  1. RAP 2/21 pg. 22 What percent of the Earth is covered by water? What percent is fresh? What percent is usable?

  2. Topic: Groundwater 14.1 Water in the Ground 14.2 Conserving Groundwater 14.3 Groundwater and Geology

  3. Distribution of Earth’s Water

  4. Groundwater Definition: Water that enters and is stored in the ground

  5. Water in the Ground • What factors affect the amount of water that enters the ground?

  6. How much water? Why? #1

  7. How much water? Why? #2

  8. How much water? Why? #3

  9. How much water? Why? #4

  10. How much water? Why? #5

  11. How much water? Why? #6

  12. Factors • Type of rock or soil • Climate • Topography • Vegetation • Land use

  13. I. Ability to Store Water A. Porosity :Percent of material’s volume that is pore space Depends on: a. Particle shape (angular or spherical) b. Sorting (similar size and shape=good sorting)

  14. B. Permeability :Rate at which water passes through material (connectedness of pores)

  15. Which is more permeable? clay, silt, sand or gravel

  16. So, what does this have to do with groundwater?

  17. Water Resources: Active Reading

  18. Gizmo 2/22

  19. RAP 2/25 pg. 22 • 1. What is the difference in porosity between a WELL sorted material and a POORLY sorted material? • 2. To drill a successful well, you would want the ground material to be both ___________ and _______________.

  20. Topic: II. Groundwater Zones*See Model GroundWater Lab Zone of aeration – area underground above the water table that can still hold water Water table – top of the zone of saturation Zone of saturation - area where water collects underground by filling all pore spaces

  21. Movie!

  24. RAP 2/26 pg 22 A • 1. Which substance (A or B) has a higher porosity? • 2. What is this picture representing? • 3. What term can you use to describe the zone of aeration? B

  25. III. Groundwater Storage in Virginia • Aquifer- porousand permeable rock/sediment layer (stores and carries groundwater in enough quantities to supply wells)

  26. B. Spring- small stream of groundwaterthat has reached the surface

  27. Watch out for C. geysers! • Shoots up hot water and steam

  28. Who knows of a famous geyser?

  29. D. Artesian well-does not need pump, sandwiched between 2 impermeable layers

  30. E. Wells

  31. 1. Cone of Depression

  32. Salt Water

  33. Unusually salty water…

  34. Impact crater in Chesapeake Bay allows salt water to come farther inland

  35. A suitable well location is shown and the recommended minimum distances between wells and various natural and man-made features are observed.

  36. Groundwater Contamination

  37. Gallery Walk: 5 Provinces and Groundwater

  38. RAP 3/1 pg 24 • A small stream of groundwater that has reached the surface is called: • A cone of depression forms when: • When drilling a well, these are two concerns the driller must address.

  39. IV. Water Budget A. Income and spending of water for a region 1. Income=rain/snow 2. Spending=water lost by use; runoff and transpiration

  40. B. Recharging 1. Water soaks into soil and is stored between grains of soil

  41. RAP 2/28 pg. 24 • What is one type of “spending” in the water budget? • What is one type of “income” in the water budget?

  42. V. Karst topography=Caverns What geologic process created this natural wonder?!

  43. Karst Topography A. General Description 1. Karst topography occurs in regions containing rock that is soluble. 2. Rock that is soluble will slowly dissolve. 3. The most common soluble rock type forming karst is limestone. 4. Rainwater dissolves limestone (CaCO3) more readily because it is acidic. 5. Rainwater reacts with carbon dioxide in the air to form carbonic acid.
