Bachelor of Arts in Earth and Atmospheric Sciences

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 Arts in Earth and Atmospheric Sciences provides a broadly-based background in the fundamentals of Earth and atmospheric sciences. It offers maximum flexibility in course selection to enhance interdisciplinary study and makes a double major easily accessible to students in related fields.


Students must complete 30 credit hours, including the following:

  1. 25 credit hours of courses in the Earth and atmospheric sciences, to include
  2. At least one course at the 100 level, with a maximum of three courses.
  3. At least one course at the 200 level, with a maximum of two courses.
  4. At least one course at the 300 level.
  5. At least one course at the 400 level.
  6. Course work at the 200, 300, or 400 level to reach a minimum of 25 credit hours in Earth and atmospheric sciences.
  7. At least 6 additional credit hours of College of Arts and Sciences courses that carry Natural and Mathematical Sciences distribution credit, chosen from a department or departments other than Earth and Atmospheric Sciences. Students must also complete the requirements and procedures listed in the College of Arts and Sciences Bulletin under “General Requirements for Bachelor’s Degrees.”

Students should note that in many cases credit may only be used for one course in a department if there is significant overlap with another course (e.g. C101 or C105).

The B.A. in Earth and Atmospheric Sciences is designed as a general baccalaureate degree with a science focus. It gives maximum flexibility for students to concentrate on their interests within the major (for example: environmental geology, water quality, economic minerals, materials, petroleum, natural hazards) and seek outside concentrations. It also allows students to pursue double or triple majors. The EAS BA degree requires 25 credit hours in Earth and atmospheric science and 6 N&M credit hours selected from any field, including Anthropology, Astronomy, Biology, Chemistry, Geography, Mathematics, and Physics in any combination and at any level. This easily allows an EAS BA major to apply these 6 credit hours to any elected minor in any of these other fields and to add a major or minor in Earth Sciences to other concentrations. It is also ideal for Pre-Law and Pre-Med students.
