WebRidge push is thought responsible for the motion of these plates. The subducting slabs around the Pacific Ring of Fire cool down the Earth and its core-mantle boundary. Around the African Plate upwelling mantle plumes from the core-mantle boundary produce rifting including the African and Ethiopian rift valleys.

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.

WebSpreading rate is the rate at which an ocean basin widens due to seafloor spreading.
