Geology major
Geology: courses, careers, and where to study
Geology studies the Earth's materials, structure, and history, suiting students drawn to fieldwork, lab analysis, and questions about natural resources, hazards, and deep time.
A Geology major covers mineralogy, petrology, structural geology, sedimentology and stratigraphy, paleontology, geochemistry, and geophysics, built on a core of chemistry, physics, and calculus. Most bachelor's programs include a required summer field camp where students map rock units and structures in the field, plus lab work with rock and mineral samples, thin sections, and geologic maps. Many programs let students lean toward a track such as environmental geology, hydrogeology, economic/resource geology, or geophysics.
Graduates work in environmental and geotechnical consulting, energy and mineral exploration, water-resource management, hazard assessment (earthquakes, landslides, volcanoes), and government surveys such as the USGS and state geological surveys. The work typically combines field data collection, sample and instrument analysis, and GIS-based mapping and modeling.
The U.S. Bureau of Labor Statistics reports a 2024 median annual wage of $99,240 for geoscientists, except hydrologists and geographers, with a bachelor's degree as the typical entry-level education and projected employment growth of 3.2% from 2024 to 2034. Some research and senior roles favor or require a master's degree, and several states license practicing geologists.
Academic classification (CIP)
In the federal Classification of Instructional Programs, Geology maps to CIP 40.0601, Geology/Earth Science, General, within the PHYSICAL SCIENCES family. The official definition:
A program that focuses on the scientific study of the earth; the forces acting upon it; and the behavior of the solids, liquids and gases comprising it. Includes instruction in historical geology, geomorphology, and sedimentology, the chemistry of rocks and soils, stratigraphy, mineralogy, petrology, geostatistics, volcanology, glaciology, geophysical principles, and applications to research and industrial problems.

What credential Geology is awarded as
Of the 5,691 Geology credentials U.S. colleges reported conferring in 2023-24:
- Certificate<1%35
- Associate2%131
- Bachelor's67%3,832
- Graduate30%1,693
This mix is fairly consistent nationally: across the 33 states reporting it, the certificate share moves by about 3 percentage points between the 10th and 90th percentile state, so the credential is more a property of the field than of where you study it. See the full study.
Credentials conferred in 2023-24, U.S. Department of Education IPEDS completions. A certificate is a different credential from a degree, not a lesser one, and this counts what was awarded rather than what a college currently offers.

Crosswalk: U.S. Department of Education (NCES), CIP 2020 to SOC 2018. Pay, openings and projections: U.S. Bureau of Labor Statistics (2024 wages, Employment Projections). 5 of these 5 occupations report a median wage.
“Most entrants hold” is what BLS observes about people already working in the occupation. It is not a legal requirement, not an admission rule, and not a guarantee of entry. Studying Geology does not guarantee any specific occupation, and many of these roles are entered from several different fields. Projected openings are a projection, not jobs promised.
Before you commit to a Geology major
CampusPin does not rank programs. Use these prompts to pressure-test whether a specific Geology program fits your goals, they are decision questions, not claims about any school.
Ask the Geology department
- Which concentrations or specializations are offered, and which faculty lead them?
- What does the typical course sequence look like, and how much is required vs. elective?
- What labs, studios, clinical placements, or research opportunities are available to undergraduates?
- Is there a capstone, thesis, internship, or co-op requirement?
Ask current students & check the curriculum
- How heavy is the workload, and how accessible is the faculty?
- What internships or co-ops did you do, and where do recent graduates end up?
- Does the required curriculum actually match the careers listed above?
- How easy is it to add a minor, double major, or switch tracks later?
