Geologists study the physical processes that create and change the landscape of the Earth as well as rocks and minerals. The U.S. Bureau of Labor Statistics predicts a 22 percent growth in the field of geology through 2016, resulting in the creation of 6,800 new jobs in a variety of geology-related fields.
Petroleum geologists create maps that depict oil and other natural resource deposits across the globe. Oil and gas companies as well as government organizations employ petroleum geologists.
Engineering geologists serve as consultants to mechanical and civil engineers during projects that involve large amounts of excavating or drilling away at rock on the best way to utilize and modify the landscape. Engineering geologists often work for consulting firms but also find employment with construction and engineering firms.
Mineralogists study and identify minerals and precious stones and also create maps of possible mineral deposits. They work for mining companies as well as for appraisers involved in the valuation of jewels.
Paleontologists study ancient rock formations to gain information about changes in climate as well as animal and plant life. Paleontologists typically conduct research for universities and private institutions and are also employed by museums.
Volcanologists study the activity of volcanoes and assist in predicting the likelihood of future eruptions. They typically work as consultants for emergency planners.
