An undergraduate degree in geology is attainable in four full-time years at most colleges and universities. Of the more than 600 schools in the country offering geology courses, at least 386 offer undergraduate or graduate degrees in the Earth science.
In addition to the general education requirements set forth by the university, most require 50 to 60 credit hours in geology courses, as well as additional mathematics, chemistry and physics courses. Some undergraduate programs and all graduate programs require field work. Those earning a degree in geology perform a variety of work including assessing sources of energy and water, exploring mineral and fuel resources, working to resolve environmental problems, restoring natural ecosystems and a number of other functions.
