AP Geography Vocab 1b

built environment

The man-made surroundings that provide the setting for human activity, ranging from buildings and roads to neighborhoods and parks.

density

The frequency with which something exists within a given unit of area (e.g., arithmetic, physiological, or agricultural density).

diffusion

The process by which a characteristic, feature, or innovation spreads across space from one place to another over time.

dispersed

A pattern in which objects or features in a given area are scattered or positioned relatively far apart from one another.

distance decay (friction of distance)

The diminishing in importance and eventual disappearance of a phenomenon with increasing distance from its origin.

distortion

The misrepresentation of shape, area, distance, or direction of geographic features when transferring them from a 3D sphere to a 2D flat map.

dot density maps

A map type that uses dots to represent the presence or frequency of a feature, conveying a visual impression of spatial density.

climate

The long-term average weather conditions and patterns observed in a specific region over an extended period.

cultural ecology

A geographic approach that emphasizes human-environment relationships and how different cultures adapt to and alter physical environments.

cultural landscape

The fashioning of a natural landscape by a cultural group, reflecting their values, identity, built structures, and history.

culture

The body of customary beliefs, social forms, material traits, and shared traditions that together constitute a group's distinct identity.

environmental determinism

A 19th-century geographical approach arguing that the physical environment directly causes and dictates human activities and social development.

field observations

The process of physically visiting a location, region, or place to record data, map features, and observe geographic phenomena firsthand.

Flow (diffusion)

The movement of people, ideas, goods, or information from one location to another across space, facilitating spatial interaction.

formal region

An area in which everyone shares in common one or more distinctive, measurable physical or cultural characteristics (also called a uniform region).

functional regions (nodal regions)

An area organized around a node or focal point, linked to that center by transportation, communication, or economic activity.

human-environmental interaction

The reciprocal ways in which humans modify, adapt to, and depend on the physical environment to fulfill their needs.

location

The position of anything on the Earth's surface, which can be expressed absolutely (exact coordinates) or relatively (in relation to other features).

map scale

The relationship between the size of an object or distance on a map and its actual size or distance on the Earth's surface.

mental map

An internal, personal representation of a portion of Earth's surface based on an individual's knowledge, impressions, and experiences of places.

perceptual regions (vernacular regions)

An area that people believe exists as part of their cultural identity or subjective mental map, lacking strict, official boundaries.

physical geography

The branch of geography dealing with natural features, environmental processes, and physical patterns of the Earth (e.g., landforms, climates).

place

A specific point on Earth distinguished by a particular physical and human character that gives it a unique identity.

Possibilism

The theory that the physical environment sets limits on human actions, but people have the cultural and technological ability to adjust and choose alternatives.

prime meridian

The meridian, designated as 0° longitude, that passes through the Royal Observatory at Greenwich, England, dividing East and West hemispheres Rhine.

qualitative data

Information that is descriptive, non-numerical, and subjective, often collected through interviews, descriptions, field notes, or visuals.

quantitative data

Information that can be measured, counted, and expressed numerically, typically analyzed using statistical and computational methods.

Region

An area of Earth's surface distinguished by a unique combination of shared cultural, physical, or functional features.

Regionalization

The process of dividing the Earth's surface into distinct areas (regions) based on specific criteria or characteristics to analyze spatial data.

sense of place

The unique state of mind, emotional attachment, or psychological meaning that individuals or groups associate with a specific geographic location.

site

The physical character of a place, including its absolute location factors like topography, climate, water sources, vegetation, and elevation.

situation

The location of a place relative to another place or surrounding human and physical features (relative location factors).

Space

The physical gap or interval between two objects, locations, or points across the Earth's surface.

Space-time compression

The reduction in the time it takes for something to reach another place, resulting from improved connectivity in transportation and communication.

spatial association

The degree to which things are similarly arranged or distributed over space; comparing two distributions to see if they follow a similar pattern.

subregions

Smaller, distinctive divisions within a larger geographic region that share specific traits separating them from the broader area.

sustainability

The use of Earth's renewable and nonrenewable natural resources in ways that ensure resource availability for future generations.

Toponyms

The names given to portions of Earth's surface, often reflecting the history, culture, or physical traits of a place (place names).

Transnational corporations

A large company that conducts research, operates factories, and sells products in multiple countries, rather than just its home base.

Vernacular region (perceptual)

An area defined by people's shared subjective perceptions and cultural identity rather than precise, formal geographic boundaries.
