For any lines you plot and graph, consider what the graphic representation actually means about the seafloor.
- What do the high and low points along your graph mean?
- Does your profile represent the actual shape of the seafloor? Discuss how the profile is similar to and different from the seafloor it represents.
- From a single profile, what can you infer about the three-dimensional shape of any ocean basin?
- Compare profiles you create with the Atlantic and Pacific profiles that appear within this chapter.
