Geology is the study of the Earth. It is generally divided into two branches: physical geology and historical geology. Physical geology focuses on the solid materials that make up the Earth, and the processes that affect those materials. Historical geology focuses on the history of the Earth, including fossils and the history of life.
Physical geology includes the study of volcanoes, earthquakes, the interior of the Earth, hydrology, mineral resources, and fossil fuels. Historical geology includes the investigation of the history of the Earth, from it’s formation through recent times.
Careers in geology may include searching for oil in the petroleum industry, consulting for environmental firms working in water resources, or site research and mitigation in the construction industry. Research positions are often available with the US Geological Survey, NASA’s Planetary Science and Earth Science divisions, and the Department of Energy.
It is always recommended that you talk to an academic advisor about your educational goals and to learn more about specific programs.
