What is the earth's hydrolic circle?

The Earth's hydrologic cycle, also known as the water cycle, is the continuous process by which water is circulated on Earth through evaporation, condensation, precipitation, and runoff. Water evaporates from bodies of water and land surfaces, condenses into clouds, falls back to Earth as precipitation, and then flows back into bodies of water or is absorbed by plants. This cycle helps regulate the distribution of water on Earth.
