How does the mantle convection theory work

WebSep 26, 2024 · Mantle convection is characterized by rising hot mantle material and sinking colder material, forming convection currents. It is the primary driver of plate tectonic … 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.

What You Should Know About Plate Tectonics

WebHess suggested that mantle convection drives the crust apart at midocean ridges and downward at ocean trenches, forcing the continental migrations in their wake. Hess interpreted the oceanic crust as a hydration rind on serpentinized mantle; Dietz modified this to generate oceanic crust by submarine basalt eruptions. WebMantle 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. All these elements contribute to mantle convection.
