Earth Sciences (BS)

**Effective Fall 2021, the Earth Science major has been renamed to Geosciences with some accompanying changes to the curriculum. As a result, new students can no longer choose the Earth Science major or follow the curriculum below, but can choose to enroll in the Geosciences major. Students already in the Earth Sciences major can continue to follow the curriculum below, or can switch into the new Geosciences major. We encourage students to contact one of our department advisors on the Virtual Advisor to discuss which option makes the most sense for them.
Exceptional students in the Earth Sciences major with an interest in research are encouraged to consider the Scripps Undergraduate Honors Program. Please note that all academic advising questions (for current students) are handled via the Virtual Advisor.
Earth Sciences (BS)
Degree Requirements
Lower-division requirements for all the specializations are designed to provide the foundations in mathematics, physics, chemistry, and biology that are essential in modern quantitative earth science disciplines. All Earth Science majors take an introductory course: SIO 50, and four upper division core requirements introducing basic concepts in the Earth Sciences. SIO 100, SIO 102, SIO 103, and SIO 104. Ideally, SIO 50, SIO 100, SIO 102, and SIO 103 should be taken during the sophomore year to provide the appropriate background for other upper-division courses.
It is strongly recommended that all Earth Science majors meet regularly with the Earth Science program academic advising staff and a faculty adviser to discuss and update curriculum choices.

An Earth Sciences major is good preparation for students who are considering K-12 science education and/or public education and outreach as a career. Students with these interests should consider the academic minor in science education, offered through the Department of Education Studies, as a complement to the Earth Sciences major.
