Bitesize convection currents
WebConvection currents are present everywhere, from the atmosphere to magma within the plates. The basic principle of a convection current is that warm air rises because of the extra energy it received in the form of heat … WebThe denser cold liquid or gas falls into the warm areas. In this way, convection currents that transfer heat from place to place are set up. Convection currents can be seen in lava lamps. The wax inside the lamp warms up, becomes less dense than the liquid and so rises. When it rises, it cools and becomes denser again, so it sinks.
