1. Define the terms "resistance", "resistivity" and "apparent resistivity". In what units is each measured? How is each measured in the lab or in the field?

2. Describe the field procedures of "resistivity profiling" and "resistivity sounding". What are some typical uses of each method?

3. Describe three kinds of resistivity array. What are the advantages and disadvantages of each?

4. Sketch the general appearance of a resistivity sounding curve for each of these situations:..................... Explain each case in physical terms.

5. Compare and contrast the values of a resistivity sounding and a seismic refraction profile for finding water table depth, bedrock depth and sediment type (in New Hampshire, for example).

6. What does the term "equivalence" signify with respect to a resistivity sounding? Explain the physical conditions that lead to equivalence for "H" curves, for "K" curves.

7. What is the meaning of the term "suppression" with respect to a sounding curve? How can we tell if suppression is a problem in any particular case?

8. Explain the basic concept, advantages and disadvantages of each of these methods of analyzing or inverting a sounding curve: empirical correlation, least-squares, Monte Carlo, genetic algorithm, smoothest model, simulated annealing.

9. What is a "resistivity pseudo-section"? How is one made? Why is it useful?

10. What is an "azimuthal resistivity measurement"? How is one made? What is the purpose of such a measurement? How can it be analyzed?

11. What determines the resistivity of most fully or partially saturated rocks and sediments? What is "Archie's Law"? What is it based on?

12. What are the principal conduction mechanisms in rocks and minerals? Give an example of a situation in which each is important.

13. Summarize a resistivity case history that you have read. Discuss the most important things you've learned from your reading.

14. Discuss the problem of "non-uniqueness" of resistivity soundings.

15. Plan a groundwater survey for this situation (......................). Outline the whole project from start to finish. Explain the reason for each step in the project.

16. For this situation and purpose (...................) would you use resistivity or seismic methods? Explain your decision in terms of geological and practical reasons.

17. Explain the least-squares method in mathematical terms.

18. Write an outline for an MS thesis based primarily on resistivity measurements. What would you do? Where? Why would your work be important?

19. How could you speed up the collection of galvanic resistivity surveys and soundings?
