AP Human Geography Unit 1 Vocabulary

Comprehensive vocabulary flashcards covering foundational geography concepts including maps, projections, spatial patterns, diffusion types, environmental theories, scales of analysis, and region types.

Reference maps

Maps designed for general informational purposes, showing location-based geographical features such as roads, boundaries, and landforms.

Thematic maps

Maps designed to show specific spatial patterns, data, or attributes organized around a particular theme or topic.

Absolute distance

The precise physical distance measured between two points using standard units such as miles or kilometers.

Relative distance

A measure of distance between places determined by social, cultural, or economic connectivity, often expressed in time, cost, or travel effort.

Absolute direction

Direction determined using fixed, cardinal directions such as North, South, East, and West.

Relative direction

Direction described based on spatial relationships and context, using terms like left, right, up, down, forward, or backward.

Elevation

The height of a location or physical landform measured above or below a fixed reference level, typically sea level.

Map projections and distortions

Methods of transferring the spherical surface of the Earth onto a flat surface, which inherently distorts shape, area, distance, and direction.

Robinson Projection

A projection that maintains overall shapes and relative positions without extreme distortion. Most used by college board.

Mercator projection

Best map for direction, nor good for accurate size distinction

Polar projection

Map looked at from the poles, very rare.

Geographic information systems (GIS)

Computerized technology systems used for capturing, storing, analyzing, displaying, and layering spatial and geographical data.

Remote sensing

The gathering and acquisition of data about Earth's surface from a distance using sensors mounted on satellites or aircraft.

GPS

Global Positioning System; a satellite-based system used to determine precise coordinates, location, and time anywhere on Earth.

Absolute location

The exact physical spot of a feature on Earth defined by precise geographic coordinates such as latitude and longitude.

Relative location

The position of a place described in relation to other surrounding places or geographic features.

Space

The geometric surface or area in which physical objects and human activities exist, arranged, and interact.

Clustered distribution

A spatial arrangement where objects, features, or phenomena are grouped closely together in space.

Dispersed distribution

A spatial arrangement where objects, features, or phenomena are spread out or widely scattered across space.

Diffusion

The spatial process by which a feature, innovation, idea, or cultural trait spreads across space over time.

Relocation diffusion

The spread of an idea, innovation, or cultural trait through the physical movement of people from one place to another.

Expansion diffusion

The spread of a feature or trait among people across space in a cumulative process while remaining strong at its origin hearth.

Stimulus diffusion

A type of expansion diffusion where a basic underlying idea or principle spreads and is adopted, but modified or adapted into a new form by the receiving group.

Hierarchical diffusion

A type of expansion diffusion where an idea or innovation spreads through a structured chain of command or nodes of influence, such as from major cities or key leaders.

Reverse hierarchical diffusion

A type of expansion diffusion where a feature or trait spreads from small, rural, or low-status places or groups up to larger cities or influential elites.

Contagious diffusion

A type of expansion diffusion characterized by rapid, widespread, continuous contact and diffusion throughout a population without regard to hierarchy.

Place

A specific point on Earth distinguished by its unique physical and human characteristics, conferring individual identity and meaning.

Distance decay

The principle stating that interaction or connectivity between two places diminishes as the distance between them increases.

Time-space compression

The reduction in time it takes for something to reach another place due to technological advancements in transportation and communication.

Environmental determinism

The historic theory asserting that the physical environment, climate, and geography strictly dictate and shape human cultural and societal development.

Possibilism

The theory that while the physical environment imposes limits, humans possess the agency to adapt and choose among various possibilities to overcome environmental conditions.

Scales of analysis

The geographic levels at which spatial data and patterns are observed and analyzed, including global, regional, national, and local scales.

Formal region

A geographic area defined by uniform, shared physical, cultural, or administrative characteristics across its entire extent.

Functional region

A geographic area organized around a central focal node and connected by economic, communication, or movement systems.

Perceptual/vernacular region

A geographic area based on people's personal informal beliefs, feelings, attitudes, and mental maps rather than strict objective boundaries.
