Ridge push (also known as gravitational slides or sliding plate force) is a proposed driving force for plate motion in plate tectonics that occurs at mid-ocean ridges as the result of the rigid lithosphere sliding down the hot, raised asthenosphere below mid-ocean ridges.
29 gru 2014 · Definition. Plate Driving Forces: The forces that drive the motions of tectonic plates at the surface. Slab Pull: The force exerted by the weight of the subducted slab on the plate it is attached to. Ridge Push: The pressure exerted by the excess height of the mid-ocean ridge.

ridge push: the force due to the buoyancy of the hot mantle rising to the surface beneath the ridge. viscous drag: the force opposing motion of the plate and slab past the viscous mantle underneath or on the side. This force balance is given by: Fridge − push + Fslab − pull − Fviscous − drag = 0.
Ridge push force influences tectonic plate movement by causing newly formed oceanic crust at mid-ocean ridges to slide away due to its elevated position. As magma erupts at these ridges and cools, it creates new crust that is warmer and less dense than the older crust.
1 sty 2021 · These sublithospheric buoyancy forces generate the plate-driving forces F sp (slab pull) and F rp (ridge push). Whether the force F bs (basal shear) is a plate-driving or plate-resisting force depends on the relationship of the surface plate velocity v p to the underlying mantle flow velocity v m (see main text for discussion).
Definition. Ridge push is a geological process that occurs at mid-ocean ridges, where the elevation of the ridge causes tectonic plates to move away from each other. This force is generated as hot magma rises to create new oceanic crust, leading to a slope that encourages the movement of plates downward and outward.
