What type of slope angle does the seafloor have at location "C" on the bathymetry map of Cortes Bank in Figure 15? Hint: Note that
this region of seafloor has a set of parellel-oriented isobath contours with a certain relative spacing between isobaths. Is that spacing very
tight together, moderately-spaced, or widely spaced? Study the entire map to get a sense of distance between isobaths to get a sense of
tightly-spaced versus widely-spaced isobath line. Use the contour slope rule to figure out slope angle.
Choose one of the following:
Steeply-angled slope;
Moderately-angled slope;
Gradually-angled slope;
No slope = totally flat seafloor
