Study with Quizlet and memorise flashcards containing terms like Ridge Push, -Elevation produces a slope down and away from the ridge- as the rock that forms from the magma is very hot, it is less dense and more buoyant than the rocks farther away from the Mid-ocean ridge, - Scientists used computer models to show that the cooling, subsiding ...
Define the following mechanisms (mantle convection, ridge push, gravity pull) and explain how each drives movement of lithospheric plates. Convection: magma heats, rises, & cools as it touches the bottom of a plate. It will then sink & as it sinks it will pull the plate with it.
Ridge push occurs at mid-ocean ridges where newly formed, elevated oceanic crust pushes neighboring plates apart due to gravity. In contrast, slab pull occurs at subduction zones when a denser tectonic plate sinks into the mantle, pulling the rest of the plate along with it.
Ridge push is a geological process that occurs at mid-ocean ridges, where the elevated position of the ridge causes the surrounding tectonic plates to be pushed away from the ridge and towards subduction zones.
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.
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.
