Diffusion
The process of spread of a feature or trend from one place to another over time
Distance Decay
The diminishing in importance and eventual disappearence of a phenomnon with increasing distance from its origin
Distribution
The arrangement of something across Earth's surface
Environmental Determinism
A nineteenth- and early twentieth-century approach to the study of geography thast argued that the general laws sought by human geographers could be found in the phyisical sciences. Geography was therefore the study of how the phyisical environment caused human activities
Expansion Diffusion
The spread of a feature or trend among people from one area to another in a snowballing process
Formal Region
(or uniform or homogeneous region) An area in which everyone shares in one or more distinctive characteristics
Functional Region

Hearth
The region from which innovative ideas originate
Heirarchical Diffusion
The spread of a feature or trend from one key person or node of authority or power to other persons or places
International Date Line
An arc that for the most part follows 180° longitude, although it deviates in several places to avoid dividing land areas. When you cross the International Date Line heading east (toward America), the clock moves back 24 hours, or one entire day. When you go west (toward Asia), the calendar moves ahead one day.

Longitude
The numbering system used to indicate the location of meridians drawn on a globe and measuring distance east and west of the prime meridian (0°).
Map
A two-dimensional, or flat, representation of Earth's surface or a portion of it
Mental Map

Place
A specific point on Earth distinguished by a particular character.

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
The meridian, designated at 0° longitude, which passes through the Royal Observatory at Greenwich, England.
Principal Meridian

Scale
Generally, 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.
