  • 1. Hydrology Earth's water
  • 2. What is your definition of fresh water?
  • 3. Only 3% of all the water on earth is fresh water!!!
  • 4. Where is the fresh water? 76% - ice 23% - groundwater 1% - on the surface Pretty amazing! Note: This is a fake picture! Used here to show percent of the iceberg above water.
  • 5. Because of this property, only about 9% of an iceberg is above the water! These pictures are real! Notice the part of the iceberg below water! Ice has a lower density than water. That is why it floats in water!
  • 6. Click to view video clip on the water cycle Water Cycle impermeable permeable
  • 7. What happens to the water when it hits the ground? The above ground water (runoff) becomes part of a watershed.
  • 8. The final stop for the water in a watershed is when it reaches the ocean.
  • 9. Water is also stored underground The saturated zone is the level where the pores between the soil particles are filled with water. It is called an aquifer . The top of the saturated zone is called the water table . Its location changes based on the amount of water going underground. What do you think happens to the water table during a drought? Above the water table is the unsaturated zone . Here the pore spaces are filled mostly with air.
  • 10. A B C What is happening at each letter? Pores are the spaces between soil particles where air and/or water can be found.
  • 11.  
  • 12. Click here for a video clip on underground water We dig wells to get to the water stored in the aquifer . In fact, most of the bottled water we buy comes from there! The “confining” bed is impermeable so the water cannot go deeper into the ground.
  • 13. Look how important underground water is to the water cycle!
  • 14. Wetlands
  • 15. Video clip on watersheds and wetlands (10 minutes)
  • 16. Point and Non point pollution Video clip about non point
  • 17.
    • Can you answer these questions?
    • How much of the earth’s water is fresh water?
    • What is an aquifer?
    • Explain what a water table is.
    • What does the word saturated mean?
    • What is the difference between permeable and impermeable?
    • What is a watershed?
    • Define wetlands.
    • Why are wetlands important?
    • What is the difference between point and non point source pollution?
