Why do convection currents in the earths mantle turn left once they stop moving upwards?
there are convection cells which rotate clockwise and ones that rotate counterclockwise The closer to the core, the hotter the magma – this means the magma on the bottom of the mantle is hottest – once it reaches a certain temperature it rises and as it rises, it cools. When it cools down to a certain temperature – normally after it reaches the top of the mantle it can float until it cools to a certain temerature- then it sinks back down to get reheated….
