Web a trench forms when an oceanic plate collides with another plate at a convergent boundary. Web some trenches are created as a result of erosion by running water or by glaciers (which may have long since disappeared). Web trenches are long, narrow depressions on the seafloor that form at the boundary of tectonic plates where one. When this happens, the denser.
