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 includes processes such as evaporation, condensation, precipitation, and runoff.
The importance of the water cycle is vast. It helps regulate the Earth's temperature by transporting heat energy around the globe. It also plays a crucial role in providing fresh water for plants, animals, and human consumption. Additionally, the water cycle is essential for maintaining ecosystems, supporting agriculture, and sustaining life on Earth. Overall, the water cycle is a fundamental process that ensures the availability of water resources and the balance of our planet's climate.
