Career in Geology – A good career option after 12th

Once you have passed your class 12th the next step is to choose a course which will take you to the career path which you have thought of yourself. Well most of us still look at Engineering and Medicine as career. But there are many good career options beyond these two. Today I will talk about one such career option and that is Career in Geology or Career as Geologist. It also called as career in Earth Sciences.

Who is a Geologist?

A geologist is a person who does a scientific study of earth. By Scientific study we mean to study everything that constitutes the earth and can be solid, liquid or even gaseous matters. Also a geologist also may study other terrestrial planets.

So in a nutshell a geologist will study everything related to earth. It’s mineral composition, earth quakes, volcanic eruptions, tectonic plates, water resources, ores and mining etc. So if you love nature and if you like to study earth, this is the field you should be in.

Sounds Interesting? lets look at what is needed to become a Geologist.

How to become a Geologist – Career option after 12th

The first step to become a geologist is to gain knowledge in this area, that is get trained in this area by going through a formal education in this field. There are graduate level courses, post graduate courses and even a doctorate degree.

If you have a doctorate degree, you become a earth scientist or also called as geo scientist or environmental scientist.

Minimum requirement to study Geology

If you have decided to get a degree in this field, you need to get at-least a graduate degree in this field.

  • You should have passed 12th with any stream (ie. 12 years of formal education)
  • Apply for a graduate degree in Geology ( minimum 3 year graduate degree or you can also opt for a BE/BTECH in mining)
  • Then if you want to apply for a masters degree, you may need to write GATE exam to get into a good college. Many universities also have their own entrance test
  • You can also opt for further study abroad, they have some good study options
  • And if you want to study further, then you can opt for PHD in geology
