Mantle convection - Wikipedia
Simplified model of mantle convection: [1] Whole-mantle convection. 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. [4]
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 …

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 - 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 - Education | National Geographic Society
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 plumes and their role in Earth processes
2021年5月25日 · Localized hot upwelling plumes are expected in any terrestrial-type planet mantle, where convection operates through bottom heating in a temperature-dependent viscosity fluid of uniform ...
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.
Mantle Convection and Plate Tectonics: Toward an Integrated
2000年6月16日 · Mantle convection and plate tectonics provide the central framework linking the subdisciplines of solid Earth science, including geochemistry, seismology, mineral physics, geodesy, tectonics, and geology. A successful model …
The Dynamics of Plate Tectonics and Mantle Flow: From Local …
2010年8月27日 · Mantle convection and associated plate tectonics are principal controls on the thermal and geological evolution of the Earth. These processes are central to our understanding of the origin and evolution of tectonic deformation, the evolution of the thermal and compositional states of the mantle, and ultimately the evolution of Earth as a whole.
