Convection cannot take place without a source of heat. Heat within the Earth comes from two main sources: ... prevailing explanations about what drives plate tectonics have emphasized mantle convection, and most earth scientists believed that seafloor spreading was the primary mechanism. Cold, denser material convects downward and hotter ...

Heat Flow Mantle Convection and Plate Tectonics

For the past 4.6Ga, this heat has been slowly transferred from the deep interior to the surface as the Earth cools. Owing to the fact that rocks are not good heat conductors, the primary mode of heat transfer is by convection of the hot, plastic asthenosphere. The transfer of heat from the interior to the surface is measured as heat flow.

Mantle convection Introduction and History All planetary bodies retain some heat from their early formation but are inexorably cooling to space. Planetary surfaces are therefore cold relative to their hotter interiors, and thus un-dergo thermal convection wherein cold material is dense and sinks while hot material is light and rises (liquid ...

Mar 11, 2020 What process drives mantle convection? Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. Click to see full answer.

What Is The Source Of Heat That Drives Mantle Convection

Structure of Earth - Wikipedia. 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.
