1. Terms to Know Capillarity= attraction of water to the surface of rocks. Moves against gravity. Porosity= The size of the gaps between rocks Permeability= the rate of water movement through the rock layers

2. POROSITY/PERMEABILITY

3. Porosity – The percentage of open spaces in a given volume of rock.

7. Aquifer: A body of rock in which large amounts of water can flow and be stored

8. Zone of aeration – The zone that lies between the water table and the earth’s surface.

9. Groundwater Zones Zone of saturation – The layer of the ground where all the pores are filled with water. - Water table

10. Capillary Fringe

13. 1,000,000,000,000,000

15. Wells and Springs Well – Hole that is dug to below the water table and through which groundwater is brought to the surface. Ordinary wells Artesian wells Spring – a natural flow of groundwater to Earth’s surface in places where the ground surface dips below the water table.

22. CONE OF DEPRESSION

23. Hot Springs and Geezers… I mean Geysers Hot Springs – when heated groundwater (by magma) rises to the surface. Geysers – A hot spring that periodically erupts from surface pools or small vents.

29. Caves- results by the breakdown of limestone due to carbonation
