like ranges or such high intermontane plateau regions as the Altiplano (Spanish: High Plateau), occupying adjoining parts of Argentina, Chile, Bolivia, and Peru. What type of convergent plate boundary is responsible for formation of the Appalachian mountains? However, through the use of more advanced techniques, researchers in the early 21st century were able to determine that the uplift started much earlier, about 25 million years ago.
