1. Why are streets and highways damaged so much more in the winter months than in the summer months in most of the United States?
2. Sandstones cemented by calcite usually weather much more rapidly than those cemented by quartz. Why?
3. With specific reference to weathering, explain why Egypt is a good location for a monument such as Cleopatra’s Needle, and why New York City is a poor location.
4. The Earth is 4.6 billion years old.  For most of its history, the forces of weathering and erosion have been attacking its surface. Why then do mountains still exist?  Shouldn’t the continents have been worn down flat by now?
5. What are the two major materials of which soil is composed?
6. How are sediments deposited by a glacier different from the sediments deposited by a stream ? (Two differences)
7. Why does one gram of finely ground up salt dissolve quicker than one gram of coarsely ground salt?
8. What two factors does the velocity of a stream depend on?
9. Given a diagram of a meandering stream, you should be able to identify the points of maximum and minimum velocity, where erosion and deposition are greatest, and how the water depth varies at different points across the stream.
10. What effect does stream velocity have on the size of the sediments that can be transported? (As……)
11. You should be able to use the reference tables (page 1 (ruler) & 6(graph)) to determine if a particle is a cobble, boulder, etc.
12. What effect does particle size have on settling time? (As…..)
13. What effect does particle shape have on settling time? (As ….)
14. How will unsorted sediments look after being deposited in water?
