A deep ocean trench typically forms at a subduction zone, which is a convergent plate boundary where one tectonic plate is forced beneath another into the mantle. This process results in the formation of deep trenches in the ocean floor, such as the Mariana Trench in the western Pacific Ocean.
A deep ocean trench is likely to form where two oceanic plates push together in a convergent boundary. This is because one of the plates subducts beneath the other, creating a deep trench.
When two of Earth's oceanic plates collide, they can form a deep valley called a trench. Trenches are often found in subduction zones where one plate is forced beneath the other, creating a deep depression in the ocean floor.

A convergent plate boundary causes a trench to form. This occurs when two tectonic plates collide, with one plate sinking beneath the other due to its greater density. This process creates a deep trench in the Earth's crust.
The Acapulco Trench was formed at a convergent plate boundary where the Cocos Plate is subducting beneath the North American Plate. This subduction process created the trench and is associated with deep-sea trenches, volcanic arcs, and seismic activity.

Ocean trenches form at areas of subduction.
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
A deep-ocean trench is a long, narrow depression in the ocean floor where tectonic plates are being pulled into the Earth's mantle in a process called subduction. These trenches are some of the deepest parts of the ocean and are typically associated with intense seismic activity and volcanic processes.
When oceanic crust is pushed under continental crust in a subduction zone, a deep trench is formed at the boundary between the two plates. The oceanic crust then descends into the mantle, creating a convergent plate boundary. This process can lead to the formation of volcanic arcs on the overriding continental plate.
