Geologists are earth scientists who study the earth, its processes, properties, structure and composition.

Geologists examine rocks, minerals, and fossil remains to identify and determine the sequence of processes affecting the development of the earth.

Geologists also apply their broad knowledge of chemistry, physics, biology, and mathematics to explain these phenomena and to help locate mineral and petroleum deposits and underground water resources.

Geologists serve the scientific and broader community by preparing geologic reports and maps, and interpret research data to recommend further action for exploration and study.
