AP Human Geography Unit 1 Vocabulary Flashcards

A complete set of vocabulary flashcards covering key topics from Unit 1 of AP Human Geography, including spatial concepts, regions, scales, diffusion, and map projections.

Geography

The study of where things are located, why they are there, and how places and people interact.

Absolute Location

The exact location of something, such as latitude and longitude or GPS coordinates.

Relative Location

Where something is located in relation to something else.

Place

The physical and human characteristics of a location.

Physical Characteristics

Natural features of a location including climate, landforms, vegetation, and bodies of water.

Human Characteristics

Culture and human-made features of a location including language, religion, architecture, population, culture, and economy.

Region

An area that shares one or more characteristics.

Formal Region

A region (also known as uniform) that has a clearly defined common characteristic that is measurable or observable.

Perceptual Region

A region based on people's ideas, feelings, or perceptions about an area, whose boundaries are often not clearly defined.

Nodal Region

A region (also called a functional region) organized around a central point, or node, with the surrounding area connected to that node.

Clustered

A spatial pattern where things are grouped together.

Dispersed

A spatial pattern where things are spread out.

Linear

A spatial pattern where things are arranged along a line.

Density

A spatial concept that measures how much of something exists in a given area.

Concentration

A spatial concept describing how clustered or spread out something is.

Pattern

A spatial concept describing how things are arranged.

Map Scale

The relationship between distance on a map and distance in the real world.

Scale of Analysis

The geographic level (such as local, regional, national, or global) at which data are examined.

Scale of Inquiry

The geographic level at which a question is asked.

Spatial Interaction

Movement or interaction between different places, such as migration, trade, commuting, tourism, transportation, and communication.

Distance Decay

The principle that interaction generally decreases as distance increases.

Time-Space Compression

The process where technology and transportation reduce the time needed to travel or communicate, making places seem closer together.

Diffusion

The spread of ideas, culture, technology, diseases, or other phenomena from one place to another.

Relocation Diffusion

A type of diffusion where something spreads because people physically move and bring it with them.

Expansion Diffusion

A type of diffusion where an idea spreads outward from its origin while remaining strong in the original location.

Contagious Diffusion

A form of expansion diffusion that spreads rapidly through person-to-person contact.

Hierarchical Diffusion

A form of expansion diffusion where something spreads from important or influential people or places to others.

Stimulus Diffusion

A form of expansion diffusion where the basic idea spreads, but people modify it to fit their culture.

Map Projections

Attempts to represent the round surface of the Earth on a flat surface, which always results in some type of distortion.

S.A.D.D.

An acronym for Shape, Area, Distance, and Direction, which represent the four properties affected by map distortion.

Mercator Projection

A cylindrical map projection useful for navigation that preserves shape and direction but greatly exaggerates the size of areas near the poles.

Robinson Projection

A map projection that attempts to create a visually balanced representation of the entire Earth by reducing extreme distortion, though it does not perfectly preserve area, shape, distance, or direction.
