Geophysics
Encyclopedia : G : GE : GEO : Geophysics
Geophysics, the study of the earth by quantitative physical methods, especially by seismic reflection and refraction, geodesy, gravity, magnetic, electrical, electromagnetic, and radioactivity methods.
It includes the branches of:
- Seismology (earthquakes and elastic waves)
- Gravity and geodesy (the earth's gravitational field and the size and form of the earth)
- Atmospheric science, which includes:
- * Atmospheric electricity and terrestrial magnetism (including ionosphere, Van Allen belts, telluric currents, Radiant energy, etc.)
- * Meteorology and Climatology, which both involve studies of the weather.
- * Aeronomy, the study of the physical structure and chemistry of the atmosphere.
