WebMay 29, 2024 · What is a convection cell 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. WebApr 23, 2024 · Convection in Earth Geologists believe the molten rock deep within the earth circulates by convection currents. The rock is in a semi-liquid state and should behave like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from the heat of the earth’s core.

WebOnce Earth’s interior (or its mantle) was hot and liquid, it would have been subjected to large-scale convection, which may have enabled oceanic crust to develop above upwelling regions.
