About 75 percent of our planet is covered by water or ice. The water cycle is the endless process that connects all of that water. It joins the Earth?s oceans, land, and atmosphere. The Earth?s water cycle began about 3.8 billion years ago when rain fell on a cooling Earth, forming the oceans.

The water cycle is the path that all water follows as it moves around Earth in different states. Liquid water is found in oceans, rivers, lakes?and even underground. Solid ice is found in glaciers, snow, and at the North and South Poles. Water vapor?a gas?is found in Earth?s atmosphere.

The water cycle describes how water continuously moves between Earth?s surface and the atmosphere. This movement occurs by different physical processes. Water moves into the atmosphere from oceans, lakes, and streams by evaporation. During evaporation, water changes from liquid water to water vapor (a gas).
