geo-, ge- +

(Greek: earth, land, soil; world; Gaia (Greek), Gaea (Latin), "earth goddess")

1. The scientific study of the chemistry of the earth, including the rocks, sediments, and soil that constitute the solid earth and the fluids that compose the ocean, inland waters, and the atmosphere.
2. Referring to chemical reactions involving earth materials; such as, soil, rocks, and water.
3. The chemistry of the composition and alterations of the solid matter of the earth or a celestial body.

The study of the chemistry of the earth includes the study of the rocks and sediments that constitute the solid earth; as well as, the fluids of the oceans, inland waters, and atmosphere.

Geochemistry is based on a foundation of other sciences, including chemistry, geology, physics, and biology. This field of research includes the study of the movement, or flux, of chemical elements through the solids and fluids of the earth.

A reference to the chronology, or time sequences, of the earth's history as determined by geological events.
Someone who studies the chronology, or time periods, of the earth, as based on both absolute and relative methods of age determination.
1. The chronology of the earth; that is, the measurement of geological time and the ordering of past geological events.
2. The time sequence of the earth’s history as governed by geological events.
3. The science of dating and the study of time in relation to the earth's history as revealed by geological data.
A reference to the measurement of an interval of time in relation to the history of the earth, using absolute or relative dating techniques.
1. An extension of geometry conceived as taking time into account as the fourth dimension; the geometry of space-time.
2. Absolute geochronology, in which events are assigned (approximate) dates in relation to the present instead of to other events.
3. Measurement of geologic time, as through isotopic-radioactive decay.
1. A usually elongated, basinlike depression along the edge of a continent, in which a thick sequence of sediments and volcanic deposits has accumulated.
2. A part of the earth's crust which is subjected to downward warping during a large span of geological time.
1. The practice of matching standardized tabular data (organized as a table or list) to a specific real world location with established geographical coordinates.
2. The process of assigning geographic identifiers (for example, codes or geographic coordinates expressed as latitude-longitude) to map features and other data records; such as, street addresses.

You can also geocode media; for example, where a picture was taken, IP addresses (Internet Protocol address or a numerical label), and anything that has a geographic component.

With geographic coordinates the features can be mapped and entered into Geographic Information Systems.

geocole (verb), geocoles; geocoled; geocoling: soil, ground
To spend the egg, or larval, stage in the ground: "Flies, beetles, or moths are examples of creatures that geocole."
geocolous (adjective); more geocolous, most geocolous
Living in the soil for part of a life cycle or period of time.
geocorona (s) (noun), geocoronas (pl)
1. The outermost region of the earth's atmosphere, reaching to a height approximately 15 times the radius of the earth and consisting mainly of hydrogen.
2. An envelope of ionized gases, mainly hydrogen, which encircles the earth to about 15 earth radii and emits Lyman-alpha radiation in the presence of sunlight which refers to a radiation emitted by hydrogen associated with the spectral line in the Lyman series (group of lines in the ultraviolet spectrum of hydrogen) whose wavelength is 121.5 nanometers.
The study of the origin of the earth.
The study of the geological origin and history of the earth.
geocratic (adjective), more geocratic, most geocratic
1. A reference to earth-movements that reduce the area of the earth's surface covered by water.
2. Of or pertaining to the predominant influence of the natural environment on humans.
3. Relating to times or conditions in which land expands or continents enlarge.
1. A lead-gray or grayish blue mineral with a metallic luster, consisting of sulphur, antimony, and lead, with a small proportion of arsenic.
2. A white or greenish-white, opaque, metallic, monoclinic mineral usually occurring in massive, granular form, having a specific gravity of 6.4 and a hardness of 2.5 on the Mohs scale.

A scale for classifying minerals based on relative hardness, determined by the ability of harder minerals to scratch softer ones.

The scale includes the following minerals listed in order from the softest to the hardest:

  1. talc
  2. gypsum
  3. calcite
  4. fluorite
  5. apatite
  6. orthoclase
  7. quartz
  8. topaz
  9. corundum
  10. diamond
