  1. EH. Hydrosphere Benchmark 1 Identify and describe regional watersheds.

  2. Key concepts: • Drainage basins • Divides • ReservoirsTributaries • Run-off

  3. Real-world contexts: Local and regional watersheds Great Lakes Basin Continental Divide

  4. What is a divide? an area of higher elevation that separates watersheds

  6. Mountain chains determine which direction the water flows. Cascade Mountains Rocky Mountains Appalachian Mountains Sierra Nevada Mountains

  7. Rocky Mountains = Continental Divide All water that falls on the eastern slopes flows into the Atlantic; all water that flows on the western slopes flows into the Pacific.

  8. What is a watershed?

  9. Michigan Watersheds

  10. tributaries = small streams that connect to larger ones

  11. Tools Maps

  12. Planning water management Evaluating potential disposal sites Analyzing pollution events which concern for both surface and ground water
