Explanation of how the groundwater is formed.

Groundwater is formed as a result of the water cycle in nature. For example, water evaporates from rivers and lakes, then it cools down in the form of precipitation. Moisture is absorbed into the soil, passes through several balls, for example, earth and sand, and then accumulates where the clay ball begins, which is very dense, and therefore water cannot seep through it. Before that, the water already has time to clear and cool.
