It starts with evaporation from bodies of water, condensation into clouds, and precipitation back to the earth. This cycle also includes transpiration from plants and sublimation from ice to vapor. The majority of Earth's water is saltwater, with only a small percentage being freshwater in lakes, rivers, and groundwater.

This occurs through processes such as evaporation and transpiration, condensation, and precipitation. The water cycle is driven by solar energy and gravity.
