The cycle that describes how water moves through the environment is known as the water cycle or hydrological cycle. This continuous process involves various stages including evaporation (water converting to vapor), condensation (vapor turning into clouds), and precipitation (water falling as rain, snow, etc.). Water then collects in bodies like rivers and oceans, contributing to the cycle's renewal as it evaporates again. The water cycle is vital for replenishing ecosystems and maintaining weather patterns.
