geo-, ge- +

Apparently fixed in position in relation to the earth; describing an artificial satellite that travels above the equator and at the same speed as the earth rotates; so, that it constantly appears at the same point in the sky.

Relating to the deflective forces produced by, or arising from, the earth's rotation.

A wind, ocean current, or other such movement in which the horizontal force is exactly balanced by the apparent force exerted on a moving object by the rotation of the earth.

The balance between the Coriolis force and the horizontal pressure gradient that determines the first-order circulation patterns of the open ocean.

The Coriolis force is an apparent force exerted on a moving object by the rotation of the earth; an object that is moving horizontally above the earth's surface in the Northern Hemisphere tends to show a rightward deflection, and one in the Southern Hemisphere tends to show a lefward deflection.

Described by Gaspard de Coriolis, 1792-1843, A French civil engineer.

A reference to a satellite which has an orbit which appears to be fixed in a position related to the earth that does not necessarily lie in the earth's equatorial plane as it is when it is geostationary.

Any equatorial satellite with an orbital velocity equal to the rotational velocity of the earth resulting in a satellite that is apparently motionless for any observer on the earth.

A geosynchronous satellite has an orbit similar to a geostationary one, except that it does not necessarily lie in the earth's equatorial plane.

An extensive, basin-shaped, mobile downward subsidence of the earth's crust, caused by the deposition of considerable thicknesses of sedimentary and volcanic rocks over millions of years.

Referring to the movement of a motile organism using the earth's gravity for orientation.

1. A locomotor movement by an animal in response to a gravitational stimulus.
2. Taxis of an animal in response to gravitational forces.
3. A directed response of a motile organism towards (positive) or away from (negative) the direction of gravity; in other words, a movement of a motile micro-organism or cell in response to the force of gravity.

1. The art of modifying and adapting the physical nature of the earth to the needs of humans.
2. The application of scientific methods and engineering principles to civil engineering problems through acquiring, interpreting, and using knowledge of materials of the crust of the earth.
3. Research that leads to increasing the habitability of the earth.

The application of scientific methods and engineering techniques to the exploitation and utilization of natural resources; such as, mineral resources.

1. Of or relating to the shape, structure, and arrangement of the rock masses resulting from structural deformation of the earth's crust.
2. Relating to the form, arrangement, and structure of rock masses of the earth's crust resulting from folding or faulting.

Relating to the large-scale structure of the earth's crust.

1. Relating to, or caused by, the internal heat of the earth.
2. Describing an energy system that makes use of the internal heat produced by the earth.

The use of geothermal heat in agriculture; that is, the use of low-temperature geothermal water to warm irrigation water or to sterilize soil.
