What Causes Convection Currents on the Mantle? Sciencing

WebHolmes theorized that convection currents move through the mantle the same way heated air circulates through a room, and radically reshape the Earth’s surface in the process. He proposed that upward convection might lift or even rupture the crust, that lateral movement could propel the crust sideways like a conveyor belt, and that where ... WebThe convection currents in the mantle are very similar to cooking a pot of soup. When a pot of soup is placed on a stove, the soup at the bottom of the pot is heated. As the soup warms up, it rises to the top of the pot. The cooler soup is more dense than the warm soup and begins to sink. This soup is then heated, and the process repeats.
