Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.
For the water cycle to work, water has to get from the Earth's surface back up into the skies so it can rain back down and ruin your parade. Evaporation changes liquid and frozen water into water-vapor gas, which then floats up into the skies to become clouds.
