geo-, ge- +

A method of geologic exploration that utilizes physical and mathematical sciences in measuring and identifying the composition and characteristics of a designated area of the earth's crust.

A geologist who uses physical principles to study the properties of the earth.

The branch of geology in which the principles and practices of physics are used to study the earth and its environment; such as, earth, air, and (by extension) space.

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.

1. A plant that buds in the earth; especially, one with buds living underground throughout the winter.
2. A perennial land, or terrestrial, plant that propagates from organs; such as, bulbs, tubers, or rhizomes that are below ground.
3. A perennial plant; such as, a crocus or tulip, propagated by buds on underground bulbs, tubers, or corms.

Corms are short swollen underground stem bases in some plants; such as, crocuses and gladioli that store food over the winter and produce new foliage in the spring. New corms often form on top of old ones and are used as a means of producing new plants.

A reference to the orientation at an oblique angle to the soil surface.

Orientation at an oblique angle to the soil surface.

Of or relating to geopolitics.

A reference to a study of the influence of such factors as geography, economics, and demography on the politics and especially the foreign policy of a state or country.

A specialist in geopolitics; such as, a combination of political and geographic factors relating to something (as a country or particular resources).

1. The study of the relationships among politics and geography, demography, and economics; especially, with respect to the foreign policy of a nation.
2. The influence of geographic factors, population distribution, and natural resources on a nation's foreign policy; that is, the efforts of a nation to control a canal, trade route, oil supply, etc.
3. A combination of geographic and political factors relating to or influencing a nation or region.

Of or relating to agriculture.

1. Cultivating plants in earth.
2. The study or science of agriculture.

The gravity potential of the earth; the sum of its gravitational potential and the potential of its centrifugal force, in which the zero point of energy is defined to be located at sea level.

Pressure beneath the surface of the earth; especially, a pressure of greater than usual strength existing in a subsurface formation; for example, a fluid deposit that is under very high pressure because it carries part of the overburden load.

Simply stated: The pressure within the earth, or formation pressure.
