How rocks respond to stresses within the Earth’s crust

Part A

1. Explain how rocks respond to stresses within the Earth’s crust by brittle, elastic, or plastic deformation, or by fracturing
2. Summarize how rocks become folded
3. Briefly describe the different types of faults, including normal, reverse, thrust, and strike-slip
4. Briefly describe the difference between strike and dip
5. Describe a drainage basin and explain the origins of different types of drainage patterns
6. Describe the formation of stream terraces
7. Describe the processes by which sediments are moved by streams and the flow velocities that are necessary to erode them from the stream bed and keep them suspended in the water
8. Explain how natural stream levees form
9. Describe the types of environments where one would expect to find straight-channel, braided, and meandering streams
10. Explain the concepts of porosity and permeability and the importance of these to groundwater storage and movement
11. Define aquifers, aquitards, confining layers, and the differences between confined and unconfined aquifers
12. Explain the concepts of hydraulic head, the water table, potentiometric surface, and hydraulic gradient

PART B: Climate change may bring floods; So now explain some of the steps that we can take to limit the damage from flooding, before and during and after.
