Question 1

Which of the following statements is FALSE?

Not all rocks can be dated radiometrically.

Fossils are used to correlate sedimentary rocks that are widely separated by using the rock's distinctive fossil content and applying the principle of fossil succession.

A stable radioactive isotope, called the parent, will decay and form daughter products.

During the seventeenth century, Catastrophism influenced the formulation of explanations about the Earth.

Question 21

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.")

Question 22

Volcanoes are generally not preserved in the geologic rock record as they are usually eroded away. However, the various materials erupted from volcanoes are often found preserved in the rock record. From what you have learned about the different types of volcanoes, how could you infer what type of volcano erupted in a given area based on the type of volcanic deposits now found as layers of rock? Give specific examples, and briefly discuss how some materials may be linked to different types of volcanoes.

Question 23

What are the different types of seafloor sediments, and what are the factors that control the distribution of each major sea sediment type? Where does each major seafloor sediment type tend to accumulate in greatest quantity (i.e., discuss the distribution of these sediments)?

Question 24

Shorelines are temporary geologic and topographic features. Explain this statement. (Hint: what are some of the forces affecting both the erosion and deposition of materials? What are some common temporary shoreline features - both erosional and depositional?)
