Stable craton is when the two continental tectonic plates are fully stick together, also expanding the ocean basin that is located on the east side. At the new continental plate, mountains are eroded to sea level and the tectonic plates are stable once again

Lab 10 Part C: Wilson Cycles of the Past

Question C.1:

Reflect on the knowledge you have obtained in previous labs and in the beginning of this lab to predict what the major tectonic plates (and their associated continental landmasses) will look like at the end of the current Wilson Cycle, about 300 million years from today.

Hand-draw and then photograph (or scan) your final results, or you may attempt to create your answer entirely in a graphic program. Either process is acceptable, as long as the final result is neat and organized, and “inserted” into the final document you upload in Blackboard.

Show only the final representation of what you think the Earth will look like in 300 million years. Use Video 02 to estimate the magnitude of motion and the types of motion that you could expect.

Your final product should show a project of the whole Earth (the horizontal ellipse) similar to what was shown in Video 02.

➔ North America should be “centered” in the middle of your Earth representation (e.g., in the middle of the ellipse, with the other land masses arranged around it based on your hypothesis).

Your final drawing should be no smaller than 8.5” x 11” (a full single page), and should include a description and labels of what is drawn.

You final drawing must also include “basic” outlines of the major global continents and/or countries (as seen as the thin black lines in Video 02).

Question C.2:

In 5-7 well-written complete sentences, describe the motion of the major tectonic plates (and their associated continental land masses) that you used to make your prediction in Question C.2.

The reason of why my sketch looks like in the picture above in 300 million years is because in the beginning of the second video, it started as most continent are located in the south of earth and throughout many years they have been getting separated into continents that we know now, however, in this lab it was mentioned that tectonic plates are always in movement even if it is 1 cm per year, but it still moving, and also if the continents are can get separated, why can’t they get back together again since earth is a spherical planet. So by following the movement of the plate in the video 2, I imagined that the continents would get back together again as the continents gets closer and closer together looking like the picture above.
