How does convection work in the mantle?

In Earth's mantle, large amounts of heat are transferred by convection currents. Heat from the core and the mantle itself causes convection currents in the mantle. The hot rock eventually cools and sinks back through the mantle. Over and over, the cycle of rising and sinking takes place.

Explanation:

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
