Water Smart: The Sun, Water Cycle, & Climate - Percolation

The video explains the process of percolation, where water soaks into the ground. It describes how sandy ground allows for fast percolation due to its porosity, while clay-rich ground slows the process. As water percolates, soil and plants filter and clean it. A demonstration using cotton balls and muddy water shows how porosity can be observed. Finally, the video explains that water that percolates into the ground becomes groundwater.
