Conduction Convection Radiation - Energy transfer

Aug 02, 2021 Conduction, Convection, Radiation – Energy transfer during heating cooling. There are three different processes through which energy can be transferred during heating and cooling: conduction, convection, and radiation. Conduction is the transfer of heat through a substance as a result of collisions between neighbouring vibrating particles ...

Observing Convection Currents

cosmic debris. How and why the escape of interior heat becomes concentrated in certain regions to form convection cells remains a mystery. Until the 1990s, prevailing explanations about what drives plate tectonics have emphasized mantle convection, and most earth scientists believed that seafloor spreading was the primary mechanism.

What is the main heat source for mantle convection?

The heat driving mantle convection has three sources. 'Primordial' heat (left over from the accretion and differentiation that led to the formation of Earth's core) contributes 20 to 50% of the heat. Heating due to the decay of radioactive isotopes (mainly potassium, thorium, and uranium) contributes 50 to 80%.

The mantle is hot mostly because of heat conducted from the core. Convection: If a material is able to move, even if it moves very slowly, convection currents can form. Convection in the mantle is the same as convection in a pot of water on a stove. Convection currents within Earth’s mantle form as material near the core heats up.
