Bachelor of Science in Earth Science

Notice: The information on this page is for informational purposes only, and does not necessarily reflect official degree requirements, which can change. Students should refer to the degree requirements for their matriculation term in the official College of Arts and Sciences Bulletin, and consult with the academic advisor.

The Bachelor of Science in Earth Science provides training for those who want to become professional geologists and seek careers in the application of earth sciences to the minerals, energy, and environmental industries as well as federal and state agencies, research laboratories, and postsecondary education.


Students must complete the following fundamental skills and distribution requirements:

  1. Writing, same as B.A. degree.
  2. Foreign language, 3 credit hours at the second-year level or competency equivalent via placement exam, reduced by one course from the B.A. requirement.
  3. Arts and humanities, two courses, reduced from four courses for the B.A.
  4. Social and historical studies, two courses, reduced from four courses for the B.A.
  5. Natural and mathematical sciences, fulfilled by major.
Major Requirements

The requirements for the major are:

  1. Any one formal 100-level course in the Earth and Atmospheric Sciences. EAS E111, EAS E112, or EAS E104 is recommended.
  2. EAS E221, EAS E222, EAS E323, EAS E334, and EAS X429.
  3. Three formal 3 or 4 credit hour Earth sciences courses at the 400 level.
  4. Chemistry C117; C118 is recommended.
  5. Mathematics M211 and M212.
  6. Physics P221 and P222.
  7. Biology L111 or L112.
  8. Two courses at the 300 or 400 level, intended for science majors, selected from Biology,
    Chemistry, Physics, or Mathematics. Recommended courses include Biology B300
    or Z374; Chemistry C360 or C361; Mathematics M311 or M343; and Physics
    P331 or P340. These courses must be selected from two different departments.
  9. One additional formal 3 credit course at the 300 or 400 level from any of the following
    departments: Biology, Chemistry, Mathematics, or Physics, or one additional
    formal 3 credit Earth and Atmospheric Sciences course at the 400 level.

Students should satisfy the 100- and 200-level allied sciences and mathematics requirements at the earliest possible date.

Popular TFR (topics) classes in the Earth and Atmospheric Sciences include: EAS E121 Meteorites and Geological Processes in Planets, EAS E141 Earthquakes and Volcanoes, and EAS E188 Volcanoes of the Eastern Sierra Nevada

The B.S. degree in Earth Sciences is designed to prepare students to become professional earth scientists, as well as to attend graduate school for further advanced training. We require 39 credit hours of Earth science courses including field training in Montana (EAS X429). We also require 32 hours of course work in closely related Allied Sciences and Mathematics (AS&M), including course work in each of chemistry, physics, and math. Many students elect to apply these credits toward a minor in these fields. To allow maximum flexibility and specialization within the earth sciences (e.g., environmental geology, mineralogy, petrology, geochemistry, economic geology, petroleum geology, geophysics, paleobiology, astrobiology, planetary science), 400-level course work in Earth Sciences, and all 300 and 400 level course work in allied sciences is not specified
