1. Tell me everything you know about the Tuckasegee river
SI #4 due FRIDAY

2. River Systems
River systems are divided into regions called watersheds/river basins.
River systems appear dendritic meaning “tree like”
Have students come up to the sink. Get a cup of water and pour on the corner, let them observe what happens to the water. It will bunch up, and create smaller streams, which eventually join larger streams, and then go down the drain. Smaller streams are tributary's. The side of the sink is the watershed/drainage basin.

3. River Systems
A stream that flows into a larger stream is called a tributary

4. A watershed is smaller than a river basin
River Systems
A watershed is an area or ridge of land that separates waters flowing to different rivers, basins, or seas

A watershed is smaller than a river basin

6. Topography – determines where water in the watersheds will drain

7. River Systems
A river basin sends all of the water falling within it to a central river and out to an estuary or to the ocean.

8. There are 17 river basins in NC

9. There are 17 river basins in NC

10. River Basin Grading Each question is worth 2 points each
Map colored “A” quality 50 points
- 10 for everyday that it is late

12. Rivers
A river forms through Erosion (break down of materials through wind, air, or water)

13. Deposits
After rivers erode rock and soil, they deposit their load downstream
After the river erodes and transports all of that soil sand and rock, where does it go? Miners during the Gold rush in 1850s found most of their gold in the bends of rivers where most of the sediment was deposited

14. Rivers deposit sediment where the speed of the water decreases

15. Deltas
When a river meets a large body of water its current slows Its load is deposited fan- shaped pattern called a delta
