Variations

This chapter uses the Atlantic Ocean as an example, yet a similar activity could be focused on any other ocean or landmass.

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.
