unit 1 vocab

Alright, let's get you started with the vocabulary for Unit 1 of AP Human Geography, which typically covers Thinking Geographically:

Basic Geographic Concepts:

* Geography: The study of the physical features of the earth and its atmosphere, and of human activity as it affects and is affected by these.

* Human Geography: The branch of geography dealing with how human activity affects or is influenced by the earth's surface.

* Physical Geography: The branch of geography dealing with natural features and processes.

* Spatial Perspective: Observing variations in geographic phenomena across space.

* Spatial Association: The degree to which things are similarly arranged in space.

* Distribution: The arrangement of something across Earth's surface.

* Density: The frequency with which something exists within a given unit of area.

* Concentration: The extent of a feature's spread over space.

* Clustered: Closely spaced together.

* Dispersed: Spread out.

* Pattern: The geometric arrangement of objects in space.

* Location: The position of anything on Earth's surface.

* Absolute Location: The precise spot where something is according to a system such as latitude and longitude.

* Relative Location: The position of a place or thing in relation to another place or thing.

* Place: A specific point on Earth distinguished by a particular character.

* Region: An area of Earth defined by one or more distinctive characteristics.

* Formal Region (Uniform Region, Homogeneous Region): An area within which everyone shares in common one or more distinctive characteristics.

* Functional Region (Nodal Region): An area organized around a node or focal point.

* Vernacular Region (Perceptual Region, Cognitive Region): An area that people believe exists as part of their cultural identity.

* Scale: The relationship between the portion of Earth being studied and Earth as a whole.

* Map Scale: The ratio of a distance on the map to the corresponding distance on the ground.

* Ratio/Fraction Scale: Shows the numerical ratio between distances on the map and Earth's surface (e.g., 1:100,000).

* Written Scale: Describes the relationship between map and Earth distances in words (e.g., "One centimeter equals ten kilometers").

* Graphic Scale (Bar Scale): Consists of a bar line marked to show distance on Earth's surface.

* Scale of Analysis: The level at which data is aggregated and examined (e.g., global, regional, national, local).

Geographic Tools & Technologies:

* Map: A two-dimensional, or flat, representation of Earth's surface or a portion of it.

* Reference Map: Maps that show the absolute location of places and geographic features.

* Thematic Map: Maps that tell a story about the degree of an attribute, the pattern of its distribution, or its movement.

* Choropleth Map: A thematic map that uses tones or colors to represent spatial data as average values per unit area.

* Dot Distribution Map: A thematic map that uses dots to show the precise location of one or more phenomena.

* Graduated Symbol Map (Proportional Symbol Map): A thematic map that uses symbols of different sizes to indicate different amounts of a variable.

* Isoline Map (Isopleth Map): A thematic map with lines that connect points of equal value.

* Cartogram: A thematic map that distorts the geographic size of areas in order to reflect a variable.

* Global Positioning System (GPS): A system that determines the precise position of something on Earth through a series of satellites, tracking stations, and receivers.

* Geographic Information System (GIS): A computer system that captures, stores, analyzes, and displays geographic data.

* Remote Sensing: The acquisition of data about Earth's surface from a satellite orbiting the planet or from other long-distance methods.

* Geotagging: The process of adding geographical identification metadata (such as latitude and longitude) to various media such as photographs, videos, websites, or SMS messages.

Human-Environment Interaction & Culture:

* Environmental Determinism: The view that the physical environment dictates human culture and societal development.

* Possibilism: The theory that the physical environment may set limits on human actions, but people have the ability to adjust to the environment and choose a course of action from many alternatives.

* Cultural Landscape: The visible imprint of human activity and culture on the land.

* Culture: The body of customary beliefs, social forms, and material traits that together constitute a group's distinct tradition.

* Cultural Hearth: A center where cultures originated and from which they later spread.

* Diffusion: The process by which a characteristic spreads across space from one place to another over time.

* Relocation Diffusion: The spread of an idea through physical movement of people from one place to another.

* Expansion Diffusion: The spread of a feature from one place to another in a snowballing process.

* Hierarchical Diffusion: The spread of an idea from persons or nodes of authority or power to other persons or places.

* Contagious Diffusion: The widespread diffusion of a characteristic throughout the population.

* Stimulus Diffusion: The spread of an underlying principle, even though a specific characteristic is rejected.

Thinking Spatially:

* Space: The physical gap or interval between two objects.

* Flow: The movement of people, goods, or information between places.

* Distance: The extent of space between two points.

* Absolute Distance: Measured in standard units (e.g., miles, kilometers).

* Relative Distance: Measured in terms of time, cost, or social connectedness.

* Accessibility: The ease with which one place can be reached from another.

* Connectivity: The relationships among people and objects across the barrier of geographic space.
