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.

2024年4月30日 · 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: 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 …
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: 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.
Mantle Convection in Terrestrial Planets | Oxford Research …
Mantle convection governs the geological activity and the thermal and chemical evolution of terrestrial planets and understanding the physical processes of convection helps us reconstruct histories of planets over billions of years after their formation.
Mantle convection - SpringerLink
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.

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.
Sluggish thermochemical basal mantle structures support their …
2024年11月19日 · Role of plate tectonics in the topology of basal mantle structures. Three-dimensional thermochemical mantle convection models in spherical geometry on the Yin-Yang grid 17,18 were conducted with ...
Mantle convection in both the plate and plume modes leads to cooling of the Earth over time. Simple, globally integrated energy balances can allow us to formu-late and test hypotheses about the thermal history of the Earth. 1 The uid mantle We know the mantle is solid: seismic shear waves pass through it e ciently, travers-
