Top best answers to the question «What process creates underwater trenches»

Ocean trenches are a result of tectonic activity, which describes the movement of the Earth's lithosphere… At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.

How are ocean trenches formed by subduction?

  • Some ocean trenches are formed by subduction between a plate carrying continental crust and a plate carrying oceanic crust. Continental crust is always much more buoyant than oceanic crust, and oceanic crust will always subduct. Ocean trenches formed by this continental-oceanic boundary are asymmetrical.
