Question

question: ____ push and slab pull drive subduction at a convergent plate boundary.

Explanation:

At convergent plate boundaries, ridge - push and slab - pull are the main forces driving subduction. Ridge - push occurs at mid - ocean ridges where new crust is formed and pushes the plates apart, while slab - pull is due to the dense subducting plate pulling the rest of the plate down into the mantle.

Answer:

Ridge
