3. (1 pt) What is the contour interval on Map 3 above? AB 900 feet 800 feet Drumlins |+++ 1000 feet Map 3. 4. (1 pt) What is the regional relief on Map 3 above? 5. (1 pt) Using the contour lines on Map 3, which area along the red line is steeper- A to B or B to C? Explain how you came to this conclusion. 6. (2 pt) What is the gradient from A to B and B to C on Map 3? Show your work. 7. (2 pt) Drumlins can be used to determine the original direction of flow in a glacier, with the glacier originally moving toward the shallower side of the structure and then retreating in the opposite direction (see illustration below). Using your previous answers from Questions 5 and 6 above and the illustration below, what direction was the glacier traveling originally traveling, before it retreated? Explain your answer.
