Quiz #4 will consist of 15 questions to be answered during the first 30 minutes of class on 23 March. The questions will be short answer, fill in the blank, label the diagram, or draw a diagram. The quiz is worth 50 points. We will have an informal review on Wednesday evening (3/22) starting at 8:00 PM in room 142. The Geoscience Club is also having their tutoring sessions on Tuesday from 7:30 - 9:30 PM and Wednesday from 8:00 - 9:00 PM in room 138. Also remember that I may draw questions from previous quizzes or exams.
