For this section, you had to look at Figures 1 and 2 and try to figure out the order in which rock layers were laid down. The patterns in the rectangles which represent different rock layers were significant, meaning that if you saw the same pattern in two different rectangles in two different outcrops, you were seeing the same rock layer. I built the figures that way so that you could work out the relationship in age from one layer to the next.
