AP Human Geography Unit 1: The Spatial Perspective

Vocabulary-style flashcards covering the key concepts, map types, geospatial technologies, and diffusion patterns from Unit 1 of AP Human Geography.

Geography (Gritzner's Definition)

The study of "what is where, why there, and why care?"

Globalization

The process of the world becoming more integrated, uniform, and homogenized.

Tobler’s Law

The First Law of Geography which states, "Everything is connected, and closer things are more connected."

Free Response Question (FRQ) - Compare

A writing prompt requiring a description or explanation of similarities and/or differences.

Free Response Question (FRQ) - Explain

A writing prompt requiring information about how or why a relationship, process, pattern, position, or outcome occurs, using evidence and/or reasoning.

Cartographic Scale

The ratio between the size of an object on a map and its actual size on Earth's surface, represented by words, a ratio, or a line.

Large-scale maps

Maps that show a relatively small area with a high level of detail.

Small-scale maps

Maps that show a relatively large area with a low level of detail.

Reference maps

Maps designed for people to refer to for general information about places, such as political or physical maps.

Thematic maps

Maps that tell a story or show a specific variable, such as choropleth, dot distribution, or isoline maps.

Choropleth maps

Thematic maps that use colors or shading to represent different quantities or values within defined areas.

Isoline maps

Maps that use lines to connect points of equal value, commonly used for topographic or weather data.

Cartogram

A map that intentionaly distorts the size or shape of geographic areas to represent a specific variable.

Absolute location

The exact position of a place on Earth's surface, typically measured using latitude and longitude coordinates.

Relative location

The location of a place in relation to other places, often described in terms of connectivity and accessibility.

Distance Decay

The principle that the level of contact or interaction between two places decreases as the distance between them increases.

Friction of Distance

The measure of the restraining effect of distance on human movement and interaction.

Time-Space Compression

The reduction in the time it takes for something to reach another place due to improvements in technology and transportation.

Geospatial Data

Reliable data that includes information about a physical location, often categorized into quantitative and qualitative sources.

GPS (Global Positioning System)

A system of satellites and receivers used to determine the absolute location of a point on Earth.

GIS (Geographic Information System)

A computer system that captures, stores, analyzes, and displays layered geographic data.

Remote Sensing

The collection of data about Earth's surface from a distance, such as by satellite or aerial photography.

Geovisualization

The use of visual representations and modern technology to analyze and solve problems using geographic data.

Site

The physical characteristics of a place, such as climate, elevation, and water sources.

Situation

The location of a place relative to its surroundings and other places.

Toponym

The specific name given to a place on Earth's surface.

Environmental Determinism

The theory that the physical environment is the primary factor that shapes human culture and societal development.

Possibilism

The theory that the physical environment may set limits, but humans have the ability to adjust and choose their own cultural path.

Sustainability

The practice of using Earth’s resources in a way that provides for current needs without compromising the ability of future generations to meet theirs.

Cultural Landscape

The visible imprint of human activity and culture on the physical landscape.

Aggregation

The level of detail or the geographic scale at which data is grouped or analyzed.

Formal Region

Also known as a Uniform Region, an area where everyone shares one or more common characteristics.

Functional Region

Also known as a Nodal Region, an area organized around a central node or focal point.

Vernacular Region

Also known as a Perceptual Region, an area that people believe exists as part of their cultural identity.

Hearth

The specific location or origin point from which an idea, innovation, or feature spreads.

Relocation Diffusion

The spread of an idea through the physical movement of people from one place to another.

Contagious Diffusion

A type of expansion diffusion where an idea or trend spreads rapidly and outward in all directions from its source.

Hierarchical Diffusion

A type of expansion diffusion where an idea spreads from a person or node of authority or power to other persons or places.

Stimulus Diffusion

A type of expansion diffusion where the underlying principle of an idea spreads, even if the specific characteristic itself is modified.

Reverse Hierarchical Diffusion

The spread of an idea from lower-power or lower-population areas to higher-power areas, often seen in grassroots movements.
