Bachelor of Arts in Earth and Atmospheric Sciences

Students on Summer 2020, Fall 2020, or Spring 2021 requirements EASBA

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.


The major requires at least 30 credit hours (36 with the Addenda requirements), including the requirements listed below.
  1. Introductory Course. One (1) course:
    • Any EAS-A 100–199
    • Any EAS-E 100–199
    • Any EAS-X 100–199
  2. Intermediate Course. One (1) course:
    • EAS-E 225 Earth Materials
    • EAS-E 226 Earth Processes
    • EAS-E 227 Earth Climate and History
    • EAS-E 271 Introduction to Environmental Field Methods
  3. Advanced Courses.
    1. 300-Level Course. One (1) course:
      • Any EAS-A 300–399
      • Any EAS-E 300–399
      • Any EAS-X 300–399
    2. 400-Level Course. One (1) course:
      • Any EAS-A 400–499
      • Any EAS-E 400–499
      • Any EAS-X 400–499
  4. Electives. Additional courses, as needed, to fulfill remaining requirements.
    • Additional course from the Intermediate Course list
    • Additional course from the 300-Level Course list
    • Additional course from the 400-Level Course list
  5. Addenda Requirement*. Six (6) credit hours:
    • Any non-EAS course that carries CASE N&M credit
  6. Major GPA, Hours, and Minimum Grade Requirements.
    1. Major GPA. A GPA of at least 2.000 for all courses taken in the major—including those where a grade lower than C- is earned—is required.

    3. Major Upper Division Credit Hours. At least 18 credit hours in the major must be completed at the 300–499 level.
    4. Major Residency. At least 18 credit hours in the major must be completed in courses taken through the Indiana University Bloomington campus or an IU-administered or IU co-sponsored Overseas Study program.
    5. College Breadth. At least 58 credit hours must be completed in courses from College of Arts and Sciences disciplines outside of the major area.
