Explanation:
Detailed explanation-1: -Mantle convection is the process by which the excess heat in the Earth’s deep interior is transferred to its surface through the fluid-like motions of the rocks in the mantle.
Detailed explanation-2: -The mantle is heated from below (the core), and in areas that are hotter it rises upwards (it is buoyant), whereas in areas that are cooler it sink down. This results in convection cells in the mantle, and produces horizontal motion of mantle material close to the Earth surface.
