geo-, ge- +


Caenogaea, Cainogea, Kainogaea
1. A zoogeographical region which includes the Nearctic, Palearctic, and Oriental regions.
2. Etymology: Greek kainos, "recent" and gaia, "earth".
A biogeographical region including all of the neotropical region except temperate South America.
diageotropic (adjective), more diageotropic, most diageotropic
Relating to, or exhibiting a growth movement in a plant organ so that it assumes a position at right angles to the direction of gravity.
diageotropism (s) (noun), diageotropisms (pl)
1. The tendency of a sessile organism (leaf or flower that has no stalk but is attached directly to the stem), or structure, to grow horizontally to the ground or perpendicularly to the line of gravity; such as, a tree branch or root.
3. The tendency of growing parts; such as, roots, to become oriented at right angles to the direction of any gravitational force.
A reference to the geographical aspects of the ecology.
1. Living within or near the surface of the ground.
2. Relating to or being within, or inside, the environment under the surface of the ground.
1. Living on or near the surface of the ground.
2. Relating to or being the environment near the surface of the ground.
epigeotropic (adjective)
A description of the responses of plants on the surface of the earth toward the pull of gravity.
epigeotropism (s) (noun), epigeotropisms (pl)
Plant growth, or movement, on the surface of the earth in response to gravity.
The scientific study of the georaphic distribution of races, peoples, or cultural groups and their adaptations and relations to the environments in which they live.
field geology
The preparation of geological maps that show the distribution of geologic units selected for representation on a map.


A common objective is to interpret the structure at some depth below the surface of the earth.

It is possible to determine, with some degree of accuracy, the structure beneath the surface by using information available at the surface of the earth.

Gaia (Greek), Gaea, Terra, Tellus (Latin)
1. The "earth mother" or "mother earth".
2. A Gaia space craft that is on a "Gaia mission" whose main goal is to make the largest, most precise three-dimensional map of our Galaxy by surveying an unprecedented one per cent of its population of 100 billion stars.

Astronomers will have the challenge of dealing with a flood of data when Gaia begins its work in 2012. Even after being compressed by software, the data produced by the five-year mission will fill over 30 000 CD ROMs. This data will be transmitted "raw" and they will need processing on Earth to turn it into a calibrated set of measurements that can be freely used by the astronomical community.

geoacoustics (s) (noun) (a plural form that functions as a singular)
The use of echo-ranging devices with low-frequency seismographic waves transmitted several miles into the earth's crust to determine the composition and characteristics of the area: "Sam's cousin, Hanson, is a scientist who has developed unique techniques for the use of geoacoustics in his research about the minerals that exist below the surface of the ground."
geoaesthesia, geoesthesia (s) (noun); geoaesthesias, geoesthesias (pl)
The capacity of a plant to perceive and to respond to gravity: For her high school botany project, Haden studied the geoaesthesia of both land and water based plants.
The techniques of geology applied to archaeological issues; such as, dating methodology, mineral identification, soil and stratification analysis; the investigation of the relationship between archaeological and geological processes.

It is an ecological approach to archaeology with the goal of understanding the physical context of archaeological remains and the emphasis on the interrelationships among cultural and land systems.
