Hello Vemula,
Geologists supervise exploration work in deserts, ocean floors, riverbeds, mountains, etc.They research and carry out a scientific study with organizations involved in geological work who locate physical data and material for study from near Earth's surface and in the sea. Analyse information collected through seismic prospecting; examine surface rocks and samples of buried rocks, study information collected by satellites. Identify rocks, minerals, and fossilsConduct geological surveys, construct maps, measure Earth's gravity and magnetic field. Research for locating oil, natural gas, and minerals. Work in laboratories to study samples from the earth or seabed. Study the flow of oil and water through rocks. In government departments, they monitor waste disposal sites and water supplies.
Geological Survey of India and the Central Ground Water Board select geologists through an examination conducted by the Union Public Service Commission (UPSC).
