Geological science is the study of Earth and other planets with an emphasis on the processes that have shaped them since the origin of the solar system. Students explore topics such as the co-evolution of life, oceans, atmosphere and the Earth's climate system, and the record of that evolution encoded in rocks, soil, ice and isotopes.

The BS program in earth and space exploration with a concentration in geological sciences educates students in the fundamentals of geological sciences, providing a solid background in chemistry, mathematics and physics as well as mineralogy, structural geology, field geology and a variety of geologic subdisciplines.

Students gain a strong understanding of field methods as well as modern computing, remote sensing and instrumentation to effectively study the natural environment and Earth's resources. Graduates of the program can apply their knowledge for the benefit of Arizona, the nation and society in general.

Students currently enrolled in the Bachelor of Science in earth and space exploration (geological sciences) may not pursue a concurrent degree with the BS in earth and space exploration, the BS in earth and space exploration (astrophysics), the BA in earth and environmental studies, the BS in earth and space exploration (astrobiology and biogesciences) or the BS in earth and space exploration (exploration systems design) due to the high level of overlap in curriculum. Students should speak with their academic advisor for any further questions.
