Hypothetical Landmass

Hypothetical Landmass

Create a landmass of your own imagination with reference back to the earth science/geological concept of the supercontinent of Pangaea.

Draw a map of the landmass. Given the orientation of the landmass, create currents around the landmass using all of your understanding of what creates currents.
Is the landmass in the northern or southern hemisphere?
Are there any bays/inlets that might create significant tidal changes that would affect currents?
Is the rest of the planet water or are there other landmassess, ice caps, etc?
What seasons does the landmass have (keep in mind the tilt of the planet)?

After you create your landmass and determine answers to the above questions, your group needs to create a presentation addressing the four points below. You will be assessed using the Ocean in Motion Project Rubric. Your presentation should address the following:

  • Which factors driving and directing currents (wind, tides, density (salinity/temperature) and topography) pertain to the new landmass? Why?
  • Were humans affected by currents, and if so, how?
  • How does the weather in the area of the landmass affect the currents?
  • What technology pertains to studying the currents in the area of the landmass?
