The mantle
subduction zone
The plate with cooler, denser crust sinks under the other plate, forming a trench. There, the oceanic crust sinks down back into the mantle.

Subduction zone
troposphere
subduction zone
new crust forms at divergint bounderies where plates move apart magma oozes up and cools down and creates new crust and the old crust moves away and sucks in the earth
subduction zone
That would be Subduction.
subduction zone
the oceanic crust slides down and burns in the mantle and forms a volcano
the earth's crust is 2100 ki. down the earth.
