Earth's Crustal Plates. Crustal plates (tectonic plates) are the outer shell of the Earth. Continental crust and oceanic crust are the two main types of plates. Large plates like the North American Plate is considered a continental plate but also contains oceanic crust. Continental crust which contains the interior of the large continents is much older than oceanic plates. Oceanic crust is constantly being created an destroyed around the Earth's surface.
Crust is consumed in subduction zones. When two plate move together, one of them must slide under the other one. This is called subduction. When an oceanic plate and a continental plate meet, the denser oceanic plate subducts under the less dense continental plate. The subducting plate slips down into the mantle where it is heated, melts and is recycled. Thus spreading centers and subduction zones act like a conveyor belt, manufacturing crust at one end and consuming it at the other. The deepest parts of the ocean occur in trenches along subduction zones.
