TermDefinition
absolute location Absolute location is a way of describing the position of an object or place, perhaps on the surface of the earth.
agricultural density The total rural population / area of arable land-meaning land that can be used for growing crops
arithmetic density the total number of people divided by the total land area.
cartography the science or practice of drawing maps.
concentration the frequency with which something occurs in space (can be measures of people, houses, cars, volcanoes, or anything, with any method of measurement)
contagious diffusion the distance-controlled spreading of an idea, innovation, or some other item through a local population by contact from person to person.after direct contact between the innovator and potential adapters of an innovation
cultural ecology the relationship between a given society and its natural environment as well as the life-forms and ecosystems that support its lifeways
culture the arts and other manifestations of human intellectual achievement regarded collectively.
diffusion the movement of ideas, notions, and innovations
density the frequency with which something occurs in space (can be measures of people, houses, cars, volcanoes, or anything, with any method of measurement)
distance-decay A function that represents the way that some entity or its influence decays with distance from its geographical location.
distribution Arrangement of features in space; three main properties: density, concentration, pattern
environmental determinism how the physical environment caused social development, applying laws from the natural sciences to understanding relationships between the physical environment and human actions
equator an imaginary line drawn around the earth equally distant from both poles, dividing the earth into northern and southern hemispheres and constituting the parallel of latitude 0°.
expansion diffusion the spread of an innovation or an idea through a population in an area
friction of distance A measure of how much absolute distance affects the interaction between 2 places.
globalization growth to a global or worldwide scale
hierarchical diffusion A form of expansion diffusion in which an innovation spreads over space from large places to progressively smaller ones, skipping the spaces in between.
hearth (node) the place where diffusion starts.
international date line An arc that for the most part follows 180° longitude. When you cross the International Date Line heading east, the clock moves back 24 hours, or one entire day. When you go west, the calendar moves ahead one day.
latitude the angular distance of a place north or south of the earth's equator, or of a celestial object north or south of the celestial equator, usually expressed in degrees and minutes.
longitude the angular distance of a place east or west of the meridian at Greenwich, England, or west of the standard meridian of a celestial object, usually expressed in degrees and minutes.
pattern The geometric or regular arrangement of something in a sturdy area.
physiological density number of persons per unit of area suitable for agriculture. Could mean a country has difficulty growing enough food.
possibilism The theory that the physical environment may set limits on human actions, but people have the ability to adjust to the physical environment and choose a course of action from many alternatives
prime meridian a planet's meridian adopted as the zero of longitude.
projection The system used to transfer locations from Earth's surface to a flat map
region An area distinguished by a unique combination of trends or features
relative location location of a place with respect to other places
relocation diffusion sequential diffusion process in which the items being diffused are transmitted by their carrier agents as they evacuate the old areas and relocate the new ones
scale the relationship between the portion of Earth being studied and Earth as a whole, specifically the relationship between the size of an object on a map and the size of the actual feature on Earth's surface.
site The physical character of a place
situation The location of a place relative to other places
space-time compression The reduction in the time it takes to diffuse something to a distant place, as a result of improved communications and transportation systems
spatial analysis patterns of human behavior and its spatial expression in terms of mathematics and geometry; that is, locational analysis.
stimulus diffusion underlying principle of a characteristic spreads although characteristic failed.
time zones new time zone for every 15 degrees west/ 24 time zones/ allows time to follow with rotation of earth ex: noon- when sun is highest in the sky
toponym the name by which a geographical place is known
transnational corporation A company that conducts research, operates factories, and sells products in many countries
uneven development The increasing gap in economic conditions between core and peripheral regions as a result of the globalization of the economy.
