The water cycle describes the continuous movement of water on, above, and below the Earth's surface, driven by solar energy. Water can exist in three forms - liquid, solid (ice), and gas (water vapor) - and changes form as it moves through the cycle of evaporation, transpiration, condensation, precipitation, collection, runoff, infiltration, storage, and either return to the seas or a repeat of the cycle. The sun's heat causes evaporation and transpiration, forming water vapor that rises and condenses into clouds and precipitates as rain or snow back to Earth, completing the cycle which is vital to life and all human activities that depend on water.
