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.
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.
29 gru 2014 · 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.
16 paź 2024 · Asymmetric strain rates pull spreading ridges in the direction of the strongest slab pull force, which partially explains why spreading ridges can migrate vast distances.
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 Force. Let's cover a final force a subducting plate would experience, the ridge-push force. This force results from the elevation of oceanic ridges above the seafloor. This difference in height leads to pressure that 'pushes' the plate away from the ridge.
1 sty 2021 · These sublithospheric buoyancy forces generate the plate-driving forces Fsp (slab pull) and Frp (ridge push).
