Detailed explanation-1: -Hot air is less dense than cold air, which is why hot air rises and cold air sinks, according to the United States Department of Energy.
Detailed explanation-2: -Cold air sinks. Sinking air compresses and heats. As air sinks, air pressure at the surface is raised. Cold air holds less moisture than warm.
Detailed explanation-3: -The opposite happens when air cools down. The air bubbles contract, their weight takes up much less space and so they become more dense, and sink. This can happen if the air particles move away from the source of heat; they might have risen very high, or moved to an area over a cool lake or over some shade.
Detailed explanation-4: -Convection currents are created as warm air rises and cool air sinks.
