WVU GEOLOGY/GEOGRAPHY 321 TEST I
J. Steven Kite, 9 Feb 2006

The essay: Answer on your own paper

1.  What are the most important roles that water plays in chemical weathering, physical weathering, and slope stability? (25 % of the test grade. Budget no more than 20-25 minutes for this question..  Answers must be legible and limited to 1 page (1 side of a sheet of paper). Nearly half of the basis for grading will be for “communication,” including completeness, accuracy, clarity, writing style, and use of correct grammar.)

2. Definitions (3 pts each)

5. What is tectonic denudation’ as described by Bloom (2004, p. 77-78)?  What is the geological outcome of tectonic denudation? (i.e. What would the geology be after tectonic denudation)?  (6 pts)


6. Why is agricultural fertilization of limited benefit in Oxisols? (6 pts)

 

 

 

 

 

 

 

 

 

 

 

 



7. How does the depth and character of weathering vary in relation to latitude (and climate).  Begin your discussion with weathering in the tundra and work through mid-latitude forest, deserts and semi-arid lands and end with the tropics. (Bloom p. 140-141; 6 points)
