An overview of the fundamental earth science processes responsible for the creation, transformation, and ongoing physical development of western North America. These processes are studied in the context of the building of the North American continent through tectonic forces and surface dynamics. Topics include: geologic time, tectonics, volcanology, seismology, stratigraphy, glaciation, erosion, paleontology, paleoclimatology, and environmental issues. The objective of the course is to familiarize students with the physical environment around them so they may take a more active role in the stewardship of the earth. Field trips and field studies are included.
