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.
1 gru 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...
1 sty 2011 · 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 resisting...
1 lut 2012 · Lithospheric thickness models and slab pull plate-driving forces. Blue arrows depict slab pull edge forces for individual subduction segments.
28 sie 2017 · The main purpose of this study is twofold: (1) to develop detailed models of lithospheric strength of oceanic plates and ridge-push force, and (2) to determine the rheological and tectonic conditions for ridge-push force transmission in the interior of oceanic plates.
Although ridge-push/slab-pull is the favored mechanism for plate motion, it’s important not to underestimate the role of mantle convection. Without convection, there would be no ridges to push from because upward convection brings hot buoyant rock to surface.
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).
