[edit intro]

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 [r]: Add brief definition or description (earthquakes and elastic waves)
*   * Gravity [r]: The tendency of objects with mass to accelerate toward each other. [e] (Earth's gravitational field)
*   * Geodesy [r]: Add brief definition or description (size and shape of the earth)
*   * Geomagnetism [r]: Add brief definition or description (including ionosphere, magnetosphere, Van Allen belts)
*   * Geoelectricity [r]: Add brief definition or description and electromagnetic methods (telluric currents, resistivity and conductivity structure, ground penetrating radar (GPR))
*   * Geothermometry [r]: Add brief definition or description (heat from internal processes, radioactivity, heat flow, volcanology, and hot springs)
*   * Hydrology [r]: The interdisciplinary study of the movement, characteristics and distribution of water, surface-water (fresh water and salt water), groundwater, and water-quality. [e] (ground and surface water, sometimes including glaciology)
*   * Physical oceanography [r]: The study of physical processes in the oceans. Topics include currents, tides, large scale ocean circulation and the formation of different water masses, and air-sea interactions such as the generation of surface waves by the wind. [e]
*   * Tectonophysics [r]: Add brief definition or description (geological processes in the earth)
*   * Exploration, engineering, and environmental geophysics [r]: Add brief definition or description
*   * Geophysical Engineering [r]: Add brief definition or description
*   * Glaciology [r]: Add brief definition or description
*   * Mineral Physics [r]: Add brief definition or description
*   * Engineering geology [r]: Add brief definition or description
*   * Geophysical MASINT [r]: Add brief definition or description
