Geology is the science that studies the origin, history, composition, and structure of the Earth. Geologists work in every corner of the Earth, from ice-covered mountains to the depths of the oceans. Geologists study more than just rocks – they also study the interactions between Earth’s climate, oceans and life. The research conducted by geologists helps us understand the hazards humans face from Earth processes such as volcanoes and tsunami.

Geology as a major offers strong career opportunities, particularly in areas of disaster management, mining and petroleum geology and environmental geology.

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).
