A team-taught introduction to geology that emphasizes the physical processes affecting the earth. The first seven weeks introduce the fundamental topics, such as rocks and minerals, volcanoes and earthquakes, plate tectonics and mountain building. The second seven weeks will vary in content, covering topics such as planetary geology, the earth's interior, or environmental geology, depending upon the instructor. Labs and field tripswill be integrated into projects involving the solution of geological problems of the local area. No prerequisites. Includes one 1.5-hour laboratory per week. Open to freshmen and sophomores; juniors and seniors admitted by permission of instructor if class space is available.

215. EVOLUTION OF THE EARTH

The history of the earth and the life upon it, from theorigin of the planet 4.5 billion years ago to present. After covering the basic principles of interpreting earth history, the course will survey such topics as the origin and evolution of life, interpretation of ancient environments, mass extinctions, hot-blooded dinosaurs, the Ice Ages, and the future of humans on the planet. Two field trips, including an extended trip to the Grand Canyon and Zion National Parks. Includes one 1.5-hour laboratory per week. Prerequisite: Geology 105 or permission of instructor.

315. SEDIMENTARY GEOLOGY

Study of the processes of sedimentation, and the interpretation of sedimentary rocks as tools in determining ancient environments and geologic history. The use of stratified sedimentary sequences for correlation, dating, and determining tectonic history. Three field trips to interpret ancient sedimentary sequences. Includes one 1.5-hour laboratory per week. Prerequisite: Geology 215, 335, or permission of instructor.

365. PALEONTOLOGY

The evolution and paleobiology of animal life as shown by the fossil record. Lectures will emphasize the methods used to interpret the fossil record, and cover topics such as ontogeny, speciation, phylogeny and systematics, functional anatomy, biogeography, paleoecology, and macroevolution. Laboratories will focus on paleobiological principles that can be demonstrated by the major groups of vertebrates and invertebrates. Includes one 1.5-hour laboratory per week, and two field trips to collect and interpret fossils and the environments in which they occur. Prerequisite: Geology 215 or Biology 279, or permission of instructor.
