The water cycle, also known as the hydrological cycle, is the continuous process of water moving from the Earth's surface to the atmosphere and back again. It involves evaporation, condensation, precipitation, and runoff. Water evaporates from bodies of water, such as oceans, lakes, and rivers, due to the heat from the sun. The water vapor then rises into the atmosphere, where it cools and condenses to form clouds. When the clouds become heavy with water droplets, precipitation occurs in the form of rain, snow, sleet, or hail. This water then flows over the land surface as runoff, eventually making its way back to the oceans or other bodies of water to start the cycle again.
