AP Human Geography Unit 1 Vocabulary Notes

Unit 1: Thinking Geographically- Different types of maps and what they tell you. How geographers collect and use data. Spatial relationships and patterns. Data analysis at different scales (for example, global, national, local)

**Human Geography**

The study of the interrelationships between people, place, and environment, and how these vary spatially and temporally across and between locations

**Scale**

Generally, the relationship between the portion of Earth being studied and the Earth as a whole

**Place**

A specific point on Earth distinguished by a particular characteristic

**Region**

An area distinguished by a unique combination of trends or features

**Vernacular Region**

A place that people believe exists as part of their cultural identity

**GPS**

This system uses data from satellites to pinpoint a location on earth and help people find their way to a destination

**GIS**

A computer system for capturing, storing, checking, and displaying data related to positions on Earth's surface. It may show many different kinds of data on one map, such as streets, buildings, or vegetation

**Diffusion**

The spread of a feature or trend from one place to another over time

**Sustainability**

The use of Earth’s renewable and nonrenewable natural resources in ways that do not constrain resource use in the future

**Physical Systems**

The processes shaping the earth's climate; soils; distributions of plants and animals; landforms, including caves and glacial landscapes; and water, including rivers, lakes, and aquifers

**Distribution Features**

Patterns in data or features, spread over a designated geographic area

**Geospatial Data**

Information that describes objects, events or other features with a location on or near the surface of the earth

**Quantitative Data**

Any pieces of information that can be displayed using numbers, such as populations, distances, prices, and other measurements

**Absolute Location**

A place's absolute location is its exact place on Earth, often given in terms of latitude and longitude

**Relative location**

A description of how a place is related to other places

**Agricultural Density**

The number of farmers per unit of farmland

**Arithmetic Density**

The total number of people divided by the total land area. This is what most people think of as density; how many people per area of land

**Cartography**

The science of map-making

**Projection**

The scientific method of transferring locations on Earth's surface to a flat map

**Choropleth Map**

A map that uses shading to show a pattern of a variable (the darker the shading, the higher the concentration of the variable)

**Mercator Map**

A map projection that fairly accurately shows shape and direction, but distorts distance and size of land masses

**Gall-Peters Map**

A rectangular, equal-area map projection. The map shows the correct sizes of countries, but it also distorts their shape

**Robinson Map**

A map projection showing the poles as lines rather than points and more accurately portraying high latitude lands and water to land ratio

**Dymaxion /** **Fuller Map**

A map only intended for representations of the entire globe. When presented as a flat map, the land masses are unbroken. The flat map is heavily interrupted in order to preserve shapes and sizes

**Goode Homolosine Map**

It shows the continents proportionally sized to each other, however its use of distances, directions, and angles are not accurately shown because of distortion

**AuthaGraph Map**

It is considered the most accurate projection for its way of showing relative areas of landmasses and oceans with very little distortion of shapes

**Thematic Map**

A map that shows the spatial distribution of one or more specific data themes for selected geographic areas (Ex: Weather maps, population density maps, geology maps)

**Isoline Map**

A map type that has lines drawn on it connecting data points of the same value

**Dot Distribution (Density) Map**

A type of thematic map that uses a point symbol to visualize the geographic distribution of a large number of related phenomena

**General Reference Map**

A map that focuses on the location and names of features, like a political map, road map, or topographic map

**Cartogram Map**

A map that distorts the shape of geographic region so that the area directly shows a specific data variable

**Graduated / Proportional Symbol Map**

A type of thematic map with symbols that change in size according to the value of the attribute they represent.

**Contagious Diffusion**

The rapid, widespread diffusion of a characteristic throughout the population

**Core-periphery**

Central, wealthy, technologically advanced countries vs. less-developed, poor, and dependant countries

**Cultural Ecology**

The geographic study of human-environment relationships

**Cultural Landscape**

Forms superimposed on the physical environment by humans Cultural attributes of an area often used to describe a place (Ex: buildings, theaters, places of worship)

**Natural Landscape**

The physical landscape or environment that exists before it is acted upon by human activities

**Distance Decay**

The theory that states that as the distance between two places increases, the interaction between those two places decreases

**Environmental Determinism**

The theory that the physical environment controls human growth, development, and activities

**Environmental Possibilism**

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

**Formal Region**

An area within which everyone shares in a common one or more distinctive characteristics

**Function Region**

An area organized around a node or central point

**Expansion Diffusion**

The spread of a feature from one place to another in a snowballing process

**Stimulus Diffusion**

The spread of an underlying principle, even though a characteristic itself apparently fails to diffuse

**Globalization**

A force or process that involves the entire world and results in making something worldwide in scope

**Hearth**

The place from which an innovation originates

**Hierarchical Diffusion**

The spread of an idea from persons or nodes of authority to other persons or places

**International Date Line**

A line following the 180 degree latitude that runs between the South and North Poles and serves as the boundary between one calendar day and the next

**Latitude**

The numbering system used to indicate the location of parallels drawn on a globe and measuring distance north and south of the equator

**Longitude**

The set of curving imaginary lines that run North-South, coming together at the poles. They measure distance (degrees), east or west of the Prime Meridian

**Prime Meridian**

A line of 0° longitude that is the starting point for measuring distance both east and west around Earth

**Equator**

A line that runs through the middle of the Earth horizontally, separating the Earth into North and South
