   geology, oceanography, meteorology, and astronomy all fall under the category of earth sciences. Physics is a completely separate science from earth sciences being a science of forces and energy. However, it can explain some of the phenomena that occur in earth sciences.

   Once you get into these sciences, you will find a lot of cross-disciplinary stuff like geophysics and geochemistry. While I was going to college, the physics department was combined with geology. Today, it is combined with astronomy instead. There is a lot of incest among the sciences.

   Astronomy is one science that is particularly closely tied to physics. The two sciences get tied together at the both extremes of the physical and temporal scales: very large objects and very small ones; very long time periods and very short ones. Gravitational theory, relativity, subatomic particles and states of matter not available on earth, the Big Bang, the size and configuration of the universe, and the formation of stars and galaxies are subjects fit for both disciplines.

   Physics and chemistry also get tied in with geology and its different subbranches like oceanography and meteorology because geology looks to physics to model the ocean currents, air currents, movements of the earth’s crust, mantle, and core, generation of the earth’s magnetic field, and so on. Geology gets a lot from chemistry as well to determine just what the earth is made of.
