California State University

What you'll study

The programme covers the major subdisciplines of Earth science, with a balance of theory, laboratory methods and fieldwork. Core topics typically include mineralogy and petrology, structural geology, sedimentology and stratigraphy, paleontology, geochemistry and geomorphology. Students take quantitative courses such as introductory calculus, statistics for scientists and physics, and apply these to Earth-science problems.

• Laboratory and practical skills: rock and mineral identification, thin-section petrography, geochemical analysis, geochronology basics.
• Field methods: mapping, stratigraphic logging, field sampling, structural measurement and field safety—often culminating in multi-day field trips or a field camp.
• Computational tools: GIS and remote sensing, basic programming or data analysis for geoscience datasets, and modelling of geological processes.
• Applied topics and electives: hydrogeology, environmental geology, geophysics, engineering geology, natural hazards and resource geology.
• Capstone and research: senior thesis, laboratory research project or applied capstone with an industry or agency partner to synthesise knowledge and demonstrate professional skills.

Entry requirements

Entry is at undergraduate level and applicants are expected to have completed secondary education equivalent to a high-school diploma. Successful candidates typically demonstrate a strong foundation in maths and science—especially algebra, geometry, precalculus or calculus, chemistry and physics. Admissions assessments consider academic record, personal statement and any relevant extracurricular or work experience.

Specific campus-based requirements vary across the California State University system: some campuses may expect particular course prerequisites, a minimum GPA threshold or placement testing in mathematics. Applicants with prior college credit, AP/IB scores or transfer qualifications should check the campus programme page for articulation details.

Career prospects

Graduates with a bachelor’s in Geological and Earth Sciences go on to a wide range of careers. Typical early-career roles include geological technician, field geologist, environmental consultant, GIS analyst, hydrogeology assistant and laboratory technician. With additional training or experience, graduates move into positions in mining and resource exploration, geotechnical and civil engineering support, oil and gas industry roles, environmental remediation and water-resource management.

Other pathways include employment with federal, state and local agencies (for example in natural hazards, land management or water resources), roles in environmental permitting and compliance, and continued study at graduate level for research or academic careers. The programme also provides transferable skills—data analysis, project management, scientific communication and field safety—that are valued in many sectors.

Why study at California State University

Studying Earth sciences within the California State University system gives students exposure to an exceptionally geologically diverse region, from coastal settings and mountain ranges to deserts and volcanic terrains—ideal for field training and applied projects. CSU campuses emphasise hands-on learning, with laboratory facilities, field courses and internship links to industry and government agencies.

Faculty in CSU geology and Earth-science programmes commonly engage in applied research and community-focused projects, offering opportunities for undergraduates to participate in real-world studies. In addition, the system’s focus on accessibility and affordability, campus career services and partnerships with regional employers help students obtain practical experience and graduate into the workforce or graduate study paths.
