The term for the movement of water through the Earth's water cycle is "hydrological cycle" or "water cycle." This continuous process involves the evaporation of water from surfaces, its condensation into clouds, and precipitation in various forms such as rain or snow. Water then flows into rivers, lakes, and oceans, where it can evaporate again, thus perpetuating the cycle. The water cycle is essential for regulating climate, supporting ecosystems, and providing fresh water for humans and wildlife.
