Geology is the Science which studies the earth’s history, composition and structure. The term geosciences is used to cover all geological disciplines as each of the geological scientists involve themselves in multidisciplinary work. It includes geochemistry, geophysics, sedimentation, economic geology, and engineering geology as well as historical geology which relates to the study of history of the earth’s crust by studying the formation of rocks, geophysicists use the principles of physics and mathematics to study the earth’s internal composition, surface and atmosphere and also magnetic, electrical and gravitational forces. Geochemistry is the study of chemical composition of the Earth. 

Working Conditions
A geologist’s work can be laboratory based or field based. Most geologists work or supervise exploration work at a variety of sites- deserts, land forms, ocean floors, riverbeds, mountains, etc. Field jobs involve travelling and working outdoors often in difficult situations.

Geologist’s need scientific acumen along with the power of observation, analysis, logic and a spirit of investigation. Good numerical aptitude, clarity and precision in dealing with data of various types is needed.
