Physics of the Earth

Physics of the Earth

 

(or geophysics), a complex of sciences that deal with the earth, the internal structure and physical properties of the earth, and physical processes that occur in the earth’s solid shells and in the hydrosphere and atmosphere. Some investigators take the term “physics of the earth” to mean the physics of the solid earth, or lithosphere physics.

Depending on the nature of the physical field studied and on the subject matter of an investigation, the physics of the earth may be classified in the following divisions: terrestrial magnetism, gravimetry, seismology, geothermy, hydrophysics, atmospheric physics, geophysical prospecting, and industrial geophysics. (See alsoEARTH, PHYSICS OF THE SEA, and GEOPHYSICAL PROSPECTING METHODS.)

Although the 'interplanetary billiards' theory of the Moon's origin, which requires a very small initial Earth-Moon distance, neatly fits some of the geochemical facts and is currently very fashionable for that reason among astronomers and lunar scientists, it is wildly improbable on several other counts and is regarded with great scepticism by at least some geophysicists: Williams, indeed, asserts that his evidence is incompatible with the Moon's ever having been much closer than now (although the present writer can see nothing in his paper which justifies that conclusion); and see Frank Stacey & Paul Davis, Physics of the Earth, 4th edn.
