  1. Defining a Region: Connections, Relationships, & Location

  2. GEOGRAPHIC REGIONS • Represent great clusters of humankind or physical characteristics • Change over time • Do not have definite borders • May differ based on point of view • Vary in size • Separated from other regions by transition zones.

  3. TRANSITION ZONES • Location: Edge of a region • An area of spatial change where peripheries of two adjacent regions join • Marked by a gradual shift (rather than a sharp break) in the characteristics that distinguish neighboring regions • Area of mixed characteristics; possible tension (cultural groups)

  4. GEOGRAPHIC REGIONS What defines a region? Regions are based on Spatial Criteria • Location, location, location • Common Characteristics • Physical (natural) • Landforms, Climate, Vegetation, Biomes… • Human (cultural) • Language, Religion, Ethnicity, Population, Disease…

  5. Dominated by one political power: North America: U.S. Middle America: Mexico South America: Brazil Russian Realm: Russia East Asia: China South Asia: India Southeast Asia: Indonesia Australian Realm: Australia No dominant State Europe Sub-Saharan Africa North Africa / Southwest Asia Oceania (Pacific Realm) Sub-classification of Regions

  6. SUB-REGIONS • Classification of Regions based upon physical features or humancharacteristics or both. • All regions can be divided into sub-regions • Ex: United States’ Location: North American Region. • U.S. Sub-regions may include: • Northeast, Midwest, South, North … or… • Metropolitan and suburban areas …or… • Physical regions (Rocky Mountains, the Great Lakes) • Texas example: Hill Country, Piney Woods, West Texas, The Valley, The Coast, East Texas, The Panhandle… • Region & Sub-region boundaries are based on criteria we establish.

  7. FORMAL REGION • Marked by a certain degree of homogeneity in one or more phenomena. Examples: Corn Belt Sun Belt Rust Belt Latin America Southwest Asia

  8. FUNCTIONAL REGION • A region marked by its dynamic internal structure • A spatial system focused on a central core • A region formed by a set of places and their functional integration (Ex. River systems, Highways, Railroads systems, Communication systems, etc.) • Example: • Los Angeles Metropolitan Area • Mississippi River Watershed

  9. Perceptual Region • A region that is marked by unique human ideas or perceptions. • Examples: • “The Orient” or the “Tropics” • The “South” v. the “North” • The “Middle East” v. “Southwest Asia” • “Central Texas” “Hill Country” • A region of the city or town: “Mid-Town” “Downtown”
