Geophysics is the study of the earth by quantitative physical methods, namely seismic, magnetic, electrical, electromagnetic, thermal and radioactivity methods.
It includes the branches of:
- Seismology (earthquakes and elastic waves)
- Gravity (Earth's gravitational field)
- Geodesy (size and shape of the earth)
- Geomagnetism (including ionosphere, magnetosphere, Van Allen belts)
- Geoelectricity and electromagnetic methods (telluric currents, resistivity and conductivity structure, ground penetrating radar (GPR))
- Geothermometry (heat from internal processes, radioactivity, heat flow, volcanology, and hot springs)
- Hydrology (ground and surface water, sometimes including glaciology)
- Physical oceanography
- Tectonophysics (geological processes in the earth)
- Exploration, engineering, and environmental geophysics
- Geophysical Engineering
- Glaciology
- Mineral Physics
- Engineering geology
