Although ridge-push/slab-pull is the widely favoured mechanism for plate motion, it’s important not to underestimate the role of mantle convection. Without convection, there would be no ridges to push ...

WebJan 5, 2016 · Slab pull, or the force generated by dense oceanic plates acted on by gravity, pulls parts of the lithosphere into the mantle after subducting under less dense … 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 … See more • Mid-ocean ridge • Seafloor spreading • ridge push See more • Schellart, W.

The third force that causes the tectonic plates to move is the slab pull. This force occurs … WebThese studies support interpretation that the plume may only weaken the lithosphere and so may play a localized force and that extension was mainly influenced by slab-pull forces that were transferred for a large distance into the interior of … WebFigure 10.29 The ridge-push/slab-pull model for plate motion, in which the lithosphere is the upper surface of the convective systems.
