geo-, ge- +
(Greek: earth, land, soil; world; Gaia (Greek), Gaea (Latin), "earth goddess")
2. Someone who scientifically studies the surface of the earth, including such aspects as its climate, topography, vegetation, and population; as well as, the effects on the earth's surface of human activities.
2. Concerning the topography of a specific region.
2. An organized collection of computer hardware, software, geographic data, and personnel designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information which can be drawn from different sources, both statistical and mapped.
3. Computer programs linking features commonly seen on maps; such as, roads, town boundaries, and water bodies, with related information not usually presented on maps; for examlple, type of road surface, population, type of agriculture, type of vegetation, or water quality information.
GIS is a unique information system in which individual observations can be spatially referenced to each other.4. A technology that is used to view and analyze data from a geographic perspective. The technology is a piece of an organization's overall information system framework.
GIS links locations to information; such as, people to addresses, buildings to parcels of land, or streets within a network, and layers that information to give a better understanding of how it all interrelates. The user can than choose which layers to combine based on his/her purpose.
There's more information at the Geographic Information System (GIS): Index
"Differentiation of populations of biological groups in various geographical isolations to the point where they are recognized as separate species."
2. In general, the terms geographic and geographical are interchangeable, and compound terms listed here as beginning with one form can also be written with the other form.
2. An area of land that can be considered as a unit for the purposes of some geographical classification.
Plant geography has emphasized the mapping of such regions and the interpretation of the terms of environmental (ecological) influences.
The areas of Phytogeography and zoogeography do not necessarily exist together in the same place, because there are barriers and factors that affect their growth and arrangements which are often different for plants and for animals.
It often contains a small round lake, and it may, or may not, be occupied by ice or snow.
2. The quantities of latitude and longitude which define the position of a point on the surface of the earth with respect to the reference spheroid.
This theory suggests that landscapes go through three stages of development (youth, maturity, and old age) and indicates that the rejuvenation of landscapes arises from tectonic uplift of the land.
In the "youthful stage", under the influence of tectonic uplifts, there appears a mountain relief, which is dissected through erosion (the washing out of rocks by rivers) into deep, narrow valleys and sharp-peaked ridges.
With the dissection by streams, the area would reach maturity and, ultimately, would be reduced to an old-age surface called a peneplain (gently undulating, almost featureless plain), with an elevation near sea level.
The model developed by Davis, though important in historical context, is currently considered only a first approximation.
Developments in the sciences of geology and geomorphology, especially the plate tectonics revolution of the 1960's and 1970's, have confirmed the preliminary nature of the model.
