APHG Unit 1: Thinking Geographically

Simplified vocabulary terms and definitions for Chapter 1 (Thinking Geographically) of AP Human Geography. Focuses on maps, technology, regions, human-environment interaction, and spatial diffusion.

Absolute location

The exact spot of a place on Earth that never changes, like GPS coordinates.

Acculturation

When two cultures meet and borrow traits but both keep their original identities.

Assimilation

When a minority cultural group completely loses its original traits and blends in.

Behavioral geography

The study of psychological reasons behind why individuals choose to act or move.

Cartography

The science and art of mapmaking.

Choropleth map

A map using different shades or colors to show data values.

Climate

The regular, long-term pattern of weather in a specific place over many years.

Concentration

How closely packed together or spread apart things are across an area.

Connection

The bonds and relationships that link different people and objects across a distance.

Conservation

Using and managing natural resources wisely so they do not run out.

Contagious diffusion

The rapid, wave-like spread of an idea or trend through a population.

Coordinated Universal Time (UTC)

The master time zone at 0° longitude used as the official world standard.

Cultural ecology

The study of how human cultures interact with and adapt to their environment.

Cultural landscape

The visible imprint that humans leave on nature, including buildings and roads.

Culture

The collection of beliefs, traditions, behaviors, and objects shared by a group.

Density

The exact number of times something exists within a specific measurement of space.

Diffusion

The process of an idea, trend, or item spreading from one place to another.

Distance decay

The rule that connection decreases as distance between two things increases.

Distribution

The way things are arranged and spaced out across the Earth's surface.

Dot distribution map

A map that uses dots to show exactly where individual data pieces are.

Environmental determinism

The theory that the physical environment completely controls and dictates human culture.

Expansion diffusion

The spread of a trend where the idea grows bigger outward from its start.

Formal region (uniform region)

An area where everyone shares a common, matching trait like language or law.

Functional region (nodal region)

An area kept together by a central hub and movement around it.

Geographic information science (GIScience)

The deep scientific study and development of digital mapping technologies.

Geographic information system (GIS)

A computer program used to stack, analyze, and display layers of map data.

Geotagging

Adding digital GPS coordinates to media to show exactly where it was made.

Global Positioning System (GPS)

A navigation system using satellites to pinpoint exact absolute location on Earth.

Globalization

The process of ideas, businesses, and cultures spreading worldwide and interconnecting.

Graduated symbol map

A map where icons grow larger or smaller depending on data values.

Hearth

The exact birthplace or starting point where a new idea begins.

Hierarchical diffusion

The spread of a trend from powerful people or nodes down to others.

Humanistic geography

Geography centered on personal meanings, memories, and emotional connections to places.

Isoline map

A map that connects points of equal value with lines.

Latitude

Horizontal lines measuring distance north or south of the Equator.

Location

The specific position of something on the surface of the Earth.

Longitude

Vertical lines measuring distance east or west of the Prime Meridian.

Map

A flat, two-dimensional model or drawing of the Earth's surface.

Map scale

The ratio comparing map distance to actual distance in the real world.

Mashup

A digital map created by overlaying data from one source onto another.

Mental map

A personal map inside someone's head based on memories and opinions.

Meridian

An arc or vertical line running from pole to pole (longitude line).

Network

A system or chain of communication paths connecting different places.

Nonrenewable resource

A natural resource that forms so slowly it cannot be replaced once used.

Parallel

A horizontal circle drawn around the globe that never crosses another (latitude).

Place

A unique point on Earth outstanding due to specific physical or human traits.

Polder

A piece of low-lying land reclaimed from the sea by pumping water out.

Possibilism

The theory that nature sets limits, but humans can adapt and overcome.

Prime meridian

The starting line of 0° longitude running through Greenwich, England.

Region

Any area of Earth grouped together because it shares unique features.

Relocation diffusion

The spread of an idea through physical movement of people to new places.

Remote sensing

Gathering data about Earth from a distance using satellites or drones.

Renewable resource

A natural resource that replaces itself faster than humans can consume it.

Resource

Anything in nature useful to humans, legally accessible, and affordable to obtain.

Scale

The size level studied, ranging from local neighborhoods to the global planet.

Site

The exact physical characteristics of a place, like climate, water, or elevation.

Situation (relative location)

Where a place is located compared to other well-known places around it.

Space

The physical gap, distance, or interval between two distinct objects.

Spatial association

When two different things are distributed on a map in a matching pattern.

Stimulus diffusion

When a main idea spreads but must be tweaked to fit local culture.

Sustainability

Using resources carefully today so that future generations will have enough left.

Syncretism

Blending traits from two different cultures to create a brand-new cultural feature.

Toponym

The official name given to a specific place on Earth.

Vernacular region (perceptual region)

A place defined by stereotypes and personal feelings rather than official borders.

Volunteered geographic information (VGI)

Free geographic data created and shared online by everyday people.
