Ocean trenches form over millions or billions of years. which statement accurately describes how ocean trenches form?

a )a plate of oceanic crust is subducted under a plate of continental crust
b) two plates of continental crust slide past each other
c) two plates of oceanic crust pull away from each other
d) a plate of continental crust collides with another plate of continental crust

A

Explanation:

When two plates collide, the denser one (usually the oceanic plate) gets subsided under the continental plate. There is very high friction between the two plates- because the plates a very rugged- consequently there is also high stress as the plates slip against one another. This causes the plates to bend at this subduction zone forming a trench.
