The main reason for the water cycle in nature.

Every day, a huge amount of liquid falls on the surface of the Earth, as well as returns to the atmosphere. How does this happen? Water evaporates from the surface of reservoirs, condenses into clouds and precipitates. Also, water evaporates from plants, glaciers. The main driving force behind the water cycle is solar energy, which heats the water.

When water falls on the ground (precipitation), part of it instantly evaporates back into the atmosphere, and most of it is absorbed into the ground, forms reservoirs, nourishes the soil. If there is a surface that does not absorb water (stones, asphalt), water moves along the surface of the earth.
