The Earth Sciences major includes a spectrum of disciplines focused on understanding the processes that influence the tectonics and environment of the planet, on using this understanding to read the record of earth history written in rocks and sediments, and on developing models that can be used to predict future changes due to natural phenomena and recent perturbations caused by humans. Issues of societal concern related to seismic risk, climate change, environmental contamination, and other geologic hazards play an important role. The department is affiliated with two research centers: the Southern California Earthquake Center and the Wrigley Institute of Environmental Studies. The B.A. degree is recommended for students interested in the Earth Sciences but who intend to pursue careers in other fields, such as business, law, or education.
