WebMay 23, 2024 · Gravity causes the higher plates to push away the lithosphere that is placed in the further parts of the ridge. The third force that causes the tectonic plates to move is the slab pull. This force occurs when the older plates start to sink. As the plates age, they become colder, which makes them denser than the mantle beneath them. WebRIDGE PUSH DEFINITION. Rising mantle material at the mid-ocean ridge creates a potential for plates to move away from the ridge with a force. SLAB PULL. When tectonic plates collide the denser plate will sink into the mantle along … WebJan 17, 2024 · The ridges are only a few kilometers high but hundreds wide. The slope on the flanks of a ridge means that diverging plates get an assist from gravity, a force called "ridge push" that, together with slab pull, accounts for most of the energy driving the plates. On the crest of each ridge is a line of volcanic activity. hatch pumping bra
