When the oceanic plate sinks it is absorbed back into the magma.
Subduction occurs and oceanic trench is formed.
Subduction. denser oceanic plate moves under the continental plate. The oceanic plate is submerged into the mantle causing magma to rise to the surface.
tsunamis and earthquakes
the colder,oceanic plate sinks?!?!
The oceanic plate sinks into the mantle where it melts. This is replaced by new oceanic plate at the mid-oceanic ridge.

The oceanic plate usually subsides after colliding with a continental plate.

tsunamis and earthquakes
The oceanic plate is made of denser (and thinner) rock than the continental crust, so the oceanic plate gets subducted (pushed underneath) where it descends and gets melted by geothermal heat.
the colder,oceanic plate sinks?!?!
The plate with cooler, denser crust sinks under the other plate, forming a trench. There, the oceanic crust sinks down back into the mantle.
