地球科学关注的是地球的整个物理结构以及过去四年半的十年中发生在地球内部及其之上的物理和生物事件的历史。地球科学家对整个地球（从古代到现在以及未来）都感到好奇，他们使用化学，物理学，生物学，数学和其他科学工具研究地球。在俄亥俄州立大学，学生可以从四个专业中获得理学学士学位：地质科学专业专注于地质学的传统领域，包括矿物学和岩石学，沉积和地层学，古生物学和地球化学。追求该专业的学生将为在各种行业中的就业以及地质科学研究生做好充分的准备。地球系统科学的专业领域侧重于传统地质科学以外的领域，包括水文地质，冰川学，海
Earth sciences concern the Earth's entire physical makeup and the history of the physical and biological events that occurred within and upon it over the past four and a half billion years. Earth scientists are curious about the whole Earth, from its ancient past to its present and future, and they use the tools of chemistry, physics, biology, mathematics and other sciences to study Earth. At Ohio State, students choose from four specializations for the bachelor of science degree: The geological sciences specialization focuses on the traditional areas of geology, including mineralogy and petrology, sedimentation and stratigraphy, paleontology, and geochemistry. Students pursuing this specialization will be well-prepared for employment in a variety of industries and for graduate school in geological sciences. The Earth system science specialization focuses on areas beyond traditional geological sciences, including hydrogeology, glaciology, oceanography and geomorphology. Students pursuing this specialization explore relationships between Earth sciences and other disciplines, including geography, atmospheric sciences, the biological sciences, economics, natural resources and engineering. The geophysics specialization focuses on quantitative aspects of geophysics and geodynamics and provides students preparation for admission to competitive graduate programs in geophysics, and for geophysics positions within the energy industry. The petroleum geology and geophysics specialization combines aspects of the geological sciences and geophysics programs and trains students interested in graduate study in petroleum geology and geophysics, internships at major oil companies, and for immediate employment at small- and mid-sized petroleum companies.
