The water cycle describes the movement of water on, above, and below the surface of the Earth. In this movie, you'll learn about different parts of the cycle, including evaporation, condensation, and precipitation. Precipitation is water that falls from the sky, such as snow, rain, sleet, and hail. You'll learn how water from precipitation adds to groundwater and creates runoff into our streams, lakes, and oceans. You'll find out why you should conserve water, an important natural resource.
