1. Groundwater

2. Groundwater Water located below the Earth’s Surface Two zones
Zone of Aeration
Zone of Saturation
Water table is the boundary where the two zones meet
Recharge zone is the ground surface area where water enters the aquifer

3. Aquifer

4. Aquifer
A rock layer that stores and allows the flow of groundwater.

5. What is a substrate?
A substrate is the material present at the surface.
It can influence how easily water can pass into the groundwater system.
Examples: Sand, Gravel and Clay

6. Porosity Percentage of open space between individual rock particles
Influenced by the size of the particles

7. Permeability Rocks ability to let water pass through
Larger particles produce less friction
