Earth Science, Geology and Meteorology

Exploration by Earth Science students


Earth Science Courses

EASCI 161 Earth Science 4 Units
EASCI 162 Introduction to Oceanography 4 Units 

The study of earth science focuses on the physical, chemical, and biological aspects of the natural processes that govern natural resources, natural hazards, weather, and climate of the Earth system. Students should consult with a counselor or visit for more information on university admission and transfer requirements.


Upon satisfactory completion of this award, the student should be prepared to:
1. Identify, describe, and explain the causes and consequences of the various physical processes that transfer energy into, within, and out of the earth system.
2. Identify, describe, and explain the causes and consequences of the various chemical processes that control the transformation of matter within the earth system.
3. Identify, describe, and explain the causes and consequences of the various interactions.

The Associate in Science in Geology for Transfer degree includes lower division coursework that is required for transfer and which focuses on the mastery of
the identification of earth materials and the use of geologic maps, stratigraphic sections, and remote sensing imagery, using these techniques to model real- world
The Associate in Science in Geology for Transfer degree is intended for students who plan to complete a bachelor’s degree in Geology at a California State University
campus. Students completing this degree are guaranteed admission to the CSU System, but not to a particular campus or major. Students transferring to a CSU
campus that does accept this degree will be required to complete no more than 60 units after transfer to earn a bachelor’s degree. This degree may not be the best option
for students intending to transfer to a particular CSU campus or to a university or college that is not part of the CSU system. In all cases, students should consult with a
counselor for more information on university admission and transfer requirements.


Upon satisfactory completion of this award, the student should be prepared to:
1. Identify the rock-forming minerals, ore minerals, igneous rocks, sedimentary rocks, and metamorphic rocks, utilizing the physical and chemical properties of each.
2. Analyze and interpret stratigraphic columns, geologic profiles, and geologic and topographic maps to determine the geological and structural history of a given region.
3. Analyze the geological hazards of a given region based on identification of the tectonic and erosional processes acting on the landscape.
