WebConvection currents enable hot air balloons to rise, and also explain why it is often hotter in houses upstairs rather than downstairs. Most of our winds are caused by convection … WebConvection is a way in which heat travels. It occurs when heat is transferred by the movement of liquids or gases. The other methods of heat transfer are conduction and radiation.

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. Webgenerated by radioactive decay in the core.
