What a is geologist?

Answer 1

In Greek/Latin, "geo" means "earth". "-ology" means "the study of". From this, it is easily deduced that "geology" means "the study of the earth" and that a "geologist" is one who studies the earth. A more specific definition states that a geologist is someone who is a contributor to the science of geology. They study the processes and physical structure of the Earth and also the planets of the solar system. Click on the link below.
A geologist is someone who is actively involved in the field of Geology, so it would be good to also know what Geology is.

Geology is the study of the Earth (not rocks). Therefore, a geologist is someone who studies the processes of the Earth, including deep inside, and we can also look into the depths of space to see where the Earth fits into a larger picture. It's certainly a much larger study field than most people think...rocks? I think not.

Of course, a geologist does study rocks, but most people have no idea why. 'What is the point of a geologist?' could be a follow up question, so I will answer this also. A geologist is hired for two reasons as far as I know:

1. To investigate the geological history and structure of an area (i.e. to carry out a geological survey)
2. To advise a solution to a geology-related issue

The work done is very important, and fundamental to many jobs. Locating where a building should be constructed is more difficult than most people realise. Some spots are unstable, and in earthquake-prone areas, any structures would collapse easily. That's an example of a job a geologist might be involved in.
