Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents. Ridge push. Gravitational force that causes a plate to move away from the crest of an ocean ridge, and into a subduction zone. slab pull.

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.

3 paź 2024 · As the crust moves away from a mid-ocean ridge, it cools and becomes denser and thicker. This causes the lithosphere to slope away from the ridge and gravity pulls the lithosphere down this slope, pushing it forwards. This is known as gravitational sliding (or ridge push)
23 sie 2020 · Ridge push –magma rises as the plates move apart. The magma cools to form new plate material. As it cools It becomes denser and slides down away from the ridge. This causes other plates to move away from each other. Slab pull – The denser plate sinks back into the mantle under the influence of gravity.
