Geosciences is the study of the Earth, including its formation and chemical, physical and biological aspects. These studies form the basis for improved approaches to issues in natural resources, geohazards, and environmental impacts. Geoscientists also study how the lithosphere interacts with the hydrosphere and atmosphere. The department's renowned Laboratory of Tree-Ring Research uses tree-rings to study climatic, ecological, environmental and archaeological problems. Majors study tectonics, geophysics, geochemistry, geochronology and thermodynamics, seismology, paleobiology, economic geology and quaternary studies, which examines the more recent history of the Earth. Students may concentrate on geology or geophysics. A teaching major is also offered, leading to certification to teach earth sciences in Arizona public schools.

Admissions Requirements:

No Additional Requirements

Math Required:


    This strand involves skill and facility with calculus. The S-strand begins at one of two calculus options - MATH 124 (Calculus I with Applications) or MATH 125 (Calculus I). Students who successfully complete the S-strand may continue on to MATH 129 (Calculus II), MATH 223 (Vector Calculus), or beyond. Those who choose but are not ready to begin the S-strand will be required to take preparatory work.
Second Language Required:

2 Semesters

  • Scoring the equivalent of second-semester skill level on an entrance or placement examination administered by The University of Arizona.
  • Completion with a C or better of a second semester course at the post-secondary level.
  • An AP (Advanced Placement), IB (International Baccalaureate) or CLEP (College Level Entrance Program) language score determined by the individual language department.
  • In the College of Engineering by a method determined within the College; however, all students in the college must also take a language placement examination on entrance to the University.
