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, … 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. WebNewly formed oceanic lithosphere at mid ocean ridges is less dense than the asthenosphere, but becomes denser with age as it cools and thickens. This causes it to sink into the mantle at subduction zones, pulling slabs of lithosphere apart at divergent boundaries and resulting in sea floor spreading or rifting.

"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 ).
