Subfields of physics

Geophysics () is a physical science concerned with the processes and properties of Earth and its surrounding space environment, studied using quantitative and observational methods. It focuses primarily on Earth’s shape and its gravitational, magnetic, and electromagnetic fields. It also studies internal structure, composition, and dynamics, and their surface expression in tectonics, volcanism, and rock formation. Geophysics also encompasses a broader Earth-system and planetary perspective, including the oceans, atmosphere, cryosphere, ionosphere, magnetosphere, as well as solar–terrestrial in
