Geologist
Geologists study the Earth, including its rocks, minerals, soils and water and the processes that shape them.
Also called: Earth sciences · Geoscience · Geological sciences · Applied geology
Updated How we use data
A geology degree studies the Earth: its rocks, minerals, fossils and structure, and the processes that shape it, from volcanoes and earthquakes to groundwater and past climates. Graduates often work as geologists, environmental scientists or engineering geologists in mining, energy, construction, water supply and environmental protection.
Many geology graduates work as geologists in mining, quarrying, oil and gas or geothermal energy, or as engineering geologists on construction and infrastructure projects. Others become environmental scientists or environmental engineers, working on contaminated land, groundwater and waste. Newer areas include carbon storage, minerals for batteries and natural hazard assessment. Some graduates move into civil engineering, usually after further study, or into data analysis and teaching.

Environmental scientists study the natural world and how human activity affects it.
Civil engineers plan, design and oversee the building and upkeep of roads, bridges, railways, tunnels, water systems, dams and large buildings.
Environmental engineers design systems that protect people and nature from pollution, such as drinking water and wastewater treatment, air pollution control, waste and recycling facilities, and the clean-up of contaminated land.
Other roles graduates go into: Hydrogeologist · Engineering geologist · Geophysicist · Geotechnical engineer · Exploration geologist
In the UK and much of Europe, a geology bachelor's degree usually takes three years, and a four-year integrated master's or a separate master's is common for professional roles. In the United States and Canada it is typically a four-year programme, often called geology or earth sciences, and many geologists later take a master's. Fieldwork is central almost everywhere, with field courses and often an independent mapping project. Entry usually requires science and mathematics at school. Some programmes are accredited by national geological bodies, and in Canada and many US states geologists need professional registration or a licence for certain work.

A master's degree is common and often expected for specialist roles in hydrogeology, engineering geology, geophysics and mineral exploration. A PhD leads to research in universities, national geological surveys and industry. Once working, many geologists apply for chartered or licensed professional status through their national geological or geoscience body, which usually needs several years of experience.
Common jobs include geologist, engineering geologist, hydrogeologist, geophysicist, environmental scientist and environmental engineer. Graduates work in mining, energy, construction, water supply, environmental consultancy and national geological surveys. Some move into civil engineering, data analysis, teaching, or natural hazard and risk assessment.
Geology skills are needed for water supply, construction and natural hazards, for finding the minerals used in batteries and renewable energy, and for storing carbon underground. At the same time, jobs in oil, gas and mining rise and fall with prices. Skills in data, GIS and environmental work help you move between sectors.
Geology studies the solid Earth: rocks, minerals, fossils and the processes below the surface, using chemistry and physics. Geography studies the Earth's surface and the relationship between people and places, including landscapes, climate, cities and populations. Physical geography and geology overlap, but geology is usually more technical and laboratory-based.
You need a solid base, but usually not the level required for physics or engineering. Most programmes use mathematics and statistics for geophysics, modelling and data analysis, and some offer support modules. Chemistry and physics at school are also useful, and many programmes ask for at least one science subject.
A geography degree studies places, people and the environment, and how they affect each other.
An environmental science degree studies how the natural world works and how human activity affects air, water, soil, wildlife and climate.
A chemistry degree teaches how substances are built, how they react and how to make and analyse new materials, through theory and a lot of laboratory work.
A physics degree explores the laws that govern the universe, from particles and atoms to materials, energy and stars, using mathematics, experiments and computer models.
