Ch. 22.5 Faults & Folds Self Quiz Look at each image and interpret the faults and folds. Answer questions in your notebook or a separate piece of paper. 1. What type of fold is shown here? (Anticline or Syncline) 2. Would these folds be created in a DUCTILE (high temp. & pressure, deeper in crust) or BRITTLE (low temp & pressure, at surface) environment? 3. These folds in Newfoundland New Jersey would have be produced … a. b. c. d. When Pangaea assembled ~ 240 Ma. When Pangaea broke apart ~ 100 Ma During the ice age as glacial ice sheets retreated ~ 10 Ka They are currently being produced by New Jersey’s current tectonic activity. 4. Support your answer to #2 with a reason. 5. Is this a dip-slip or strike slip fault? If dip-slip – say what type of dip-slip (Thrust or Normal). 6. Is this fold produced by compressional; extensional; or shearing forces? 7. What type of plate boundary would you expect to find these faults? (Convergent; Divergent; Transform) 8. Which fault would be produced by shearing forces? 9. Would fault H be made in an ancient rift valley or a mountain building zone? Support your answer with a reason. 10. A. What type of fault can you see in this picture ? B. Could this location be an ancient subduction zone? Why or why not? 11. A. What type of fault can you see in this picture ? B. What type of plate boundary produces these faults? 12. A. What type of fault can you see in this picture ? B. Could this location be an ancient convergent plate boundary? Why or why not? 13. A. What type of fault can you see in this picture ? B. What type of forces produced this fault? (There are 2 forces)
