Saturated Zone

Real World Example

Imagine trying to find a place to squeeze in one more pair of shoes in an already packed closet. This is similar to the saturated zone in geology, where every tiny space in a layer of rock is completely filled with groundwater, leaving no room for more. Just as there isn't a gap for another shoe in your closet, in the saturated zone, there's no space left for additional water, because every crevice and pore is already occupied by the existing water.
