BA in Earth Sciences in Columbus United States | Ohio State University

Earth sciences explore the complete physical composition of our planet and the timeline of physical and biological developments that have shaped it over 4.5 billion years. Researchers in this field investigate Earth's entire existence—from its distant origins to its current state and future trajectory—employing methods from chemistry, physics, biology, mathematics, and other scientific disciplines. At Ohio State, undergraduates can select among four concentrations for their bachelor of science degree: The geological sciences track emphasizes core geology subjects like mineralogy, petrology, sedimentation, stratigraphy, paleontology, and geochemistry. This path equips graduates for diverse industry roles or advanced studies in geological sciences. The Earth system science concentration extends beyond conventional geology to incorporate hydrology, glaciology, oceanography, and geomorphology, encouraging interdisciplinary connections with geography, atmospheric sciences, biology, economics, natural resources, and engineering. The geophysics specialization emphasizes quantitative geophysics and geodynamics, preparing students for top-tier graduate programs or careers in the energy sector. The petroleum geology and geophysics option merges elements from both geological sciences and geophysics, designed for those aiming for graduate work in petroleum studies, internships with major oil firms, or direct employment with small-to-midsize petroleum companies.
