Close window. The oceanic zone is often subdivided into five layers of differing depth. The three uppermost layers include the epipelagic zone (depth 0-200 m), the mesopelagic zone (200-1000 m), and the bathypelagic zone (often 1000-2000 m).lose window.

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.
