[Look at questions in the back of the relevant chapters; look at the web notes and your lecture notes. Note that all matching questions have the exact number of questions as answers, and none are used twice. If you think about it that means that you only have to know 4 of 5 to get the correct answer for the fifth answer. Some answers require simple sight recognition, others are more difficult. You may have to look at the logic of the statements to see if you can eliminate among the impossible answers, then think more carefully about the remaining answers.

How do slides and flows differ?

1. A. Slides travel farther and faster than flows.
2. B. Flows are lubricated by water, but slides are not.
3. C. Slides have coherent internal movement and flows, chaotic.
4. D. Slides typically involve much larger volumes of material than flows.

Longshore transport is dependent on

1. A. the angle at which the wave front approaches the beach

5. E. a source of conglomeratic material

The primary determinant of whether coastal erosion or deposition takes place is

1. A. the way wave energy is released on beach
