Water Smart: Water on Earth - Groundwater

The video explains the concept of groundwater, emphasizing its presence beneath the Earth's surface. It describes the percolation process, where rain and melted snow soak into the ground, forming aquifers. These underground water reserves are often clean enough for drinking, leading to the use of wells to access them. The video also covers how plants efficiently draw groundwater through their roots using capillary action.
