Mantle Convection: Earth’s Plate Tectonic Conveyor Belt
WebThe mantle’s convective motions break the lithosphere into plates and move them around the surface of the planet. These plates may move away from, move by, or collide with each other. This process forms ocean basins, shifts continents, and pushes up mountains. Scientists study mantle convection, or the flow of hot rock in the Earth's deep … WebDec 2, 2024 · 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 ridge push: the force due to the buoyancy of the hot mantle rising to the surface beneath the ridge. WebHeat is transferred by conduction, convection, and radiation. How Does Convection Occur in Earth's Mantle? The heating and cooling of the flood in the Earth's Mantle changes the fluid's density, and along with the force of gravity, combine to set convection currents in motion.
