The water cycle is a natural process that involves the continuous movement of water from one place to another. It starts with water evaporating from the surface of the earth, then condensing into clouds, and eventually falling back to earth in the form of precipitation. There are many synonyms for the water cycle, including hydrologic cycle, water circulation, and the H2O cycle. The hydrologic cycle is often used in scientific contexts, while water circulation is a more general term that can be used in everyday speech. Regardless of the term used, understanding the water cycle is important for environmental awareness and effective water management.
