As subduction of the Nazca Plate continues, some of the sediments that accumulated on the ocean floor (together with some of the ocean crust) are scraped off and forced (accreted) onto the South American Plate in a process called obduction. This results in frequent shallow focus earthquakes that get deeperas the ocean plate descends further, defining a zone of earthquake foci known as a Benioff zone.

The water and gases in andesitic magma account for the explosive activity of andesitic volcanoes, which typically lie dormant for many hundreds or thousands of years. Is the Atlantic Plate thicker than the Pacific Plate? What is the relationship between continental drift and plate tectonics? 7. Does the Pacific Plate subducts under the Australian Plate?

Because continental crust is less dense than oceanic crust, oceanic crust will always be . The Andes Mountains are formed by the Nazca plate moving over the South American plate. Two major cycles of crustal deformation occurred in the Precambrian, widely separated in time from each other. Continental plates are much thicker that Oceanic plates. The South American plate was pushed upwards as a result of the Nazca plate moving over the South American plate. This was the largest earthquake ever recorded in Earths history which lasted 10 minutes in length. The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium). The subduction of the Nazca Plate is also responsible for the volcanoes in the Andes Mountains. Two locations are marked within the rift valley of East Africa . How are the Nazca and South American Plates convergent? The plates multiple convergent boundaries are what distinguishes it from other divergent plates.
