Answer:

The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor. Through the water cycle, water available on Earth, so assured, friends. From the water flowing into the river, the lake, to the sea, also the water is absorbed in the soil. The water cycle has benefits for human life on Earth, most of all is a water cycle that continues to run keeping the availability of clean water. The clean water is used in various forms of our activities, such as drinking, cooking, bathing, and washing.  Water is also used to help humanity work, for example, to the watering plants on farmland, it is also used to feed the livestock on farms.
