Geophysics: Difference between revisions

Revision as of 18:13, 18 March 2007

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
