a porous, water-bearing layer of rock, sand, or gravel below ground level

a major ecological community, including plants and animals, occupying an extensive earth area

(syn ecosphere) the thin film of air, water, and earth within which we love, including the atmosphere, surrounding and subsurface waters, and the upper reaches of the earth's crust
272desertification
extension of desertlike landscapes as a result of overgrazing, destruction of the forests, or other human-induced changes, usually in semiarid regions
273ecosystem
a population of organisms existing together in a small, relatively homogeneous area (pond, forest, small island) together with the energy, air, water, soil, and chemicals upon which it depends
274environment
surroundings; the totality of things that in any way may affect an organism, including both physical and cultural conditions; a region characterized by a certain set of physical conditions
275environmental pollution
the introduction into the biosphere of materials that because of their quantity, chemical nature, or temperature have a negative impact on the ecosystem or that cannot be readily disposed of by natural recycling processes
276fallowing
the practice of allowing plowed or cultivated land to remain uncropped or only partially cropped for one or more growing seasons
277greenhouse effect
heating of the earth's surface as shortwave solar energy passes through the atmosphere, which is transparent to it but opaque to reradiated long-wave terrestrial energy; also, increasing the opacity of the atmosphere through the addition of increased amounts of carbon dioxide and other gases that trap heat
278hazardous waste
discarded solid, liquid, or gaseous material that poses a substantial threat to human health or to the environment when improperly disposed of or stored
279hydrologic cycle
the natural system by which water is continuously circulated through the biosphere by evaporation, condensation, and precipitation
280icebox effect
the tendency for certain kinds of air pollutants to lower temperatures on earth by reflecting incoming sunlight back into space and thus preventing it from reaching (and heating) the earth
281limiting factor principle
the distribution of an organism or the structure of an ecosystem can be explained by the control exerted by the single factor (such as temperature, light, water) that is most deficient, that is, that falls below the levels required
282ozone
a gas molecule consisting of three atoms of oxygen formed when diatomic oxygen is exposed to UV radiation. In the upper atmosphere it forms a normally continuous, thin layer that blocks UV light; in the lower atmosphere it constitutes a damaging component of photochemical smog
283crop rotation
the annual alteration of crops that make differential demands on or contributions to soil fertility
284soil
the complex mixture of loose material including minerals, organic and inorganic compounds, living organisms, air, and water found at teh earth's surface and capable of supporting plant life
285soil erosion
the wearing away and removal of rock and soil particles from exposed surfaces by agents such as moving water, wind, or ice
286terracing
the practice of planting crops on steep slopes that have been converted into a series of horizontal steplike level plots
287toxic waste
discarded chemical substances that can cause serous illness or death
288antecedent boundary
a boundary line established before the area in question is well populated
289artificial boundary
(syn geometric boundary) a boundary without obvious physical geographic basis; often a section of a parallel of latitude or a meridian of longitude
290autonomous nationalism
movement by a dissident minority intent to achieve partial or total independence of territory it occupies from the state within which it lies
291centrifugal force
1. economic and social forces pushing households and businesses outward from central and inner-city locations OR 2. forces of disruption and dissolution threatening the unity of a state
292centripetal force
1. a force attracting establishments or activities to the city center OR 2. forces tending to bind together the citizens of a state
293compact state
a state whose territory is nearly circular
294consequent boundary
(syn ethnographic boundary) a boundary line that coincides with some cultural divide, such as religion or language
295containment
a guiding principle of US foreign policy during the Cold War period; to prevent or restrict the expansion of the Soviet Union's influence or control beyond its then existing limits

(1) the national or world districts of concentrated economic power, wealth, innovation, and advanced technology
(2) the heartland or nucleus of a state, containing its most developed area, greatest wealth, densest populations, and clearest national identity

the transfer of certain powers from the state central government to separate political subdivisions within the state's territory
298domino theory
a geopolitics theory made part of American containment (of the former Soviet Union) policy beginning in the 1950s. The theory maintained that if a single country fell under Soviet influence or control, its neighbors would likely follow, creating a ripple effect like a line of toppling dominos

the study of the geographical elements of the organization and results of elections
300elongated state
a state whose territory is long and narrow
