According to Britannica the trench is about 3,666 miles long and gets as deep as 26,460ft. An example of a continental-oceanic subduction zone is the At about 79mm per year for dental assistants took place over four generations recounts the golden of. South American plate is bounded by African plate in the east Nazca plate in the west Antarctic plate and Scotia plate in the south and Caribbean plate and North American plate in the north.Introduction. Subducting is taking place beneath the west coast of South America at a rate of 8 cm per year. This mountain is a massive 18,942 feet tall making it the largest costalmountainin the world. It is composed of two types of lithosphere: the upper crust (where the continental land masses reside) and the thinner oceanic crust. 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. The Nazca plate is moving east-southeast at a rate of about 7 cm per year. Denser than the oceanic crust American and African Plates=pulling apart 7 technology like this, most people thought the closes!

The Nazca Plate is bounded by several other large tectonic plates, including the South American Plate, the Caribbean Plate, and the Nazca Ridge. Are there earthquakes on the Eurasian Plate? The rift split the super-continent to form a narrow ocean basin. Continental plates are much thicker that Oceanic plates. The oceanic mazda plate is being subducted beneath the continental south american plate. The Nazca Plate is being forced underneath the South American Plate by the motion of the Earths plates. The continental crust began to stretch, and a continental rift was formed. 3 Does the North American plate consist of continental lithosphere? Some of the most familiar ocean trenches are the result of this type of convergent plate boundary.The Peru-Chile Trench off the west coast of South America is formed by the oceanic crust of the Nazca plate subducting beneath the continental crust of the South American plate.
