Earth's water is always moving in a process called the water cycle. This process transfers water from Earth's surface into the atmosphere and back again. First, the sun's energy makes water from oceans, lakes, and rivers evaporate or change from a liquid to a gas called vapor, which rises into the atmosphere and cools.

As it cools, the gas begins to condense or change back into a liquid, and millions of tiny drops of water form into clouds. Then the larger droplets of water fall to the ground as rain, snow, sleet, or hail, which are all forms of precipitation. Finally, this water can seep into the ground or fall into a larger body of water. Eventually, the water evaporates again, and the cycle repeats itself.
