Best Answer

As warm air rises, it expands and cools. The rising air soon reaches the dew point, the temperature at which the water vapor in the air condenses into droplets of water or form tiny ice crystals. Clouds form. If there is a lot of water vapor in the warm air, heavy rain or snow may fall.
