Mechanism that drives plate tectonics

WebPlate movement is thought to be driven by a combination of the motion of the seafloor away from spreading ridges due to variations in topography (the ridge is a topographic high) and density changes in the crust (density … WebBoth provide dramatic evidence of plate tectonics in the form of volcanoes and earthquakes. In this session, we investigate how these phenomena are connected to the movement of plates. As we examine what happens at and between plate boundaries, our focus shifts to the mechanisms deep within the Earth that drive what we observe at its surface.

WebSlab pull. Slab pull is a geophysical mechanism whereby the cooling and subsequent densifying of a subducting tectonic plate produces a downward force along the rest of the plate. In 1975 Forsyth and Uyeda used the inverse theory method to show that, of the many forces likely to be driving plate motion, slab pull was the strongest.
