  • Complete using your textbook to find answers to the following questions.  Next week we will spend going over this information and answering any questions that come up.  Good luck and have fun!  Be sure to look at the grading criteria before and during your work.

Outline Grading Criteria:

  • Outline shows a conscientious effort to be complete and explain the questions posed.  Most answers are correct.


  • Student shows depth of answers by explaining, defining, and giving examples where appropriate.  If there is a sentence or less for each question, this grading criterion is not met.

b)     What is the Wild and Scenic Rivers Act of 1968?



c)      Using the evidence your book gives, is tapping a) renewable and b) nonrenewable groundwater supplies an appropriate way to solve this problem?



d)     Using the evidence that you book gives, is desalinizing water a feasible way to provide water for people?
