How does a convection cycle work?
GeologyConvection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid. How does convection work simple? Natural convection occurs when fluids
