What is the water cycle? The water cycle, also known as the hydrological cycle, is a continuous process through which water circulates between the Earth's oceans, atmosphere, and land. It involves several key stages: Evaporation: Water from oceans, rivers, and lakes transforms into water vapor due to heat from the sun. Condensation: As water vapor rises and cools, it forms clouds. This process is the collection of vapor molecules into liquid droplets. Precipitation: Clouds gather more water droplets until they become heavy enough to fall as rain, snow, sleet, or hail. Collection: Precipitated water collects in bodies of water, such as rivers, lakes, and oceans, and can also infiltrate the soil, replenishing groundwater. Runoff: Water from precipitation and melting ice flows over the land and returns to the oceans, ready to start the cycle anew. Each of these stages plays a significant role in sustaining life on Earth and regulating climate. The water cycle is crucial for maintaining ecosystems, drinking water supplies, and agricultural practices.
