Re: I want to become a geologist
I want to become a geologist but I was wondering is there anything else I can major in besides geology or earth science or geosciences. Do I have to go down that path or can I choose any other major then go to graduate school and finish geology there. If so how does that work?
Systems vary internationally. In the UK where I studies it is common to undertake a single subject (as opposed to "majoring" in a subject) - so for example I studied undergraduate Physics, which meant I did ~25 hours of physics/maths lectures and lab sessions a week.
I then progressed to an MSc in Applied Geophysics, and as part of this we "non geologists" were required to take some of the undergraduate papers from the first and second year geology course.
I'd suggest that majoring in (for example) physics, chemistry or biology wouldn't be a barrier to taking a geo-specialisation at masters level. I would however suggest that you aim to take a few undergraduate papers in geology to provide a basic understanding, and tend towards courses that will be useful in your specialisation (for example, waves and optics for geophysics and so on)
I work now with around 40 different earth science schools internationally; those that successfully attract undergraduates with non-earth science majors into their graduate programmes tend to be the ones that area successful, expanding and growing. Where there is not an influx of new ideas from other science areas tends to be where the departments are in decline.
