Presentation Transcript

  1. Water

  2. In what forms do we find water on Earth?

  3. Oceans - salt water

  4. Rivers – fresh water

  5. Water vapor rising from a hot spring

  6. Glacier: Himalayas Credit: DEP Kumar/UNEP/Topham

  7. The Polar Ice Cap

  8. Water cycle diagram

  9. Evaporation • Heat energy from the sun causes water in puddles, streams, rivers, seas or lakes to change from a liquid to a water vapor. • This is called evaporation. • The vapor rises into the air and collects in clouds.  

  10. Water evaporating off a car roof

  11. Condensation • Water vapor collects in clouds. As the clouds cool the water vapor condenses into water drops. • This is called condensation. • These drops fall to the earth as rain, snow or hail.

  12. Water can condense on glass.

  13. Oregon coast w/clouds

  14. Cloud types

  15. Precipitation • Water falls to the earth from clouds. Mainly as rain, but sometimes as snow and hail. • This is called precipitation.

  16. Rain Where does water go after it rains?

  17. Rain water either soaks into the ground and becomes part of an aquifer or runs off to join other surface water (creeks, rivers, oceans etc.)

  18. Snow White?

  19. White Snow

  20. Hail bouncing off the interstate

  21. Transpiration • Transpiration is the process by which plants lose water out of their leaves.  • Transpiration gives evaporation a bit of a hand in getting the water vapor back up into the air.

  22. Diagram showing Transpiration

  23. This bag tied around a plant stem has trapped water vapor given off through transpiration.

  24. What is a Watershed? The simple definitionIt's the area of land that catches rain and snow and drains or seeps into a marsh, stream, river, lake or groundwater.

  25. Watersheds are natural systems that link the land and water resources and the living organisms, including people, within its boundaries. How we live on the land affects the quality and quantity of water resources within the watershed. 

  26. Wisconsin’s Watersheds

  27. Lower Wisconsin Watershed

  28. Lower Wisconsin Watershed

  29. Watershed Name: Castle Rock

  33. Skillet Creek Hwy W bridge.

  34. Skillet Creek bottom near Hwy 159.

  35. The Baraboo Rapids

  36. Overlooking Baraboo

  37. Pine creek flowing under Hwy. Co. W

  38. Close up of the stream at Hwy 113.

  39. Simply Impervious!

  40. Riparian Buffer Zone - area alongside stream where vegetation protects the stream from runoff. shade
