geo-, ge- +
(Greek: earth, land, soil; world; Gaia (Greek), Gaea (Latin), "earth goddess")
One geologist claimed that geologists go to rock'n'roll concerts for entertainment and when they relax, they do it in a rocking chair; but their favorite kind of transportation is a rocket.
2. The science which includes the structure and mineral constitution of the globe; structural geology.
3. The study or science of the earth, its history, and its life as recorded in the rocks; includes the study of geologic features of an area; such as, the geometry of rock formations, weathering and erosion, and sedimentation.
2. Having properties, or characteristics, of geomagnetism.
The study of the sources, configurations, and changes in the earth's magnetic field and the study and interpretation of the remaining magnetism in rocks as a result of the earth's magnetic field when the rocks were formed which is known as paleomagnetism.
2. That terrestrial great circle which is 90° from the geomagnetic poles.
The intensity of the magnetic field at the earth's surface is approximately 0.32 gauss at the equator and 0.62 gauss at the north pole.
A gauss equivalent to 1 maxwell per square centimeter and a maxwell is equivalent to the flux that produces one abvolt in a one-turn circuit when the flux is reduced to zero at a uniform rate in one second; while a flux is the electric or magnetic field lines of force that traverse a given cross-sectional area.
2. Unwanted radio frequencies caused by fluctuations in the geomagnetic field of the earth.
2. One of two regions of the earth with very high magnetic field strength, taken to be the points at which a line, drawn between the poles of a magnetic dipole generating the earth's magnetic field and extending out in both directions, would cross the earth's surface.
The north pole of a magnet; such as, a compass needle, is attracted to the geomagnetic north pole because the earth's north pole is actually a magnetic south pole (and its geomagnetic south pole is a magnetic north pole).
The earth's internal magnetic field reverses, on average, about every 300,000 to 1 million years.
This reversal is very sudden on a geologic time scale, apparently taking about 5,000 years.
The time between reversals is highly variable, sometimes less than 40,000 years and at other times as long as 35 million years and no regularities or period times have been discovered so far.
A long interval of one polarity may be followed by a short interval of an opposite polarity.
