Overview
Geosciences offer exciting opportunities for students with an interest in applying a full range of science and mathematical skills to understand the earth's properties and dynamic processes. This is a highly interdisciplinary program that applies physics, chemistry, biology, and mathematics to understand and manage all aspects of Earth and the environment. Geoscientists work everywhere in the world under almost any condition as they search for earth resources, manage the environment and natural hazards, and supervise technical and business enterprises. For more information about exciting careers in Geosciences consult http://about.agu.org/ and www.agiweb.org/careers.html. The extensive scientific and mathematical skills of geoscientists, along with their broad field experience, allow them to pursue careers in many related fields ranging from material science to technical management to scientific reporting.
The internationally recognized faculty in Geosciences has developed four challenging options, described below, that lead to a B.S. in Geosciences. Coursework emphasizes the acquisition and processing of field data beginning with a special course in field methods taken in the spring of the first year. The geology option requires, and the other options recommend, that the student participate in a six-week field camp. The B.S. in Geosciences provides pre-professional preparation that will allow students to continue their education in post graduate programs in science, law, and business.
Earth systems and processes are enormously complicated and require a full range of intellectual skills to decipher and manage. Geoscientists must possess good quantitative skills and a solid understanding of physics, chemistry, and biology. They must be able to read maps, identify rocks, minerals, and fossils as well as visualize earth structures in three dimensions. They must have strong communication skills, both written and verbal. Learning to use these skills in an integrated way is a challenging and rewarding experience.
Degree Requirements
The graduation requirements in effect at the time of graduation apply. When choosing the degree requirements information, always choose the year of your expected date of graduation. Requirements for graduation are referred to via university publications as "Checksheets". The number of credit hours required for degree completion varies among curricula. Students must satisfactorily complete all requirements and university obligations for degree completion.
The university reserves the right to modify requirements in a degree program. However, the university will not alter degree requirements less than two years from the expected graduation year unless there is a transition plan for students already in the degree program.
Please visit the University Registrar website at http://registrar.vt.edu/graduation-multi-brief/index1.html for degree requirements.
Geology Option
The Geology option offers a detailed coverage of the broad range of classic disciplines within the geosciences. This option emphasizes the study of minerals, rocks and fossils, and teaches the student how to understand the processes and history of the earth based on the occurrences and relationships of these materials at or near the Earth's surface.
Geochemistry Option
The Geochemistry option is designed for those students who have special interest in the chemical aspects of the Earth and its materials.
Geophysics Option
The Geophysics option offers the student the opportunity to specialize in the branch of the geosciences that investigates physical earth processes such as earthquakes and that images the interior of the earth through surface-based physical measurements.
Earth Science Education Option
The Earth Science education option provides students with a broad earth science curriculum that meets the content goals for secondary earth science teaching. Certification for Earth science teaching is not provided in the program. Information about teaching certification in Virginia can be obtained from the Department of Teaching and Learning.
Minor in Geosciences
The requirements to earn a minor in Geosciences can be found on its checksheet by visiting the University Registrar website at http://registrar.vt.edu/graduation-multi-brief/index1.html.
Graduate Program
The department offers M.S. and Ph.D. degrees in geosciences with specializations in many sub-disciplines. (See the Graduate Catalog for further information.)
Satisfactory Progress
University policy requires that students who are making satisfactory progress toward a degree meet minimum criteria toward the General Education (Curriculum for Liberal Education) (see "Academics") and toward the degree.
Satisfactory progress requirements toward the B.S. in Geosciences with any of the available options can be found on the specific major checksheet by visiting the University Registrar website at http://registrar.vt.edu/graduation-multi-brief/index1.html.
