How do ridge push and slab pull cause plate motion?

WebWhen plates collide at a plate boundary in a subduction zone, this force will resist movement; it directly resists all the driving forces associated with plate tectonics. … WebOne explanation for plate movements is slab pull. Plates are extremely heavy so gravity acts upon them, pulling them apart. Alternatively, as shown in the diagram, convection currents under... tsevernsauctioneer

Slab pull - Wikipedia

WebAug 31, 2024 · Slab pull is the force exerted by a dense oceanic plate sinking into the mantle at a convergent plate boundary. Slab pull is a key force acting on plate motion because it has been proven to greatly affect the velocity of a plate, not to mention create dramatic volcanoes. Is slab pull caused by convection currents? WebSlab 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.

In 1975 … WebThe forces acting against the motion of the plates are more di cult to calculate, because they are driven by activity in the mantle and are not directly observed. In this exercise, …

WebThese sinking slabs could affect plate motion in one of two ways. A slab can directly drag a plate toward the subduction zone if it is joined to a plate. On the other hand, a slab that is not securely fastened to a plate cannot pull directly on the plate. Instead, when it sinks, it creates mantle circulation patterns that act as a kind of ...
