TermDefinition
the study of the physical features of the earth and its atmosphere, and of human activity as it affects and is affected by these, including the distribution of populations and resources, land use, and industries. geography
a half of the earth, usually as divided into northern and southern halves by the equator, or into western and eastern halves by an imaginary line passing through the poles. hemisphere
an area that is designated by official boundaries. These areas are publicly known and include cities, towns, states, counties and countries. formal region
wear away or change the appearance or texture of (something) by long exposure to the air. weathering
the weather conditions prevailing in an area in general or over a long period. climates
a biological community of interacting organisms and their physical environment. ecosystems
the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms. biosphere
a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle. plate tectonics
qualities of a place character of a place
a point or place in relation to another point or place relative location
consist of a central place and the surrounding areas that are dependent upon that place, such as a metropolitan area functional region
collision or actually touching type of weathering mechanical weathering
the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes. chemical weathering
the envelope of gases surrounding the earth or another planet. atmosphere
any of the world's main continuous expanses of land (Africa, Antarctica, Asia, Australia, Europe, North America, South America). continent
the gradual movement of the continents across the earth's surface through geological time. continental drift
Absolute location describes the location of a place based on a fixed point on earth. The most common way is to identify the location using coordinates such as latitude and longitude. Lines of longitude and latitude crisscross the earth. absolute location
rain, snow, sleet, or hail that falls to the ground. precipitation
Perceptual regions are the third type of region. These regions reflect human feelings and attitudes about areas. These are very subjective, meaning that they are based more on opinions than facts. perceptual region
rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm, typically to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulfur and nitrogen o acid rain
the rigid outer part of the earth, consisting of the crust and upper mantle. lithosphere
all the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds. hydrosphere
a slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near the poles glacier
Also known as the circum-Pacific belt, the “Ring of Fire” is a 40,000 km (25,000 mile) horseshoe-shaped basin that is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. theory ring of fire
A geographic information system or geographical information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data. GIS
difference in height from the surrounding terrain; the amount of variation in elevation and slope in a particular area. relief
the region of the earth's interior between the crust and the core, believed to consist of hot, dense silicate rocks (mainly peridotite). mantle
center of a planet core
wearing away of rock and soil erosion
particulate matter that is carried by water or wind and deposited on the surface of the land or the bottom of a body of water, and may in time become consolidated into rock. sediment
a loosely compacted yellowish-gray deposit of windblown sediment of which extensive deposits occur, e.g., in eastern China and the American Midwest. loess
a mass of rocks and sediment carried down and deposited by a glacier, typically as ridges at its edges or extremity. moraine
