The orogenic (mountain-building) activities that created the Andes occurred during the American Plate and oceanic Nazca Plate periods. This tectonic collision developed a composite transform-convergent margin characterized by normal and strike-slip faults that formed extensional/pull apart basins along the western margin of Peru. Several hotspots have formed volcanic islands as a result of the movement of the Nazca Plate, which has also created seamount chains beneath South Americas surface. In this lesson we'll be exploring the forces behind plate tectonics. Oceanic crust is thinner but denser, while the continental crust The term sial refers to the composition of the upper layer of the Earths crust, It is sometimes thought to be a continental crust, despite the fact that it is absent from the vast oceanic basins, but it is a geochemical term rather than a plate tectonic one.
