Prior to 20 The North American plate is moving to the west-southwest at about 2.3 cm (~1 inch) per year driven by the spreading center that created the Atlantic Ocean, the Mid Atlantic Ridge. The Nazca Plate straddles the west coast of South America. below the continental crust(subduction zone) because it is denser. Some scientists believe that the plate is oceanic in nature, while others contend that it is continental. The movement of plates along a tectonic boundary is referred to as convergent movement. The Andes are formed due to convergence between Nazca plate (oceanic plate) and the South American plate (continental plate). The Mid-Atlantic Ridge, for instance, separates the North American plate from the Eurasian plate, and the South American plate from the African plate.The East Pacific Rise is a mid-ocean ridge that runs through the eastern Pacific Ocean and separates the Pacific plate from the North American . The oceanic plate (oceanic crust) subducts under the continental plate. A supercontinent, Pangea, formed approximately 300 million years ago in the Paleozoic era (Lovett, 2008), and it began to break apart 200 million years ago (Condie 1989).
