most U's that offer a BS in geophys , have the majors be heavily involved in general physics than geo.
Many of the subjects in things like petrology, structure, tectonics etc are not thoroughly covered and are done without the kids ever seeing the field. I taught undergrad and grad applied geo ( economic), and I reccommend a good background in geo, geochem econ and you can be entrepreneurially employed or be involved in the teaching field. Usually the terminal degree is a "Master of Applied Science" which is a dual major in most U's.
Much geophys has BS degree holders working as "juggies" or data manipulators.
Are you more interested in academics or getting "dirty in the field" .
