geodetic datum
The ellipsoid, geodetic datum, or spatial reference system (SRS) upon which the geographic coordinates given in decimalLatitude and decimalLongitude as based.
geographic distribution
This organism is known to be present in this location or region. Not exclusive; other regions may also be reported.
geographic range (size of area)
The total extent of the geographic range of an organism.
whole plant geophytic
georeference protocol
A description or reference to the methods used to determine the spatial footprint, coordinates, and uncertainties.
georeference remarks
Notes or comments about the spatial description determination, explaining assumptions made in addition or opposition to the those formalized in the method referred to in georeferenceProtocol.

glacial lake
A lake associated with a glacier.
glacial valley
A valley that contains, or contained, a glacier and was formed by glacial activity. Typically U-shaped in cross-section.
A large, slow moving river of ice, formed from compacted layers of snow, that slowly deforms and flows in response to gravity.
Gleysols are wetland soils that, unless drained, are saturated with groundwater for long enough periods to develop a characteristic gleyic colour pattern. This pattern is essentially made up of reddish, brownish or yellowish colours at ped surfaces and/or in the upper soil layer or layers, in combination with greyish/bluish colours inside the peds and/or deeper in the soil.
Behavior related to the expansion lateral surface of the body with the intention of increasing the wind resistance against the body and hence reducing the speed of falling.

gorstian age
International Chronostratigraphic Chart:
A depressed block of land bordered by parallel faults. A graben is the result of a block of land being downthrown producing a valley with a distinct scarp on each side. Grabens often occur side-by-side with horsts. Horst and graben structures are indicative of tensional forces and crustal stretching.

granular sediment
Sediment characterised by an average particle diameter between 2 and 4 mm.

A grassland biome is a terrestrial biome which includes, across its entire spatial extent, an unbroken layer of grasses (Gramineae), sedges (Cyperaceae) or rushes (Juncaceae).
grassland area
An area in which grasses (Graminae) are a significant component of the vegetation.
grassland soil
Gravel is an environmental material which is composed of pieces of rock that are at least two millimeters (2mm) in its largest dimension and no more than 75 millimeters.
gravel field
gravel pit
A quarry from which gravel is extracted.
