1. Groundwater/Wells, Springs & Geysers

2. What is Groundwater?
What is Ground Water?

4. Pores and Groundwater
Pores: Tiny holes or spaces between rock and soil.
Groundwater: Water that collects in pores in soil and sinks into the ground.
About 22 percent of Earth’s freshwater supply is stored in groundwater.

6. Properties affecting groundwater
Different kinds of rocks and soil can hold different amounts of groundwater.
Tightly packed holds little water
Loosely packed holds a lot of water

7. The Water Table
Upper layer of saturated rock and soil.

8. What happens with the groundwater?
How does the groundwater reach earth surface?

9. Wells
Hole dug below the water table that fills with groundwater.

10. Springs
Natural Flow of groundwater to earth’s surface.
