What is an ocean trench? Where do they occur?
Answer (2)
Oceanic trenches occur at destructive plate boundaries.
They are where the oceanic plate slides under the continental plate, forming a trench.
Ocean trenches are deep depressions in the ocean floor formed at destructive plate boundaries where one tectonic plate slides under another. They are primarily found along the edges of continents and in tectonically active regions. Notable examples include the Mariana Trench and the Peru-Chile Trench.
