Detailed explanation-1: -Water flows endlessly between the ocean, atmosphere, and land. Earth’s water is finite, meaning that the amount of water in, on, and above our planet does not increase or decrease.

Detailed explanation-2: -Thanks to the water cycle, our planet’s water supply is constantly moving from one place to another and from one form to another. Things would get pretty stale without the water cycle!

Detailed explanation-3: -Water evaporates from the surface of the Earth, rises into the atmosphere, cools and condenses into rain or snow, falls as precipitation, and then collects on land in the oceans, rivers, lakes, and soil, and the cycle begins again. Well, that’s why the amount of water on Earth remains constant.
