Cost & earnings at Indiana University Bloomington What students borrow here, and what they go on to earn
The Bachelor's in Geological and Earth Sciences at Indiana University Bloomington provides a foundation in how the solid Earth, surface environments and the atmosphere interact, combining classroom instruction with laboratory work and field training. It suits students who enjoy chemistry, physics and outdoor fieldwork and who want careers in environmental management, natural-resource sectors, research or geoscience-related technology.
This undergraduate programme combines core geological science principles with laboratory techniques, quantitative methods and field experience. Typical topics include mineralogy, petrology, structural geology, sedimentology and stratigraphy, geochemistry, geophysics, paleontology and hydrogeology. Students also study related quantitative and environmental subjects such as calculus, statistics, physics, and chemical fundamentals to support analytical work.
Practical training is a major element: hands-on laboratory courses teach petrographic microscopy, geochemical analysis and sedimentary/rock description, while dedicated field courses develop mapping, sampling and observational skills in a range of landscapes. Many students gain competence in geographic information systems (GIS), remote sensing and data visualisation through elective modules or department-supported lab work.
The programme structure normally includes a set of required core courses, departmental electives, general education requirements and opportunities for independent study. Advanced undergraduates can undertake capstone projects, senior theses or supervised research with faculty in areas such as sedimentary systems, tectonics, environmental geology or climate-related studies.
Applicants are expected to have a solid background in mathematics and the physical sciences. Typical qualifications include completion of high-school level mathematics (including precalculus or calculus), chemistry and physics. Strong performance in these subjects is important for success in core courses.
For transfer applicants, college-level credits in introductory geology, chemistry, physics or calculus will be evaluated for placement. International applicants should present the equivalent national secondary credentials and evidence of preparation in quantitative science. The department values demonstrated interest in fieldwork, laboratory experience or related extracurricular activities, though these are not mandatory.
Graduates with a bachelor’s in Geological and Earth Sciences are well placed for a broad range of careers. Common pathways include environmental consulting, hydrogeology and water-resources management, geotechnical roles for infrastructure projects, natural-resource exploration and mining, and roles in energy and renewable-resource assessment. Skills in GIS, data analysis and field methods are also valued in government agencies, non-governmental environmental organisations, and environmental compliance.
Many alumni continue their training through specialised master’s degrees or PhDs in geology, geophysics, environmental science, engineering geology or climate science, or they move into related professional programmes such as environmental law and policy, depending on their interests.
Studying Earth sciences at Indiana University Bloomington gives access to a supportive liberal-arts environment with opportunities for close faculty mentoring and undergraduate research. The department emphasises experiential learning through laboratory work, field courses that make use of Indiana’s varied glacial and bedrock terrains and regional field trips to broader geologic provinces.
Students benefit from campus resources such as computing and GIS facilities, departmental laboratories and a range of campus-wide research centres and internship connections that help bridge classroom learning with professional experience. The programme’s flexible curriculum allows students to combine geology with complementary disciplines — for example environmental science, geography, or data science — to tailor their degree to specific career goals.
