What is studied by a geologist?
It is the study of the Earth, including Earth’s surface and interior. Geologist study the origin, history, and structure of Earth and the processes that shape it over time. A geologist is a contributor to the science of geology. Geologists study the physical structure and processes of the Earth. Their undergraduate training typically includes significant coursework in chemistry, physics, mathematics and possibly biology, in addition to classes offered through the geology department; volcanology, hydrology, and rock and mineral formation are among the many areas of study. Most geologists also need skills in GIS and other mapping techniques. Geologist survey the rock and mineral structure of an area which can assist in finding water supplies, oil, gas, mineral resources, faults, etc., information that can be useful to mining companies, government agencies, construction companies and so on.
