All answers and proper figures should be done CQC (Complete, Quality, Correct) on your own paper.

Write complete sentences and incorporate the question in your answer.

a. What drives the internal forces on Earth?

 

b. What drives the external forces on Earth?

 

 

2. (Properties-->Geology-->Formation of Puget Sound) (15 pts)

 

a. Why is Puget Sound an estuarine fjord?
