Satisfactory scores in the Chemistry and Mathematics Placement Examinations are required for Chemistry 101, Mathematics 255A, and Physics 100A, all of which are part of the Geology major. Students not having this preparation will need additional coursework in deficient subject areas. A minor in Geology is designed for students interested in Earth, but with a major in another department. Biologists, engineers, mathematicians, and physicists are finding employment in the environmental and energy-related industries. For these majors the Geology minor broadens the individual's background and competence in the Earth sciences.
Geologists study the structure, composition, and history of Earth's crust.
By examining surface rocks and drilling to recover rock cores, they determine the types and distribution of rocks beneath Earth's surface. They also identify rocks, minerals, and fossils, conduct geological surveys, draw maps, take measurements, and record data. Geological research helps to determine the structure and history of Earth and may assist in predicting future geological events, such as earthquakes, volcanic eruptions, and landslides. A second important aspect is protecting our geological environment from pollution. Geologists use many tools and instruments, ranging from simple hammers, levels, compasses, and cameras, to more sophisticated equipment such as surveying instruments, gravity meters, and seismographs.
