Water constantly evaporates from the surface of lakes and rivers. Why doesn’t the water run out in them?

Water, having evaporated from the surface of rivers, lakes and other bodies of water, rises high into the sky. There, water particles solidify under the influence of low temperatures. When there are many such frozen small particles of water, they form a cloud. Gradually, the cloud is heavily filled with water, and the water pours back onto the ground in the form of rain. If the air temperature is low, then the rain turns into snow or hail, as the water freezes as it falls to the ground. Thus, the evaporated water returns to rivers and lakes. This phenomenon is called the water cycle in nature.
