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 29, 2014 · At present, the slab pull force is understood as the weight of the slab exerting a pulling stress on the plate it is attached to. The buoyancy of the slab induces flow, but the slab is strong enough to support its own weight and transmit all the stresses to its attached plate, in other words act as a stress guide (Elsasser, 1969 ). chilly polka すいみゃWebIn this model, plates move through a combination of pull from the weight of the subducting edge of the plates, and through the outward pushing of an ocean ridge where magma is rising and forming new crust (Figure 4.3.2).
