Step 1
C At destructive margins gravity forces lithosphere to descend into the mantle. The collision with the other plate causes both shallow and deep seismic activity.
Answer
Slab pull refers to the process at destructive plate margins where the weight of a descending oceanic plate exerts a pull on the rest of the plate. As the denser oceanic lithosphere sinks into the mantle due to gravity, this movement induces seismic activity both at the surface and deeper within the Earth. It's an essential mechanism in plate tectonics that contributes to the dynamism of Earth's geological processes.
