Where one plate is pushed downward beneath another plate into the underlying mantle when plates move towards each other..=)
its hard to understand
Subduction
This process is called subduction.
Ocean Trench
subduction is the process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary.
The deepest portions of the subducting plate get pulled under by the subducted plate. This is how the trench is formed. this process is at work when any subduction occurs. An oceanic-continental subduction occurs when ocean crust sinks under continental crust. The oceanic crust sinks because it is colder and denser than the continental crust. At these sites, deep-ocean trenches form, along with coastal mountains.
It is called subduction.

Ocean trenches form at areas of subduction.
Ocean lithosphere is higher density so it sinks to the bottom.
