Job opportunities in geology and geophysics are generally good, especially if you are willing to travel and relocate in response to the market. Geology jobs (and geology graduate degrees) fall into two broad categories: "Soft rock", i.e. pertaining to sedimentary deposits, where the jobs tend to be in petroleum, coal, uranium, etc. and "hard rock" where the jobs tend to be in extraction of precious metals. Hydrology and environmental (cleanup) geology are also good fields. Seismology (earthquakes), volcanology, planetary geology, and paleontology are fascinating areas also, but jobs in these areas may be harder to come by as they tend to be more research-oriented.
One thing to be aware of is that geology jobs tend to be cyclic depending on the market. When oil or metals prices are high, geologists are in high demand; sudden price drops can leave recent hires vulnerable.
As Lemaitre1 implied, a geophysics probably makes you more marketable than just geology. As a retired geologist, I can tell you that both are fascinating and if you enjoy them, go for it. You'll meet great people, travel to interesting places and more than likely be employed if you are willing to be flexible in the early years of your career.
