The earth's interior heat and pressure drive a process of heat transfer in the mantle called convection.
Explanation;
Convection is the process of heat transfer that occurs in fluid through convection current. This process may occur in a natural setting such as in the earth's mantle.
The plate tectonics in the earth surface are driven by the convection currents in the magma. The intense heat in the core of the earth causes molten rocks in the mantle to move in a pattern called convection cell that results from the cooling of the rising denser warm material which eventually sink.
This transfer of the heat from the mantle to the surface of the earth by convection is similar to the hot water, which involves convection currents.
