Water that falls from the sky, it can be in different forms.. Hail, sleet, snow, rain.. Rain. As warm air rises into the atmosphere it cools. The air creates water vapor which condenses and forms into clouds. Once the clouds are big enough and are holding enough water it begins to rain.. Learning objectives.
