How does the mantle convection theory work

WebApr 9, 2016 · Explanation: Convection currents happen in fluids with a heat source. Hot liquid or gas near the heat source becomes hotter and less dense, so moves upwards. This forces the cooler stuff at the top to move back down. As the hot molecules move up, they cool down and begin to drop. As the cool molecules move down, they heat up and begin … WebMay 12, 2024 · Mantle convection is like Earth’s engine.
