Question

question: ____ push and slab pull drive subduction at a convergent plate boundary.
answer input:
spelling counts but capitalization doesn’t.

Explanation:

In the context of plate tectonics (a subfield of Geography within Natural Science), the forces that drive subduction at convergent plate boundaries are "ridge push" (where new material at mid - ocean ridges pushes the plates) and "slab pull" (where the denser subducting slab pulls the rest of the plate). So the missing term here is "ridge".

Answer:

ridge
