Earth & Environmental Science

B.A. in Geology

Geology is the scientific study of the materials and resources that make up the Earth; the internal dynamic processes that move continents, build mountains and cause earthquakes; the surface processes that sculpt the landscape, shape river valleys, erode coastlines, and drive ocean circulation; the natural hazards posed by geologic processes; and the history of the Earth, its changing climate, and life on Earth.

Geologists work for universities, government agencies and private firms studying energy and mineral resources, groundwater and surface water resources and threats to water resources, hazards from earthquakes, volcanoes, landslides, river and coastal flooding, Earth’s climate history, and the effects of climate change.

The 129-credit Bachelor of Arts in Geology program provides the essential core knowledge for careers in the geological and environmental sciences while allowing students some flexibility with electives to follow their interests in completing their program of study. Students who earn a geology degree will also have completed the science requirements for certification to teach Earth Science (see the College of Education, Information & Technology for other requirements).
