Heimler- 1.4 Spatial Concepts
Spatial Concepts in AP Human Geography
Introduction
Spatial concepts are crucial in AP Human Geography.
Spatial refers to the arrangement of phenomena in space.
Geographers analyze spatial concepts to understand how things are organized.
Absolute and Relative Location
Absolute Location
Defines a precise geographical location on Earth's surface.
Uses latitude and longitude to determine exact coordinates.
Latitude: Horizontal lines running parallel to the equator.
Longitude: Vertical lines running through the Prime Meridian (Greenwich, England).
Example: The National Quilt Museum in Paducah, Kentucky is located at and
Relative Location
Describes a location in reference to another, measured in time or space.
Example: The relative location of the National Quilt Museum from Atlanta is a six-hour drive.
Walking from Atlanta to the National Quilt Museum would take six days.
Space and Place
Space
A theoretical concept describing the geometric surface of the Earth.
It is undifferentiated and lacks defining features.
Place
Describes how humans modify a space to reflect their identity and culture.
Examples: Classrooms decorated differently by teachers, reflecting their personalities.
Cultures and populations also create unique places.
Flow
Describes the patterns of connection and movement between two places.
Focuses on how people move between connected locations, not just the connection itself.
Example: At Disney World's Magic Kingdom, flow involves understanding how people move between different lands.
Geographers study the patterns of cars, boats, or people traveling between connected places.
Distance Decay
States that the further apart two things are, the less connected they will be.
Greater distance reduces connection and interaction.
Transportation and communication technologies (railroads, cars, planes, telegraph, telephone, internet) have reduced distance decay.
Time Space Compression
Describes the decreased distance between two places, measured by time or cost to travel.
Example: Traveling from Georgia to Italy took months in 1759 but only hours in 2008.
The geographical distance remains the same, but the time and cost of travel have decreased.
This concept is crucial for understanding globalization and increased connectivity.
Patterns
Geographers describe and analyze how phenomena are arranged on the landscape.
Types of patterns:
Random: No discernible pattern (e.g., pet owners in a region).
Clustered: Phenomena are tightly packed together (e.g., gas stations in populated areas).
Dispersed: Phenomena are spread out (e.g., gas stations in rural areas).
Linear: Phenomena occur in a straight line (e.g., houses along a road, towns along a railroad).
Circular: Phenomena are arranged around a central point (e.g., houses around a communal space).
Geometric: Phenomena appear in a regular, orderly fashion (e.g., farm plots in the Midwest United States).
