Geology (Geo means earth and logos means Science). Geology is the branch of science that deals with the study of the earth, its environment, history, minerals etc. Different branches of Geology are structural geology, mineralogy, planetology, geomorphology, geological engineering etc. A person who studies the composition of the earth is known as the geologist. Geologists are scientists who study the earth's crust to obtain an accurate picture of its structure, history, and composition. Geologists play a vital role in exploring the mineral wealth and natural resources. Now a day, career in Geology is gaining lot more popularity. Main function of the geologists is to assess the natural disasters and its effects on environment, to explore areas rich in under-water resources, oil, natural gas and minerals. They can assess whether the conditions in particular areas are suitable for laying railway lines, construction of roads, bridges, buildings etc. The geologists can also explore the natural resources deep in the sea. Their services are also important for oil explorations.They determine the quality of soil by conducting geo-chemical and geo-physical tests. Construction of reservoirs, roads, bridges, underground tunnels etc. is based on the report of the geologist about the density of the earth. Geologists work for private industries, the federal government, museums, colleges and universities. The need for geologists will increase about as fast as the average through the year 2012. Most jobs will result from the growing number of environmental laws and regulations. There will also be a need to replace geologists who retire. Eligibility There are a number of universities and Institutes offering bachelor, master and doctorate degree in Geology. For admission to B.Sc General or honour's, 10+2 with Science either in non-medical or medical subjects with at least 50% marks is required. For master degree, a bachelor degree with Geology as one of the subject is r equired with minimum 50% marks and for Ph.D. there is requirement of at least 55% marks in master degree. However, the rules for admission to bachelor, masters and research degree vary from university to university/institutes. To start a career in Geology, one should complete at least a masters in Geology such as M.A. or M. Sc. in Geology. While a bachelor’s degree in Geology will secure some entry-level positions, the better qualified you are, the better position you can secure. Students interested in a professional career in the Geosciences should prepare to continue their education into advanced degrees. A master’s degree is required for major professional entry-level positions, a Ph.D. is necessary for university teaching and to secure higher-level research positions. Some of the universities in India offering Geology courses are Aligarh Muslim University, Andhra University, Annamalai University, Amravati University, Banaras Hindu University etc. The Union Public Service Commission holds tests for employment of Geologists in Central Government Agencies. They can get good jobs in the Central Ground Water Board and the Geological Survey of India, Coal India, Oil & Natural Gas Corporation, Mineral Exploration Authority, Hindustan Zinc and many other organizations which offer excellent job opportunities for the Geologists. The Defence and Para-military forces also utilize the services of Geologists.
