Review sheet for Midterm Examination (to be given 5 March)
GEL/ESC 1300G

The midterm examination will consist of 40-50 questions to be answered during the 50 minutes of class on 5 March.  The questions will be short answer, fill in the blank, label the diagram, or draw a diagram.  The examination is worth 100 points.  The examination is cumulative, but will emphasize material coverd since the last quiz.  We will have informal reviews on Thursday (3/4) evening starting at 5:30 PM in room 3120.  Wednesday (3/3) we will have a review in class for the midterm.  The Geoscience Club is also having their tutoring sessions on Mondays and Thursdays from 8:00 - 9:00 PM in room 1060.  Remember that I may draw questions from previous quizzes.
