When you are finished with this topic, you should be able to answer the following questions:

  1. What types of stress are associated with each of the three faults?
  2. Folds are formed by what type of deformation and stress?
  3. What is the difference between a joint and a fault?
  4. How do you distinguish between a right-lateral and left-lateral strike-slip fault?
  5. What type of fault would you expect to be predominant at each type of plate boundary?
