Horn Professor Chatterjee; Pevehouse Professor Asquith; Professors Barnes, Barrick, Güven, Haragan, Leary, and Lehman; Associate Professors Chang, Gurrola, Jurica, and Karlsson; Assistant Professors Doggett, Nagihara, Ridley, and Yoshinobu; Research Assistant Professor Gill; Joint Professors Arnold, Lee, and Rainwater; Adjunct Faculty: Johnson and Stout.

This department supervises the following degree programs: GEOSCIENCE, Bachelor of Arts, Bachelor of Science, Master of Science, Doctor of Philosophy; ATMOSPHERIC SCIENCE, Master of Science. Areas of specialization at the undergraduate level include geology and geophysics and a minor in atmospheric science.

All bachelor's degree programs require an 18-hour minor which may be in a single discipline or selected from a variety of disciplines with departmental approval. The minor for a Bachelor of Science degree program is usually in biology, chemistry, physics, mathematics, computer science, engineering, supporting areas of geosciences, or a combination thereof. Fewer restrictions are placed on the selection of a minor for a Bachelor of Arts degree.

Grades below C in required courses of the major, minor, or adjunct requirements of a geosciences program are not acceptable in fulfillment of the degree requirements.

The program leading to the Bachelor of Arts degree is designed to provide a broad liberal arts background and basic training in the principles of geosciences. The program is designed for the student with strong interests in earth processes and the history of nature's initiation of and response to continuous change. The degree is tailored toward instruction in making one aware of the transient character of both physical and aesthetic resources. Programs leading to the Bachelor of Science degree provide more intensive training in the physical sciences.

Teacher Education. The Department of Geosciences cooperates with the College of Education in offering plans for teacher certification in earth science, and life-earth science at both the elementary and secondary school levels. The student should consult the Department of Geosciences concerning course work required for earth science certification and the College of Education for requirements in professional education.

Students who major in geology (B.A. or B.S. degrees) and wish to teach earth science at the secondary level must complete the following courses in the earth sciences, in addition to other degree requirements and professional education courses: ASTR 1300, 1100; ATMO 1300, 1100; GEOL 1303, 1101, 1304, 1102, 2305, 3301, 3322, 3402, 3421, 3450, and 6 hours from the following: GEOL 3323, 3600, or 4324.

Students who major in another field and wish to qualify to teach earth science at the secondary level must complete (in addition to other degree requirements and professional education courses) ASTR 1300, 1100; ATMO 1300, 1100; GEOL 1303, 1101, 1304, 1102, 2305, 3322, 3421, 3450, and one of the following: GEOL 3301, 3323, or 3402.

Students may also satisfy the requirements for teaching earth science at the secondary level under the Multidisciplinary Science Major, with an emphasis in earth science. This major is administered by the College of Education. In addition to the basic science course work, the earth science emphasis requires GEOL 2305, 3301, 3322, 3421, 3450, and 6 hours from the following: GEOL 3323, 3402, 3600, or 4324.
