Question

what geological force causes ridge push?
convection currents
gravitational pull
slab pull
mantle stillness

Explanation:

Ridge push is caused by the elevated position of mid - ocean ridges. The gravitational force acts on the newly formed oceanic crust at the ridges, pushing it away from the ridge axis. Convection currents are related to mantle movement but not the direct cause of ridge push. Slab pull is related to the subduction of oceanic plates. Mantle stillness is not a factor in ridge push.

Answer:

gravitational pull
