What term describes the falling of any form of water such as rain or snow?

The term that describes the falling of any form of water, such as rain or snow, is precipitation. Precipitation refers to the process where water droplets or ice crystals in the atmosphere combine and grow heavy enough to fall back to Earth due to gravity. This can occur in various forms including rain, snow, sleet, or hail, depending on temperature and atmospheric conditions.

Other processes like condensation involve water vapor cooling and changing into liquid droplets, while evaporation refers to the transformation of liquid water into water vapor. Transpiration is the process by which plants release water vapor into the air from their leaves. Each of these terms describes a different phase or process within the water cycle, making precipitation unique as the specific term for water returning to Earth in various forms.
