A

The study of the spatial variation in the patterns and processes related to human activity.

34
Q

International Date Line

A

The line of longitude that marks where each new day begins, centered on the 180th meridian.

35
Q

Intervening opportunity

A

If one place has a demand for some good or service and two places have a supply of equal price and quality, the supplier closer to the buyer will represent an intervening opportunity, thereby blocking the third from being able to share its supply of goods or services. Intervening opportunities are frequently used because transportation costs usually decrease with proximity.

36
Q

Isoline

A

A map line that connects points of equal or very similar values.

37
Q

A

A relatively small ratio between map units and ground units. Large-scale maps usually have higher resolution and cover much smaller regions than small-scale maps.

Q

Latitude

A

The angular distance north or south of the equator, defined by lines of -latitude or parallels.

39
Q

Law of Retail Gravitation

A

A law stating that people will be drawn to larger cities to con- duct their business since larger cities have a wider influence on the surrounding hinterlands.

40
Q

Location charts

A

On a map, a chart or graph that gives specific statistical information about a particular political unit or jurisdiction.

41
Q

Longitude

A

The angular distance east or west of the Prime Meridian, defined by lines of longitude, or meridians.

42
Q

Map projection

A

A mathematical method that involves transferring Earth’s sphere onto a flat surface. This term can also be used to describe the type of map that results from the process of projecting. All map projections have distortions in area, direction, distance, or shape.

43
Q

Map scale

A

The ratio between the size of an area on a map and the actual size of that same area on Earth’s surface.

44
Q

Mercator projection

A

A true conformal cylindrical map projection, the Mercator projection is particularly useful for navigation since it maintains accurate direction. Mercator projections are famous for their distortion in area that makes landmasses at the poles appear oversized.

45
Q

Meridian

A

A line of longitude that runs north-south. All lines of longitude are equal in length and intersect at the poles.

46
Q

Natural landscape

A

The physical landscape or environment that has not been affected by human activities.

47
Q

Parallel

A

An east-west line of latitude that runs parallel to the equator and that marks distance north or south of the equator.

48
Q

W. D. Pattison

A

Geographer who claimed that geography drew from four distinct traditions

49
Q

Perceptual region

A

Highly individualized definition of regions based on perceived com- monalities in culture and landscape.

50
Q

Peters Projection

A

An equal-area projection purposely centered on Africa in an attempt to treat all regions of Earth equally.

51
Q

Physical geography

A

The realm of geography that studies the structures, processes, distributions, and changes through time of the natural phenomena of Earth’s -surface.

52
Q

Preference map

A

A map that displays individual preferences for certain places.

53
Q

Prime meridian

A

An imaginary line passing through the Royal Observatory in Greenwich, England, that marks the 0° line of longitude.

A

The system used to transfer locations from Earth’s surface to a flat map.

A

A thematic map in which the size of a chosen symbol— such as a circle or triangle-indicates the relative magnitude of some statistical value for a given geographic region.

56
Q

Ptolemy

A

Roman geographer-astronomer, author of Guide to Geography, which included maps containing a grid system of latitude and longitude.

57
Q

Qualitative data

A

Data associated with a more humanistic approach to geography, often collected through interviews, empirical observations, or the interpretation of texts, artwork, old maps, and other archives.

58
Q

Quantitative data

A

Data associated with mathematical models and statistical techniques used to analyze spatial location and association.

59
Q

Reference map

A

A map type that shows reference information for a particular place, making it useful for finding landmarks and for navigation.

60
Q

Region

A

A territory that encompasses many places that share similar physical and/or cultural ttributes.

61
Q

Regional geography

A

The study of geographic regions.

62
Q

A

A measure of distance that includes the costs of overcoming the friction of absolute distance separating two places. Relative distance often describes the amount of social, cultural, or economic connectivity between two places. Relative location

63
Q

Relocation diffusion

A

The diffusion of ideas, innovations, behaviors, and so on from one place to another through migration.

64
Q

Remote sensing

A

The observation and mathematical measurement of Earth’s surface using aircraft and satellites. The sensors include photographic images, thermal images, multispectral scanners, and radar images.

65
Q

Resolution

A

A map’s smallest discernible unit. If, for example, an object has to be one kilometer long in order to show up on a map, that map’s resolution is one kilometer.

66
Q

Robinson Projection

A

A projection that attempts to balance several possible projection errors. It does not maintain area, shape, distance, or direction completely accurately, but it inimizes errors in each.

67
Q

Carl Sauer

A

Geographer from the University of California at Berkeley who defined the concept of cultural landscape as the fundamental unit of geographical analysis. This landscape results from the interaction between humans and the physical environment. Sauer argued that virtually no landscape has escaped alteration by human activities.

68
Q

Sense of Place

A

Feelings evoked by people as a result of certain experiences and memories associated with a particular place.

69
Q

Site

A

The absolute location of a place, described by local relief, landforms, and other cultural or physical characteristics.

70
Q

Situation

A

The relative location of a place in relation to the physical and cultural characteristics of the surrounding area and the connections and interdependencies within that system; a place’s spatial context.

71
Q

Small scale

A

A map scale ratio in which the ratio of units on the map to units on Earth is quite small. Small-scale maps usually depict large areas.

72
Q

Spatial diffusion

A

The ways in which phenomena, such as technological innovations, cultural trends, or even outbreaks of disease, travel over space.

73
Q

Spatial perspective

A

An intellectual framework that looks at the particular locations of a specific phenomenon, how and why that phenomenon is where it is, and, finally, how it is spatially related to phenomena in other places.

74
Q

Sustainability

A

The concept of using Earth’s resources in such a way that they provide for people’s needs in the present without diminishing Earth’s ability to provide for future generations.

75
Q

Thematic layers

A

Individual maps of specific features that are overlaid on one another in a Geographical Information System to understand and analyze a spatial relationship.

76
Q

Thematic map

A

A type of map that displays one or more variables such as population or income level-within a specific area.

77
Q

Time-Space Convergence

A

The idea that distance between some places is actually shrinking as technology enables more rapid communication and increased interaction among those places.

78
Q

Topographic maps

A

Maps that use isolines to represent constant elevations. If you took a topographic map out into the field and walked exactly along the path of an isoline on your map, you would always stay at the same elevation.

79
Q

Transferability

A

The costs involved in moving goods from one place to another.

80
Q
