Textbook:

Global Tectonics (2nd Ed.) by Kearey and Vine

Department of Earth and Environmental Science:

Room 133 Life Science, 299-2318

Course Objectives:
We will study the large scale structure and dynamics of the planet Earth and the methods used to study it. The observations that led to the plate tectonic revolution will also be presented.

Earth and Environmental Science Student Lounge:
Check it out. Pell Hall, room 129 E. It's a good place for lunch, studying, etc. There is a microwave, coffee pot, and a refrigerator.

Academic Integrity:
Plagiarism will be dealt with severely. All work presented on exams, homework, and papers must be your own. Any written passages not in your own words must be in quote marks with the source noted. In papers, the source of ideas presented, even in your own words, must also be cited. (see instructions for papers on web site)

Short Papers:
A short paper is required of all students presenting a summary of a scientific journal articles listing the critical points made. The journal article must be approved by Prof. D no later than March 23.  Summary papers must be accompanied by the articles. Papers should be the equivalent of approximately 2-3 pages typed, double-spaced, plus references in a standard bibliographic format, and any figures. Sources must be cited in the body of the paper. (see sources and instructions for papers on web site).  Summary papers are due no later than April 27.

Attendance, tardiness, and class participation will be noted and may affect your grade (for better or worse).

Cell Phones and Pagers:
All cellular phones and pagers must be turned off before entering the classroom.
