Question
What seafloor feature is found at location "B" on the bathymetry map of Cortes Bank in Figure 15 (arrow points to feature)? Hint: Note
that this feature has a "bulls-eye"-shaped isobath contour pattern. Check for the change the water depth going from the center of the
"bulls-eye" pattern "outward. VWhere is the shallowest water depth? In the center or towrds the edges of the bulls-eye?
Use the contour
rule to decide on which feature fits the rule.
Choose from one of the following six seafloor features:
Simple slope;
Seamount;
Flat-bottomed basin/trough;
Flat-topped bank;
Submarine canyon;
Submarine ridge
