The Water Cycle

Water moves on the surface of Earth, in the atmosphere, and under the ground. This movement is called the water cycle.

The water cycle can happen very quickly or very slowly, even millions of years. The water cycle includes the liquid, vapor and ice states of water.

For example, it can start with the process of the Evaporation come from the Oceans and goes into the Atmosphere.In the Atmosphere the vapor condenses into a cloud. From the cloud we get rain, snow, and ice. The rain or snow sits on the surface of the ground and becomes a lake. Or the rain runs down a mountain to become a river that goes back to the Ocean so the cycle repeats.

Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor. Studies have shown that the oceans, seas, lakes, and rivers provide nearly 90 percent of the moisture in the atmosphere via evaporation, with the remaining 10 percent being contributed by plant transpiration.
