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 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.

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 …

The continuous movement of the mantle is known as “Mantle-Convection”. The convection currents transfer the hot and molten magma to penetrate up into the brittle lithosphere and sometimes even cross the crust at weak places like plate boundaries and hotspots.

Mar 28, 2020 · 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.

Apr 30, 2024 · Mantle convection describes the movement of the mantle as it transfers heat from the white-hot core to the brittle lithosphere. The mantle is heated from below, cooled from above, and its overall temperature decreases over long periods of time.

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.

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

Convection in the Earth's mantle is driven by cooling from the surface, not heating from below, and is unlikely to involve thermal plumes from the deep mantle.

Mar 31, 2024 · Mantle convection on Earth is a complex process that involves the movement of large-scale currents of molten rock within the Earth’s mantle. These currents are driven by the heat generated by the Earth’s core, which causes the molten rock to rise towards the surface.
