WebJan 31, 2016 · Slab pull is the force which is caused by the sinking of the cold, dense lithosphere into the mantle. It is considered as one of the two major driving forces for the … 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?
WebDec 29, 2014 · Slab pull is defined as F SP = Δ ρg sin θV s where Δ ρ is the density contrast between the slab and the surrounding mantle, g the gravitational acceleration, θ is the dip angle of the slab, and V S the volume of the slab. The slab pulls on the plate and is resisted by viscous drag along the interface ( F SR ). WebSlab rollback refers to the process that involves an older oceanic crust, which is colder and more dense than other slabs, subducting at a steep angle. As the older slab collapses into the asthenosphere, it can "roll back" through the mantle. Slab rollback can pull the upper plate with it, causing an extension in the overlying plate, and ...
WebFeb 17, 2024 · What is slab pull? The process that occurs along a subduction zone when a dense oceanic plate falls beneath a buoyant plate, bringing the remaining plates behind it. Subduction is the process through which a tectonic plate descends into the mantle. When an oceanic plate subducts into the underlying mantle, slab pull happens.
