An introductory survey of the earth's geologic history from its earliest beginnings to the present, as well as a chronological study of how the processes of Physical Geology have operated, with emphasis placed on the North American continent. Ancient landmasses, ocean basins, mountain ranges, and the development of plants and animals will be among topics discussed. This course is normally taught as a classroom course but in some instances it may consist of an extended field trip to historically important geological regions of the United States or Mexico. In such instances, enrollment will be limited and will require permission of the instructor. Expenses will be shared by the participants. Lab fee. Spring.
