2.  Place the Plot Profile of precipitation transparency over the Plot Profile of topography transparency (make sure it is for the same location!). Answer these questions based on your observations:
 
    a) Is there a relationship between precipitation and elevation?
 

    b) If so, what is the relationship?
 
 
 

    c) What is the reason for the relationship if one exists?
 
 
 
 

3. What is the difference in elevation North to South along longitude 113º west in the state of Montana?
 
 
 

4. What is the difference in precipitation along the same line?
 
 
 
 

5. Why do you think this difference of precipitation exists?
 
 
 
 

6. Generally, in the western states you looked at, the greater the _________ the greater the precipitation.
 
 
 
 

7.  What explanation can you think of where precipitation does not increase with increasing elevation?
 
 
 

8. Can you tell from the precipitation maps, the topographic maps, and the plot profiles which general direction precipitation comes from in these three western states?
 
 
 
 

9. Does the model of increasing precipitation with increasing elevation hold true for the entire United States?
 
 
 
 

10. What factors do you think influence precipitation most in the southeast United States?
 
 
 
 

1.  Which is listed first on the site: to determine the distance, longitude or latitude?
 
 
 

2.  How do you make marks on the map of points that you have found the distances between?
 

3.  How do you keep the image from being enlarged each time you click on it?
