grapho-, graph-, -graph, -graphy, -grapher, -graphia
(Greek: to scratch; to write, to record, to draw, to describe; that which is written or described)
As indicated at the bottom of this page, there is a significantly large number of graphic word-entry groups in this unit. Such an extensive listing is provided to show how important the grapho- element is to the English language.
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.
For example, there is the idea that a desert environment will produce a nomadic culture because desert terrain makes it easier for movement and the lack of consistent rainfall stimulates such movement.
The fundamental differences between land and ocean, latitudinal differences in insulation, spatial variations in receipts of precipitation, and patterns of geological composition, and deformation of the earth's crust together provide the basis for distinguishing definite geographical patterns of resource availability through out the world.
2. A computerized system which relates and displays data collected from a geographic entity in the form of a map.
The ability of a geographical information system to overlay existing data with new information and display it in color on a computer screen and is used primarily to conduct analyses and make decisions related to geology, ecology, land use, demographics, transportation, and other domains, most of which relate to the human use of the physical environment.
Through this process of geocoding, the geographic data from a database is converted into images in the form of maps.
2. A former name for nautical mile (sea mile) or a unit of length used in sea and air navigation, based on the length of one minute of arc of a great circle; especially, an international and U.S. unit equal to 1,852 meters (about 6,076 feet).
3. A unit of length in the US Customary System, used in air and sea navigation and equal to 6,076 feet or 2,025 yards (1,852 meters).
2. Any position on the surface of the earth defined by means of its geographical coordinates, either astronomical or geodetic; or expressed in terms of latitude and longitude, either geodetic or astronomical.
2. The total area occupied by a population.
3. The extreme distance at which an object or light can be seen when limited only by the curvature of the earth and the heights of the object and the observer.
2. An orderly arrangement of lines in which an area is defined in relation to one or more geographical points on the earth.
