"Slab pull" is a type of tectonic plate movement that occurs due to the forces of mantle convection and results in the subduction of the lithosphere, causing

ocean trenches

Explanation:

The slab pull is a type of the tectonic force that is created when the plate dips or slides downwards into the subduction zones and is characterized by the release of the heat waves. It forms a major force of the motion of the tectonic plates on the earth's crust. This force is accompanied by the impacts of the slab push.
