WebMay 28, 2024 · How convection occurs in the mantle? 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. Where is the Earth’s mantle?
