Chair, Professor Stephen O. Moshier
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.
The Bachelor of Science option requires 36 credits in geology including GEOL 211 or 221 (or 201), 321, 336, 342 or (or equivalent), 343, 344, 443, a summer field experience (412 or equivalent), and the 494 capstone seminar, plus four elective hours in geology. Required supporting courses are CHEM 221 (or ), PHYS 231 (or ) and either CHEM 222 (or ) or PHYS 232 (or ), plus MATH 221 or ( and also recommended).
The Bachelor of Arts option requires 32 credits including GEOL 211 or 221 (or 201), 321, 336, 342 (or equivalent), 343, 344, 443, a summer field experience (412 [six hours] or equivalent), and the 494 capstone seminar. Required supporting courses are CHEM 221 (or or equivalent) OR PHYS 221, AND one quantitative methods course ( /GEOL 241, B EC 321, or equivalent).
The Secondary Teacher Licensure option leads to a double major in Secondary Education and Geology. Requirements are as follows: Bachelor of Arts in Geology coursework, supporting courses in CHEM 236, PHYS 221, or 302, BIOL 201, SCI 321 and education courses as required by the Education Department. A Master of Arts in Teaching (MAT) program is available with the Geology major. A combined Bachelor's/MAT program may be completed in five years and one summer. See the Education section in this catalog.
