Answer to Question 1

B

Answer to Question 2

Though this is considered a learning objective of this chapter, it is not fully discussed in this edition of Geosystems. Figure 12.13 nicely illustrates it, showing the pre-Pangaea configuration, and moving through the formation of Pangaea some 225-200 mya, and its eventual break-up.
