Web2 de set. de 2024 · Convection Currents in the Mantle. Heat in the mantle comes from the Earth's molten outer core, decay of radioactive elements and, in the upper mantle, friction from descending tectonic plates. The heat in the outer core results from residual energy from the Earth's formative events and the energy generated by decaying radioactive elements.
Webconvection, process by which heat is transferred by movement of a heated fluid such as air or water.
