Geologist & Geoscientist — UPSC Combined Geo-Scientist Route

8 min read · Govt posts via UPSC · M.Sc Geology or listed earth sciences

Geologists study rocks, minerals, groundwater and earth processes — finding minerals and oil, assessing landslide and earthquake risk, and managing water. The main government route is the UPSC Combined Geo-Scientist Examination, which recruits geologists, geophysicists, chemists and hydrogeologists for bodies such as the Geological Survey of India (GSI) and the Central Ground Water Board (CGWB).
