WebThe hot water then rises to the top, in the convection process. The atmosphere would be another example. The atmosphere is heated by radiation from the Sun, the atmosphere exhibits convection as hot air near the equator rises producing winds, and finally there is conduction between air molecules, and small amounts of air-land conduction. WebConvection currents are present in the air – A good example of convection current is the warm air that rises towards the ceiling in your house. The process happens as the warm air is said to be less dense …
