The correct explanation for mantle convection is:
Cooler material in the mantle moves down, and warmer material in the mantle moves up.
Mantle convection is the slow, churning motion of Earth's mantle caused by heat transfer from the interior of the Earth to the surface. Hot material from deeper within the mantle rises because it is less dense, while cooler material from near the crust sinks due to being denser. This process is one of the driving forces behind plate tectonics.
