WebOne side in the argument holds that the plates are only moved by the traction caused by mantle convection. The other side holds that traction plays only a minor role and that two … WebSep 5, 2024 · How do slab pull forces affect plate motion? “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. Friction between the converging plates and also the force required to bend a plate resist the movement of the plate at subduction zones. shared great grandparents

How Mantle Slabs Drive Plate Tectonics Science

WebNewly formed oceanic lithosphere at mid ocean ridges is less dense than the asthenosphere, but becomes denser with age as it cools and thickens. This causes it to sink into the mantle at subduction zones, pulling slabs of lithosphere apart at divergent boundaries and resulting in sea floor spreading or rifting. Where slab pull is not the main ... WebJan 17, 2024 · The main force driving this plate motion (although there are other lesser forces) is the "slab pull" that arises when plates sink into the mantle under their own weight at subduction zones. In divergent zones, this pulling motion uncovers the hot deep mantle rock of the asthenosphere. As the pressure eases on the deep rocks, they respond by ... WebApr 15, 2024 · Fact: The plates are set in motion, away from the mid-ocean ridges, by a horizontal force and other phenomena such as mantle convection and slab pull. Slab Pull and Its Role in Continental Drift.

Plate Tectonics—What Are the Forces that Drive Plate Tectonics?

WebMost movement occurs along narrow zones between plates where the results of plate-tectonic forces are most evident. There are four types of plate boundaries: Divergent … WebMost movement occurs along narrow zones between plates where the results of plate-tectonic forces are most evident. There are four types of plate boundaries: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another.
