The Earth Sciences Department includes Geography, Geology, Earth Science, and Environmental Science. Our courses fulfill requirements for General Education (GE) transfer, ADTs (Associate Degree for Transfer) in Geography, Geology, and Liberal Studies, improved employment opportunities, and personal edification.
