28 sie 2017 · The ridge-push force has been derived from the thermal state of oceanic lithosphere, seafloor depth and crustal age data. The results of modeling show that the transmission of ridge-push related stresses in oceanic plates mainly depends on rheology and predominant tectonic conditions.
10 sie 2017 · ‘Ridge push’ refers to the force arising from the lateral pressure differences between isostatically compensated ridges and older, cooler, oceanic lithosphere. Because the magnitude of this force depends only on the thermal structure of the oceanic lithosphere, which can be calculated from the age, it is the most well constrained in ...

1 lut 2012 · We find that ridge push introduces additional tractions directed away from ridges, as expected, but the net effect on the global force balance is small, as demonstrated by Figure 5 (cf. grey curve to red).
Ridge push is the result of gravitational forces acting on the young, raised oceanic lithosphere around mid-ocean ridges, causing it to slide down the similarly raised but weaker asthenosphere and push on lithospheric material farther from the ridges.
Ridge push force and slab pull are two key forces that drive tectonic plate movements. Ridge push occurs at mid-ocean ridges, where newly formed, elevated oceanic crust slides down due to gravity, while slab pull takes place at subduction zones where denser oceanic plates sink into the mantle.
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.
