Copper atoms have a greater tendency to be reduced than iron atoms do. Was this good news or bad news for the Statue of Liberty, whose copper exterior was originally held together by steel rivets?
A. This was good news since the steel rivets prevented the copper from eroding. B. Electrons will preferentially flow from the iron to the copper and then onto oxygen. Corrosion is thus accelerated around the interface of these two metals. C. This combination of metals caused the copper to oxidize and turn green. D. This combination of metals has no effect on each other and that is why engineers chose to use them together.
What might explain this variation in scarp height?
The following questions are based on the “Mt. Dome, California,” quadrangle (Map T-24; enlarged to scale 1:48,000; contour interval 40 feet) and the stereogram of the same region (Figure 36-5; north is to the left side of the page). 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 fault scarps are the result of normal faulting (41°49'39"N, 121°33'15"W). What will be an ideal response?
