Program Overview

Earth and Planetary Sciences Major

The Earth and Planetary Sciences major is designed for students interested in highly interdisciplinary science addressing many of the most profound issues facing the world in the 21st century. The major builds knowledge and skills relevant to further studies of, and/or careers in, geology and geophysics as well as environmental science, with specific emphasis on areas of relevance to humans such as climate change, sustainability, geohazards, and renewable energy.

Honors in Earth and Planetary Sciences

• Majors with strong academic records and an interest in pursuing honors should discuss possible research projects with a faculty member and/or the director of undergraduate studies (DUS) early in their undergraduate career, but no later than spring quarter of their junior year.
• After the faculty mentor approves a proposed project, research is conducted and students must complete at least two credits of EARTH 399-0 Independent Study with the academic advisor of their project; only one EARTH 399-0 credit may count towards major requirements.
• To earn the honors distinction, students must complete a thesis following the guidelines published on the department webpage.
