Name __________________ WVU GEOLOGY/GEOGRAPHY 321 TEST I J. Steven Kite, 12 Feb 2009 I. Definitions (3 pts each) 1. Dynamic equilbrium 2. Avalanche 3. Cumulic Haplustoll: 4. Half Graben: 5. Chelation II. MULTIPLE CHOICE QUESTIONS (2 pts each) Circle the letter in front of the correct answer. 6. What is the missing component of the following equation for the weathering of orthoclase to kaolinite: 2KAlSi3O8 + 2H2CO3 + 9 H20 = Al2Si2O5(OH)4 + 4 H4SiO4 + 2K+ + ??? : (A) H2O, (B) 2HCO3-, (C) HCO2-2, (D) 2H2CO3, or (E) HCO3-. 7. A Geomorphic system with a delicate balance between gains and losses of energy and matter over time is (A) isolated, (B) closed, (C) static, (D) metastable, or (E) graded. 8. What morphometric variable can be used to differentiate fault-block tectonic landscapes that are actively faulted from those in which faulting has long ceased? (A) Presence vs. absence of alluvial fans, ( B) total topographic relief, (C) mountain-front sinuosity, (D) stream channel sinuosity, or (E) presence vs. absence of slickensides on fault surfaces. 14. Discuss how the dominant types of weathering (physical vs. chemical) vary under the different temperature and moisture conditions found in different climates. A figure may help, but your answer must include sufficient text to explain the figure (9 pts.) 15. Describe a cinder cone and the process that lead to development of cinder-cone volcanoes, including discussion of magma type and consistency. (9 pts) 16. Explain the structure of the 2:1 clay illite (= muscovite). Illustration may help, but answer the question in complete sentences? (9 pts) IV. The essay: Answer on your own paper (25 pts: 13 for content, 12 for communication). 17. What is the Coulomb equation and how can it be used to determine slope stability? What is the role of pore pressure in the Coulomb Equation and slope stability? Name __________________ WVU GEOLOGY/GEOGRAPHY 321W TEST I J. Steven Kite, 12 Feb 2009 Write a typed, spell-checked, and proof-read ~1000 word response in the next 75 minutes. E-mail the file to Dr. Kite in Word 1997-2003 format. Its name must follow a GEO321yourname_assignment_draft# format (e.g. GEO321Kite_Paper1_Draft1.doc). Use at least ¾ inch borders and 12-point type in an easy to read font, such as Times New Roman or Arial. Double space the text and number the pages. What is the Coulomb equation and how can it be used to determine slope stability? What is the role of pore pressure in the Coulomb Equation and slope stability?   This draft response will be graded and returned for revision and expansion to 6-8 pages. The whole iterative writing assignment constitutes 20 % of your 321 grade. (Your rough draft today = 3 %, your second draft = 5 %, peer review of 2 other students’ papers = 4 % [2 % each], final grade on papers you peer reviewed = 2 % [1 % each], final grade on your paper = 6 %).   The two 6 to 8 page writing assignments will be evaluated using the following benchmarks: 90 (A+): The paper is outstanding in organization, content, clarity, grammar, and structure. Scientifically accurate, thorough, and well reasoned, the paper is written with flair, but in a style appropriate for scientific literature. Free of misspellings and inconsistencies, from abstract to references cites there is little room for improvement. 80 (A-): The paper is excellent, except for possibly one area, in organization, content, clarity, grammar, and structure. Scientifically accurate, thorough, and well reasoned, the paper is written in a style appropriate for scientific literature. There are few missed punctuations, misspellings, or inconsistencies. 70 (B): The paper is easily understood, except for minor flaws in organization, content, clarity, grammar, or structure. Scientifically accurate and well reasoned, the paper is written in a style appropriate for scientific literature, although the references cited to back important points may have been insufficient or inappropriate. Paper needed better proof-reading to avoid missed punctuations, misspellings, or inconsistencies. 60 (C): The paper can be understood satisfactorily, in spite of flaws in organization, content, clarity, grammar, or structure. Scientifically accurate throughout most of the paper, it is well reasoned in some sections. The paper may not be written in a style appropriate for scientific literature, or the references used to back the points of the paper may have been insufficient or inappropriate. Paper needed more proofreading to avoid missed punctuations, misspellings, or inconsistencies. 50 (D): One or more of the following faults occur in the paper: It is difficult to understand because of significant flaws in logic, organization, content, clarity, grammar, or structure. It is scientifically inaccurate throughout much of the paper. It is poorly reasoned in significant sections or written in a style inappropriate for scientific literature. References cited are insufficient or inappropriate. Paper needed more proof-reading to avoid obvious missed punctuations, misspellings, or inconsistencies. 40 (F+): Several of the following faults occur: The paper is almost impossible to understand because of significant flaws in logic, organization, content, clarity, grammar, or structure. It is inaccurate or poorly reasoned in significant sections. The paper is written in an unprofessional or inappropriate “style” for non-fiction literature. References cited are lacking, inappropriate, or likely the first thing that appeared in a Google search. Paper appears not to have been proof-read and writer may have been so lazy as to expect the instructor or peer reviewers to write the paper.
