ELI5: Explain Like I'm 5

Phreatic zone

The phreatic zone is the area underground where water fills up little spaces between rocks and soil. Think of it like a giant water tank hidden under the ground.

When rain falls or snow melts, it seeps down into the ground and fills up the little spaces in the rocks and dirt. This is where the water lives in the phreatic zone.

The phreatic zone is really important because it helps keep groundwater, which is the water that fills up underground spaces, clean and fresh. This is because the ground acts like a natural filter, removing impurities from the water as it trickles through the soil and rocks.

Animals and plants also rely on the phreatic zone for their water needs. The water from the phreatic zone can be pumped up to the surface and used for drinking, irrigation, and other things we need water for.

So remember, the phreatic zone is like a big underground water tank that keeps our groundwater clean and provides water for animals and plants.
