Convection of the mantle propels the motion of the tectonic plates in the crust. The source of heat that drives this motion is the primordial heat left over from the planet's formation renewed by the radioactive decay of uranium, thorium, and potassium in Earth's crust and mantle.

Dec 13, 2019 The source of heat that drives plate tectonics is the primordial heat left over from the planet’s formation as well as the radioactive decay of uranium, thorium, and potassium in Earth’s crust and mantle. The Mantle. It forms about 83 per cent of the earth’s volume and holds 67% of the earth’s mass.

Heat Source: The presence of a heat source is important because the convection currents are generated by the differences in density of the fluid that occurs due to temperature gradients. In the case of natural convection, the fluid surrounding the heat source receives heat. Due to thermal expansion, it becomes less dense and rises above.

Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy between physical systems.Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes.Engineers also consider the transfer of mass of differing …

Jan 13, 2022 Considering a silicate mantle temperature of ∼5000 K at its bottom , a big temperature gradient across the super-Earth’s core-mantle boundary could be expected. Therefore, a large heat flow and thermal energy source are responsible for powering its molten iron convection . As the super-Earth cools, its adiabat first intersects the melting ...

Sep 12, 2019 Convection currents in the air and sea lead to weather. Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements. The ...

The power for convection comes from the sinking of the oceanic lithospheric plates, the heat generated in the mantle by radioactive decay, and the return flow of warmer mantle. Plate tectonics is critical to diamond formation in two ways: It permits the recycling of surficial carbon, and it enables mantle melt ing, both of which allow the ...
