Understanding Groundwater

The video explains groundwater, its origin from precipitation, and how it moves through soil until it reaches an impermeable layer. It describes the zone of saturation and the water table, which fluctuates with precipitation levels. The video also covers aquifers, layers of permeable rock that store water, and how water is extracted from them for human use.
