What term refers to the falling of any form of water from the atmosphere to the Earth's surface?

The term that refers to the falling of any form of water from the atmosphere to the Earth's surface is precipitation. This includes all forms of water, such as rain, sleet, snow, and hail, which occur when moisture in the atmosphere condenses and falls to the ground due to gravity. Understanding this concept is crucial in environmental science because precipitation plays a vital role in the water cycle, influencing climate and weather patterns as well as providing necessary water for ecosystems, agriculture, and human use.

In contrast, infiltration pertains to the process through which water soaks into the soil from the surface, evaporation refers to the transformation of liquid water into vapor as it gains energy, and runoff signifies the movement of water, typically from rain or melting snow, across the land surface into bodies of water. Each of these processes is distinctly involved in the overall water cycle, but they do not describe the specific action of water falling from the sky, which is what defines precipitation.
