What are the boundaries of the South American Plate? Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called subduction. Two parallel mountain ranges commonly develop above such a subduction zone - a coastal range consisting of sedimentary strata and hard rock lifted out of the sea (accretionary wedge), and a volcanic range farther inland (volcanic .

The orogenic (mountain-building) activities that created the Andes occurred during the American Plate and oceanic Nazca Plate periods. Relative plate motions can be calculated by using global positioning system to the accuracy of 1-2mm/year. The western coast of South America is a very good example of an oceanic to continental convergent boundary where the Nazca plate is colliding (and being subducted beneath) the South American plate.
