Are these different names for the same thing or different/wider/narrower subjects than one another? And, if different, would they all be as useful/highly regarded for future study or careers?
I am trying to get some ideas for talking through options with my nephew. He is interested in doing a degree in geology or similar, doesn't want to work in the oil industry (which seems to be a big employer of geologists), but interested in maybe going on to PG study and working in an environmental area like floods or erosion.
And if any geologists/earth scientists have any ideas for relevant work experience, volunteering, reading, etc, that would be much appreciated too.
