Using the graph below, construct a topographic profile from Point “A” to Point “B.” Plot the index contours, as well as the crest and bottom of the fault scarps. The vertical exaggeration of the profile is approximately 6.7x.
The question is based on the “Mt. Dome, California” quadrangle (Map T-24; enlarged to scale 1:48,000; contour interval 40 feet). Three prominent fault scarps can be seen running north to south across the map, and will be referred to as the “western” fault, the “central” fault, and the “eastern” fault. These faults scarps are the result of normal faulting. Figure 36-5 is a stereogram of the same region (in Figure 36-5, north is to the left side of the page). Hint: Because the contour lines are very close together, it may be difficult to discern the elevation of the top and bottom of a scarp. To determine these elevations, find an index contour in the gently sloping area between two scarps, and then count the number of contour lines to the top or bottom of a scarp.
You are exploring an ocean basin and trying to determine whether it formed by sea floor spreading. Which of the following evidence would you NOT expect to find in an actively spreading ocean?
