The department's geology courses offer the student a general knowledge of the earth, its structure, composition, internal and external processes, and past history. Emphasis is placed upon field and laboratory investigation directed towards development of useful skills and a grasp of basic theoretical and working concepts. Building on this framework, the student can pursue any one of several avenues of study leading to majors in geology and earth science teaching; or to a minor in geology.
The Geology major has three options available leading to either a Bachelor of Science degree or a Bachelor of Arts degree. Both degrees require a core of geology courses plus supporting courses in other science disciplines and mathematics.
