1. Discuss the geologic history of the area where you live or grew up. Discuss some of the major factors that might have played a role in shaping the local terrain (major rivers, sea-level changes, volcanoes, ancient sea beds, glaciers, earthquakes, etc.). If needed, spend a few minutes researching your state on-line, (search for your state and "geologic history"). Be sure to list all sources that you use in your answer.
2. According to the figure below, give an approximate age for the Dakota Sandstone and for the Wasatch Formation. Explain what evidence you used to determine this.

3. Recall from reading the nature of volcanoes, and in your own words, briefly discuss how the rate of cooling determines the type of rock that forms from magma/lava.
4. Recall from your reading about the nature of volcanoes, and in your own words, compare and contrast aa and pahoehoe lava in appearance and how they form.
5. In your own words, discuss volcanic hazards. Although commonly thought to be associated with most volcanic eruptions (by the general public), lava is rarely responsible for the loss of life. Which hazards would tend to be more deadly? Finally, indicate and discuss those hazards that are a direct result of a volcanic eruption as well as those hazards that are indirectly linked. (Hint: think of "indirectly associated" hazards as "side effects".).
Your response should be at least 200 words in length.
