To become a geologist you typically need a bachelor's degree in geoscience or a related field, such as physical science or natural resources, with plenty of fieldwork and lab experience. Some employers prefer a master's or doctorate, and most states require a licence if you offer geology services to the public, which usually means meeting education and experience rules and passing an exam.
Geologists study the physical side of the Earth: rocks, soil, water and the forces that shape them. The work takes you from remote field sites to labs and offices, and it feeds everything from oil and gas exploration to environmental protection.
BLS groups geologists under geoscientists, so the US figures below come from the Bureau of Labor Statistics (BLS) Occupational Outlook Handbook geoscientists profile. The UK route comes from the National Careers Service geoscientist profile. I read both as of October 2026.
Geologist pay and jobs at a glance
| Measure | BLS figure (geoscientists) |
|---|---|
| Typical entry education | Bachelor's degree |
| Median pay (May 2025) | $101,920 a year |
| Lowest 10% earned less than | $59,330 |
| Highest 10% earned more than | $200,230 |
| Jobs in 2025 | 25,400 |
| Projected growth, 2025 to 2035 | 5%, faster than average |
| Openings each year | About 1,800 |
Those are May 2025 medians, as published as of October 2026. The top end is notable: the highest 10% earned more than $200,230.
How to become a geologist, step by step
- Study science and math at school. Geoscience degrees include mineralogy and geology alongside mathematics and engineering.
- Pick a geoscience degree. Some programs focus on one area, such as environmental geology, while others train you as a generalist.
- Take every chance at fieldwork. BLS says programs usually involve geology fieldwork, and lab experience is important for anyone entering the field.
- Do an internship. Interns usually work under a senior geoscientist, preparing for field visits, collecting samples and writing reports.
- Consider a graduate degree. A master's or doctorate involves more specialization and research, and may make you more competitive for some entry-level jobs.
- Get licensed if you'll work for the public. BLS says most states require it for geologists who offer services to the public, such as work on civil engineering projects, environmental protection and regulatory compliance.
The licence most people don't know about
Plenty of geology careers start without a licence. But if your work touches public projects, most states expect you to hold one. Requirements vary by state, and BLS says you'll typically need to meet minimum education and experience rules and pass an exam. Your state's licensing board sets the details, and CareerOneStop lists the boards.
Types of geoscientist
Some geoscientists stay generalists and others specialize. BLS gives examples that show how wide the field is:
- Environmental geologists study how pollution and waste affect air, soil and water.
- Petroleum geologists test rock and sediment samples for oil and gas.
- Paleontologists study fossils to trace the history of plant and animal life.
- Hydrologists study water and how it moves through the Earth's crust.
- Seismologists study earthquakes and related events such as tsunamis.
- Oceanographers study ocean waters and their effect on coasts and climate.

Field, lab and office
BLS says geoscientists usually split their time between the field, the lab and the office. Fieldwork can mean long stretches outdoors or travel to remote locations. Oceanographers may spend months at sea on a research ship, and paleontologists may spend long periods on expeditions.
Most geoscientists work full time, and some work more than 40 hours a week. Schedules can include irregular hours during fieldwork, and you'll often travel to meet clients. If you want a job where no two weeks look the same, that's a plus. If you need a fixed routine at home, it's worth thinking about before you commit.
Where geologists earn the most
Industry makes a big difference. BLS reported these medians for May 2025:
| Industry | Median pay (May 2025) |
|---|---|
| Mining, quarrying, and oil and gas extraction | $158,590 |
| Federal government | $119,430 |
| Management, scientific and technical consulting services | $93,600 |
| State government | $90,820 |
| Architectural, engineering and related services | $83,190 |
The biggest employer, architectural and engineering services with 27% of jobs, pays the least of these five. Mining and oil and gas pays the most, and that's also where the long trips to remote sites tend to be.
Skills that help
BLS lists communication, critical thinking, problem solving, outdoor skills and physical stamina. The last two are what set this job apart. You may hike to remote places carrying equipment, spend long periods outside and camp overnight on fieldwork, and BLS notes that travel is frequent.

The UK route
The National Careers Service says a professional geoscientist needs a degree in a relevant subject, and it's becoming more common for new entrants to hold or work towards an MSc or PhD. You'll usually need 2 or 3 A levels, including a science, for a degree.
There's also a Geoscientist Level 6 Degree Apprenticeship, and a Geotechnical Engineer Level 7 Integrated Degree Apprenticeship if you already have a first degree. The Geological Society has more on careers.

My verdict
Geology pays well, with a BLS median of $101,920, and it suits people who'd rather be outdoors than at a desk all week. Get a geoscience degree with real fieldwork, add an internship, and check your state's licensing rules early if you want to work on public projects. The best pay is in mining and oil and gas, so think about how much remote travel you're happy with.
