With the formation of Pangaea, disconnected
Chapter 23, Problem 34(choose chapter or problem)
With the formation of Pangaea, disconnected continentsmerged into one huge landmass. This decreased theamount of shallow marine environments, which led tomass extinctions during the Permian. Let us compare thedifference in coastlines for a single large landmass and asame-sized landmass that is broken up into several pieces.(a) Find the perimeter for each shape shown here. Thenadd all the perimeters together.(b) Like Pangaea, the shapes are joined into one landmass.Find the perimeter of the single landmass.(c) Compare the the total perimeters for parts a and b.Do your results support the decrease in coastlines afterthe formation of Pangaea?
