Water Cycle Definition - What does Water Cycle mean? The water cycle is a series of processes that a body of water goes through as it transitions between the earth's oceans, the atmosphere and land, and involves precipitation as rain or snow, drainage through rivers and streams, and evaporation into the atmosphere by heat from the sun.
The water cycle is a natural process that happens when water rotates through different forms (solid, liquid, or vapor). The process improves the quality of water. However, people do things that create water pollution.he Water Cycle (University of Washington) - Information and several activities to learn about the water cycle.
