Sequent occupance
The notion that successive societies leave their cultural imprints on a place, each contributing to the cumulative cultural landscape. This is an important concept in geography because it symbolizes how humans interact with their surroundings.
Cultural landscape
Fashioning of a natural landscape by a cultural group. This is the essence of how humans interact with nature.
Arithmetic density
The total number of people divided by the total land area. This is what most people think of as density; how many people per area of land.
Physiological density
The number of people per unit of area of arable land, which is land suitable for agriculture. This is important because it relates to how much land is being used by how many people.
Hearth
The region from which innovative ideas originate. This relates to the important concept of the spreading of ideas from one area to another (diffusion).
Diffusion
The process of spread of a feature or trend from one place to another over time.
Relocation diffusion
The spread of an idea through physical movement of people from one place to another. Ex: spread of AIDS from New York, California, & Florida.
Expansion diffusion
The spread of a feature from one place to another in a snowballing process. This can happen in 3 ways:
1.Hierarchical
2.Contagious
3.Stimulus
Hierarchical diffusion
The spread of an idea from persons or nodes of authority or power to other persons or places (Ex: hip-hop/rap music)
Contagious diffusion
The rapid, widespread diffusion of a characteristic throughout the population. (Ex: ideas placed on the internet)
Stimulus diffusion
the spread of an underlying principle, even though a characteristic itself apparently fails to diffuse. (Ex: PC & Apple competition, p40)
Absolute distance
Exact measurement of the physical space between two places.
Relative distance
Approximate measurement of the physical space between two places.
Distribution
The arrangement of something across Earth's surface.
Site
The physical character of place; what is found at the location and why it is significant
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 system.
Friction of Distance
is based on the notion that distance usually requires some amount of effort, money, and/or energy to overcome. Because of this "friction," spatial interactions will tend to take place more often over shorter distances; quantity of interaction will decline
Spatial Distribution
Physical location of geographic phenomena across SPACE
