The hydrological cycle, or water cycle, is a remarkable natural process that ensures the continuous circulation of water on our planet. It begins with evaporation, where the sun’s warmth transforms liquid water into vapor. This vapor rises, cools, and condenses into clouds. Next comes precipitation, where clouds release water droplets back to Earth in the form of rain, snow, or hail. Water then replenishes our rivers, lakes, and oceans, sustaining life and ecosystems. Through infiltration, some of it seeps into the ground to replenish underground aquifers. Lastly, plants contribute by releasing water vapor through transpiration. The water cycle, a vital Earth system, underscores the importance of preserving this life-giving resource.
