How do slab pull forces affect plate motion

WebSep 5, 2024 · How do slab pull forces affect plate motion? “slab pull” As lithospheric plates move away from midocean ridges they cool and become denser. They eventually become more dense than the underlying hot mantle. Friction between the converging plates and also the force required to bend a plate resist the movement of the plate at subduction zones. WebDec 2, 2024 · The main force on a subducting plate is the slab-pull force. This is the force due to the density contrast between a slab and its surroundings, ie., the mass anomaly of the slab in the mantle.
