The two major models for a mechanism to drive plate tectonics are the ridge-push, slab-pull and the convection models. the convection model relies on between the top of the convecting cell and the base of the lithospheric plate, and the push/pull model relies on the ridge and pushing the plate outward as the ridge falls in elevation

The correct answer is friction; cooling

Explanation:  The movement of tectonic plates moving over the asthenosphere (pasty part) interacting over time with each other in a geodynamic process that results in the origin of mountains and geological basins, causing seismic shocks (earthquakes and tidal waves), volcanism, magmatism and other events
