Conservation

The sustainable use and management of Earth's natural resources to meet human needs such as food, medicine, and recreation is conservation.

6
New cards

Contagious Diffusion

Involves a form of expansion in which people near the point of origin become adopters of a cultural fad.

7
New cards

Cultural Landscape

The visible reflection of a society, including their cultural beliefs and practices, on the physical environment.

8
New cards

Culture

A total way of life held in common by a group of people, including learned features such as language, ideology, behavior, technology, and government.

9
New cards

Density (Of Population)

Refers to the number of people who live in a defined land area (usually square miles or square kilometers).

10
New cards

Diffusion

The spread of an idea or characteristic over time.

11
New cards

Distance Decay

The theory that states that as the distance between two places increases, the interaction between those two places decreases.

New cards

Enclave

A state that is completely surrounded by another state.

13
New cards

Exclave

A region of a country that is completely separated from the main body of that country, usually by the borders of another country.

14
New cards

Expansion Diffusion

When innovations spread to new places while staying strong in their original locations.

15
New cards

Formal/Uniform Region

Homogenous areas where everyone in that region shares common attributes or traits like language, climate, or political system.

16
New cards

Functional/Nodal Region

Defined by a social or economic function that occurs between a node or focal point and the surrounding areas.

17
New cards

Geographic Information Science (GIScience)

The basic research field that seeks to redefine geographic concepts and their use in the context of geographic information systems.

18
New cards

Geographic Information Systems (GIS)

A computer system that analyses and displays geographically referenced information.

19
New cards

Global Positioning System (GPS)

A space-based radio-navigation system consisting of a constellation of satellites broadcasting navigation signals and a network of ground stations and satellite control stations used for monitoring and control.

20
New cards

Globalization

Refers to the homogenizing impact on local culture and economics caused by increased interaction between geographically distinct regions.

21
New cards

Hearth

The region from which innovative ideas originate.

22
New cards

Hierarchical Diffusion

The spreading of culture via a hierarchy "vertically" either from the top to the bottom or vice versa.

23
New cards

Infrastructure

The basic physical and organizational structures needed for a society to function.

24
New cards

Interdependence

Collective actions by people within a territory to gain political freedom and sovereignty, typically from a larger political entity.

25
New cards

Local Scale Analysis

Geographers describe the distinctive site or physical character of each place on earth.

26
New cards

Map

A symbolic representation of selected characteristics of a place, usually drawn on a flat surface.

27
New cards

Map Projection

The representation on a plane surface of any part of the surface of the Earth or a celestial sphere.

28
New cards

Metropolitan Area

Includes an urbanized area with a high population of at least 50,000 with high density adjacent countries where the majority of inhabitants work in nonagricultural jobs.

29
New cards

National Scale Analysis

Examining geographic phenomena and issues at the level of an entire nation or country.

30
New cards

Pattern

The arrangement of objects on Earth's surface in relation to other objects.

31
New cards

Preservation

The maintenance of resources in their present condition, with as little human impact as possible.

32
New cards

Region

Any area differentiated from surrounding areas by at least one characteristc.

33
New cards

Regional Scale Analysis

Involves analysis geographic data within distinct areas characterized by certain unifying features which as climate, culture, language, etc., which could be part of one country or span multiple countries.

34
New cards

Relative Location

A description of how a place is related to other places.

35
New cards

Relocation Diffusion

The spread of an idea or characteristic over time. When people move, or relocate, they spread ideas along with them.

36
New cards

Remote Sensing

The process of taking pictures of the Earth's surface from satellites to provide a greater understanding of the Earth's geography over large distances.

37
New cards

Reverse Hierarchical Diffusion

A type of expansion diffusion in which ideas spread from area to area by ways of small towns, temporarily bypassing urban areas.

38
New cards

Scale

The ratio between the portion of Earth being studied and Earth as a whole.

39
New cards

Scale Of Analysis

Includes global, regional, national, and local. Patterns and processes at different scales reveal variations in, and different interpretations of data.

40
New cards

Sense Of Place

A way to characterize the relationship between people and their spatial settings.

41
New cards

Site

The physical characteristics of an absolute location.

42
New cards

Situation

Where something is in relation to other locations/areas.

43
New cards

Spatial Patterns

An analytical tool used to measure the distance between two or more physical locations/items.

44
New cards

Stimulus Diffusion

The alteration of a characteristic as it spreads from one location to another; the alteration often occurs to better fit the new culture.

45
New cards

Sustainability

The use of Earth's resources in ways that ensure their availability in the future.

46
New cards

Time Distance Decay

The effect of distance on cultural or spatial interactions; the interaction between two locations declines as the distance between them increases.

47
New cards

Time Space Compression

The reduction in the time it takes for something to diffuse to a distant location because of improved communication, technology, and transportation.
