The Geosciences are concerned with the Earth, its origin, composition and evolution through time, as well as studying the processes that affect the Earth and the life forms that have lived on it in the past. Many geoscience applications use computer technology, including Geographic Information Systems, Remove Sensing, numerical models of groundwater flow and contamination and surface water flow models for mapping the Earth and modeling the processes that affect the planet.

Geoscientists are employed in environmental, engineering and resource management services, Geographic Information Systems/mapping and remote sensing applications.  About 20 percent work for oil and gas extraction companies or metal mining companies.  One geoscientist in seven is self-employed; most are consultants to industry and government.  More than 9,000 geoscientist work for governmental agencies such as the Utah Geological Survey and Department of Environmental Quality or the U.S. Geological Survey.  There are many employment opportunities for Earth science teachers in public and private schools.
