Geology is the science that studies the origin, history, composition, and structure of the Earth. The word is derived from two Greek roots: geo, meaning of the Earth; and logia, meaning study or science. Geologists work in every corner of the Earth, from ice-covered mountains to the depths of the oceans.

At Bellevue College, Geology is one of five sciences that comprise our Earth and Space Sciences Program (the others are Astronomy, Environmental Science, Oceanography, and Meteorology).
