Geoscience is a diverse field which focuses on the study of the Earth and other planets and how these systems evolve through time. Geoscientists apply principles of physics, chemistry, biology, and mathematics to understand the evolution of earth history. Geoscientists are employed in environmental engineering, energy, and mining companies; state and federal agencies; and in education, law, and business. The B.S. in Geosciences commonly leads to graduate studies in the physical sciences as well as the STEM MBA. The undergraduate program offers a B.A. in geosciences—geology concentration—and three concentrations in the B.S. degree: geology, geophysics, and environmental geology. Capacity in upper-division GEOL, GPH, and GCH courses may be capped due to limited departmental resources. The residency requirement for the major is 12 hours.
