geophysics
1. The physics of the earth and its environment, including the physics of fields; such as, meteorology, oceanography, and seismology.
2. The study of the earth by quantitative physical methods; especially, by seismic reflection and refraction, gravity, magnetic, electrical, electromagnetic, and radioactivity methods.
3. The scientific study of the physical characteristics and properties of the solid earth, its air and waters, and its relationship to space phenomena.
4. The science that deals with the weather, winds, tides, earthquakes, etc.; and their effects on the earth.
5. The soils, sediments, and rock layers of the earth's crust, both continental and beneath the ocean floors.

The meaning of the word geophysics is undergoing changes. The classical methods of geophysics are being applied to the planets now that we can reach them.

Seismological techniques are being used to study the interior of the moon, and magnetic field measurements are important probes for the planets.

The name will not change; however, because it is a most encompassing science, ranging from petroleum exploration on the earth to the understanding of the most distant planets.
