What is rising air that coolsforming clouds and precipitation?

Rising air that cools, forming clouds and precipitation, is a key process in meteorology known as convection. As warm air rises, it expands and cools due to lower atmospheric pressure at higher altitudes. This cooling causes water vapor in the air to condense into tiny water droplets, forming clouds. When the droplets coalesce and grow large enough, they fall as precipitation, such as rain or snow.
