Geology Schools and Programs in The United States

Geology Studies in The United States

Geology is the study of the Earth: what it is made of, how it is structured and how processes such as erosion and volcanic activity shape it over time. In the United States the subject is usually taught in a department of geology, geosciences or Earth and planetary sciences. Programmes combine courses in mineralogy and geology with mathematics, physics and chemistry, and almost all of them include fieldwork, according to the Bureau of Labor Statistics (BLS).

How the degree is organised

There is no national list of degree titles in the US: each accredited college or university designs its own programmes. The usual levels for geology are:

• Associate degree (two years) at a community college, often as the first half of a bachelor's degree
• Bachelor's degree (four years), a Bachelor of Science (B.S.) or Bachelor of Arts (B.A.) in geology or geosciences
• Master's degree (typically two years), with more specialisation and research
• PhD (five to eight years), a research degree for a career in research or university teaching

US credits reflect the hours a class meets each week; they are not ECTS credits. The academic year usually runs from August to May, and students normally declare their major at the end of the second year. The Jackson School of Geosciences at The University of Texas at Austin, for example, has eight undergraduate degree options, including a B.S. in General Geology, a B.S. in Hydrology and Water Resources and a B.A. in Geological Sciences. At the California Institute of Technology (Caltech), the Geological and Planetary Sciences major lets students choose a track in geology, geobiology, geochemistry, geophysics or planetary science, after core courses in mathematics, physics, chemistry and biology.

Fieldwork is a central part of the degree. At the Jackson School, the capstone field geology course takes students to field sites across the country in two three-week sections.

Admission, English and visa

For a bachelor's degree you need to have finished secondary school and generally be at least 17. Each university reviews foreign records itself, sometimes through a credential evaluation agency. US universities require an English language proficiency test before admission.

Before applying for a student visa you must be accepted by an institution certified by the Student and Exchange Visitor Program (SEVP), which then issues the Form I-20 (or DS-2019 for exchange programmes). Degree students normally use the F visa. Check the school's accreditation too: according to EducationUSA, recognition of credits and degrees by other institutions and by employers is linked to it.

Costs and funding

Tuition is set by each institution. State universities are generally larger and less expensive than private ones, and community colleges offer lower costs and close ties to state universities. Graduate study in geology is often funded through teaching or research assistantships. At the Jackson School, the most recent starting salary for teaching and research assistants and fellowship stipends was $3,080 a month, with support guaranteed for four semesters in the M.S. programme and ten in the PhD programme (not for the M.A.).

Where to study geology in the United States

Geology is taught across the country rather than in a few centres; no city has more than two schools on this page. Los Angeles, Philadelphia, Denver, Tuscaloosa and Union (New Jersey) each have two. Examples include large public universities such as The Ohio State University, the University of Florida, Purdue University and the University of Washington; private research universities such as Stanford University, Yale University and the University of Southern California; specialised institutions such as the Colorado School of Mines and the South Dakota School of Mines & Technology; liberal arts colleges such as Lawrence University and Colorado College, and community colleges such as Tacoma Community College. Location matters in this subject, because the local landscape is part of the teaching: the Jackson School, for example, describes Texas as a natural laboratory for its undergraduates.

Careers

Graduates work as geologists, environmental geologists, oceanographers, seismologists or petroleum geologists. According to the BLS, geoscientists held about 25,400 jobs in 2025; the largest employers were architectural and engineering services, mining and oil and gas extraction, and consulting services. A bachelor's degree is the typical entry-level education, but some employers prefer a master's degree or PhD. Most states require a licence for geologists who offer services to the public, which usually means meeting education and experience requirements and passing an exam. The BLS gives a median annual wage of $101,920 in May 2025 and projects employment to grow 5 percent from 2025 to 2035, with about 1,800 openings a year.

Frequently asked questions

How long does it take to study geology in the United States?

A bachelor's degree takes four years, a master's degree typically two and a PhD five to eight years.

Is fieldwork compulsory in a US geology degree?

In most programmes, yes. Geology degrees usually include field courses, such as the summer field geology course at The University of Texas at Austin.

Can international students get funding for a master's or PhD in geology?

Often, through teaching or research assistantships. At the Jackson School of Geosciences, for example, admitted M.S. and PhD students with support receive a monthly stipend for a guaranteed number of semesters.

Do I need a licence to work as a geologist in the US?

Most states require a licence for geologists who offer services to the public. Requirements vary by state but usually include education, experience and an exam.
