Warm air rises and then comes down as cool air, and the opposite is also true.
Clouds form as warm air rises because as air rises, it expands and cools, which can cause the air to reach its dew point temperature where water vapor condenses into water droplets, forming clouds. At lower altitudes, the air is usually warmer and has not risen enough to cool and reach its dew point, so clouds do not form as easily.
Sunlight heats the air by first warming the Earth's surface. The warm ground then heats the air directly above it through conduction. This warm air rises, creating pockets of warmer air that ultimately heat up the surrounding atmosphere.
A low pressure area is typically formed when warmer air rises, creating a decrease in air pressure at the surface. As the warm air rises, it cools, leading to condensation and cloud formation. This process can result in the development of a low pressure system, which is characterized by counterclockwise winds in the Northern Hemisphere.
Solar radiation heats the Earth's surface unevenly, causing areas to become warmer or cooler. This temperature difference results in air pressure variations, with warm air rising and cool air sinking. As warm air rises, cool air rushes in to replace it, creating wind.

Vaporized water rises because it is 100 degrees Celsius or warmer and is therefore warmer than the surrounding air and warmer air always rises above colder air.
When air is heated, it becomes less dense and expands. Since warmer air is less dense than cooler air, it rises above cooler, denser air. This movement of warmer air creates convection currents, where the heated air rises and the cooler air sinks.
Cool air rises because it is denser than warm air. As cool air sinks, it displaces the warmer air, causing it to rise. This movement creates convection currents, where cooler air sinks and warmer air rises, leading to a continuous cycle of air circulation.
Warmer air is less dense because the molecules have greater relative motion. Warm air rises over cooler, denser air.
Air is most likely to rise when it is heated. As air becomes warmer, it becomes less dense and therefore rises. This is the principle behind the formation of clouds, thunderstorms, and other weather phenomena.
