WebApr 15, 2024 · The Mantle Convection and Its Role in Plate Movements. Mantle convection is a critical phenomenon deep within the Earth’s mantle and drives tectonic plate motion. The movement of the plates is affected by the transmission of heat within the mantle, which causes a circulation of material and the production of forces. WebSep 2, 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.
