Mantle convection - Wikipedia
Mantle convection is the very slow creep of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface. [ 2 ] [ 3 ] Mantle convection causes tectonic plates to move around the Earth's surface.
Mantle convection: Thermal convection in the terrestrial planetary mantles, the rocky layer be-tween crust and core, in which hot material rises, cold material sinks and the induced flow governs plate tectonic and volcanic activity, as well as chemical segregation and cooling of …

Mantle Convection - an overview | ScienceDirect Topics
Mantle convection refers to the process through which excess heat is extracted from the Earth's interior by establishing ascending hot and descending cold currents in the mantle, influencing the patterns of convection and chemical mixing in the Earth's interior.
Mantle Convection - SpringerLink
2020年3月28日 · Mantle convection is the central theory for how the Earth works, i.e., what drives geological motions as well as the cooling history and chemical evolution of the planet.
Mantle Convection: Earth’s Plate Tectonic Conveyor Belt
Mantle convection is a fundamental driver of tectonic plate movements. It shapes the Earth’s surface features and plays a crucial role in geological processes such as the formation of mountains and the opening of ocean basins.
4.1: The Forces Driving Plate Motions - Geosciences LibreTexts
There are three main forces that determine the rate at which tectonic plates move as part of the mantle convection system: ridge push: the force due to the buoyancy of the hot mantle rising to the surface beneath the ridge. viscous drag: the force opposing motion of the plate and slab past the viscous mantle underneath or on the side.
Mantle plumes and their role in Earth processes - Nature
2021年5月25日 · Mantle plumes are an integral aspect of Earth’s convection system, yet, difficulty in imaging mantle upwellings led to controversies surrounding their origin, dynamics and composition.
Mantle convection | geology | Britannica
In plate tectonics: Mantle convection. Most agree that plate movement is the result of the convective circulation of Earth’s heated interior, much as envisaged by Arthur Holmes in 1929. The heat source for convection is thought to be the decay of radioactive elements in the mantle. How this… Read More

Mantle convection is the process by which the excess heat in the Earth's deep interior is transferred to its surface through the fluid-like motions of the rocks in the mantle.
