Why plates are moving in slab pull?
“slab pull” As lithospheric plates move away from midocean ridges they cool and become denser. They eventually become more dense than the underlying hot mantle. After subducted, cool, dense lithosphere sinks into the mantle under its own weight. This helps to pull the rest of the plate down with it.
What is the difference between ridge push and slab pull Brainly?
Answer. Explanation: The difference between ridge push and slab pull is that the ridge push is caused by the potential energy gradient from the high topography of the ridges while slab pull is caused by the negative bouyancy of the subducting plate.
Is slab pull theory a form of convection?
The motion of tectonic plates is driven by convection in the mantle. There are three main forces that determine the rate at which tectonic plates move as part of the mantle convection system: slab pull: the force due to the weight of the cold, dense sinking tectonic plate.
How does ridge push effect slab pull Brainly?
Answer: “ridge push” The lithosphere thickens with gap (and time) away from the midocean ridge. “slab pull” As lithospheric plates move away from midocean ridges they cool and become thick. They eventually become more dense than the underlying searing mantle.
What are the main features of plate tectonics?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
Why are there tectonic plates?
Plate tectonics shapes the surface of our planet, but it also runs much deeper: Plate movement is the surface expression of convection in Earth’s interior. Mantle convection is driven by temperature differences between the hot interior and the gradually cooling outer layers of the planet.
