Scientific research supports the existence of Alfred Wegener's proposed supercontinent, Pangaea, approximately 300 million years ago. Pangaea subsequently broke apart, and the piecesour modern continentsmigrated to the positions they occupy today.
 
  Based on your knowledge of the mechanics of tectonic motion, do you think there is a likelihood of another supercontinent forming? If so, where?
  What will be an ideal response?

Answer to Question 1

Answer: The break-up of Pangaea led to the creation of the Atlantic Ocean. The divergent plate boundary that exists today is still spreading, enlarging the basin and pushing North America, South America, Europe, and Africa farther apart. As this basin grows, the Pacific Ocean basin shrinks due to the convergent plate boundaries around the margins of the Pacific plate. Recent studies indicate that the North American and Eurasian continents will meet over the North Pole, though it would be reasonable for students to suggest that the next supercontinent would form in the Northern Pacific.

Answer to Question 2

Answer: B
