Step 1
C At destructive margins gravity forces lithosphere to descend into the mantle.
Answer
The process of slab pull occurs when the denser oceanic lithosphere descends into the mantle at destructive plate boundaries. This downward movement pulls the rest of the plate along, causing seismic activity as the subducting slab interacts with the mantle and other tectonic plates.
