What is the water cycle?

The water cycle is the continuous process by which water circulates between the Earth's surface and the atmosphere through various stages, including evaporation, condensation, precipitation, and collection.

What are the stages of the water cycle?

The stages of the water cycle include evaporation (the transformation of water from liquid to vapor), condensation (the conversion of water vapor into liquid droplets forming clouds), precipitation (the fall of water in the form of rain, snow, sleet or hail from the clouds), and collection (the accumulation of water in bodies like rivers, lakes,
