Molten rocks are present deep inside the Earth’s surface that circulate … 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 …
