Earth and Space Sciences seeks to further our understanding of the Earth, the solar system, and their histories. The scope extends from the center of Earth to the rim of the solar system, and activities cut across traditional disciplines of physics, chemistry, biology, geology, and mathematics. The discipline examines Earth's interior structure, chemistry, motion, and dynamics; the processes affecting its landscapes, including ice and climate; natural hazards; the surrounding space environment; planetary processes; and geobiology.
The Bachelor of Science in Earth and Space Sciences is designed for students interested in geology and geophysics, and a career path in graduate studies or in the private sector where field and technology experiences and problem-solving skills are an important asset. Students pursuing the B.S. in Earth and Space Sciences choose from one of four options: Geology, Biology, Physics, or Environmental Earth Sciences. The Bachelor of Arts in Earth and Space Sciences enables students to obtain a broad understanding of earth sciences as a background for professional careers such as science journalism, environmental law, science education, and environmental policy.
This program of study leads to the following credentials:
