Ridge push (also known as gravitational sliding) 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. Although it is called ridge push, the term is … See more 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 … See more Early models of plate tectonics, such as Harry Hess's seafloor spreading model, assumed that the motions of plates and the activity of mid … See more Early ideas (1912–1962) Despite its current status as one of the driving forces of plate tectonics, ridge push was not included in any of Alfred Wegener's 1912 … See more

WebThe rigid lithosphere moves on the asthenosphere both horizontally and vertically. Plates are constantly in motion, and move about 3 cm (a little over an inch) per year because of slow convection currents in the mantle due to Earth’s internal heat and pulling and pushing on the plates as they form, cool and sink back into the mantle. WebOct 30, 2024 · In the framework of plate tectonics, the surface is represented by rigid plates separated along discrete plate boundary faults ( 1, 2 ), placing the focus on the forces acting at the edge of plates (ridge push, slab pull, and shear along transform faults) and at their base (active or passive mantle drag) ( 3 ).
