DETAILED OUTLINE
MAJOR GEOGRAPHIC QUALITIES OF THE REALM
DEFINING THE REALM
- Physiography
- physiographic provinces (physical regions)
- map
- north-south alignment of the Rocky Mountain backbone and the much lower eastern Appalachian mountains, therefore the realm is open to air movements from the south (warm) and from the north (cold) [see "Tornado Alley" below]
- vast interior plains between the mountain chains extending from the arctic ocean to the Gulf of Mexico
- Canadian Shield
- Interior lowlands
- Great Plains
- a third north-south mountain chain on the Pacific Coast
- Sierra Nevada Mountains in California
- Cascade Mountains in Washington and Oregon
- Climate Patterns
- map
- colder in the north, warmer in the south
- in Canada east of the Rocky Mountains the warmest temperatures are similar to the coldest areas of the United States.
- continentality: colder in the interior, warmer on the coasts
- orographic rainfall and the rain shadow effect
- as moist winds come from the west they rise as they hit the coastal mountains and drop much of their precipitation on the west coast (orographic rainfall)
- to the east of these mountains is a rain shadow and dry conditions in the intermontain physiographic region (eastern California, Nevada, eastern Washington and Oregon
- as the weather pattern moves to the east it rises again at the Rocky Mountains dropping its precipitation (orographic rainfall)
- to the east of the rocky mountains is another dry area (the western Great Plains)
- as the westerly winds move to the east they pick up more moisture over the interior lowlands bringing it further east
- On the map above note the dry "B" climates to the east of the west coast mountains and east of the Rocky Mountains
- On the map below note the low precipitation found in the interior west
- RESULT: an arid (western) and a humid (eastern) America [see the 20-inch isohyet in figure G-7]
Question:
- On a blank outline map label the major physiographic features of North America.
- West coast mountains
- Rocky Mountains
- Appalachian Mountains
- Great Plains
- On the map in the question above, show where you might find a RAIN SHADOW effect.
- Use the map below to describe the spatial distribution of North America's climate and precipitation. What is "continentality"?
- The central part of the US has more tornadoes than any other place on earth
- From pp. 148-149: "A large number of storms develop here on the highly active weather front between tropical gulf air to the south and polar air to the north."
- because there are no physical barriers between the Gulf of Mexico and the Arctic Ocean
Question:
- On a map of the US show the location of "Tornado Alley" and explain
- Hydrography (Surface Water)
THE UNITED STATES






Cultural Geography - US
Question:
Economic Geography - US: the Changing Geography of Economic Activity
- Major components of the spatial economy:
- Primary Sector (extractive sector; especially mining and agriculture)
- Secondary Sector (Manufacturing sector)
- Tertiary Sector (Services sector)
- Quaternary Sector (Information)
- subset of Quaternary sector: Quinary (Management)
- primary sector was dominant up to the 20th century
- secondary sector led the way in the early 20th century
- tertiary sector (services) surpassed manufacturing around mid-century
- quaternary sector now dominant
- current labor force:
- 2% in agriculture
- 15% manufacturing
- 18% services
- 65% in the quaternary sector (including 10% in the quinary)
- PRIMARY SECTOR:
- Resource Use
- mineral resources concentrated in three zones:
- Canadian Shield north of the Great Lakes: iron ore, gold, nickel, uranium, and copper
- Appalachian Highlands: coal and iron ore
- mountain ranges of the West: coal, copper, lead, zinc, molybdenum, uranium, silver, and gold
- fossil fuel energy resources (petroleum, coal, and natural gas)
- figure 3-14
- oil:
- Gulf Coast: Texas to Louisiana
- Texas-Oklahoma-Kansas
- Alaska's central north slope
- Canada: southern Alberta-Saskatchewan-Manitoba and Atlantic Ocean around Newfoundland
- natural gas
- same as oil fields
- Coal
- some of the largest reserves on Earth
- US has a "400-year supply"
- WHERE?
- Appalachia
- northern US Great Plains and southern Alberta
- southern Illinois and into Kentucky
- Agriculture
- most space-consuming economic activity
- regionalization of US agricultural production
- a modification of the Von Thunen's Model at the Macro Scale
New "Rings", innermost to outermost:
- Atlantic Fruit, Vegetable and Dairy Belt: fruit/vegetable/dairy near populated areas
- Corn Belt: corn and corn to feed to livestock
- Wheat Belt
- Grazing Region: ranching where calves are born and sent to the corn feedlots
- Forestry
- Megalopolis is the "Central City"
- SECONDARY SECTOR: Manufacturing
- Manufacturing Belt
![]()
- close to the Megalopolis national market
- close to resources
- near coal
- access to iron ore via the Great Lakes
- access to the world via the eastern ports, Great Lakes, and Erie Canal
- historical inertia
- economies of scale
- even though these
factors have changed, industries tend to stay where they are because of historical inertia
- but industries are moving to the West and South:
![]()
- transportation costs are no longer significantly lower in the old manufacturing belt
- energy costs lower in the South and Central energy producing states
- need for more highly educated work force
- noneconomic factors appear to be more important now: amenities like warm weather, recreational opportunities
- TERTIARY, QUATERNARY, AND QUINARY SECTORS: The Postindustrial Revolution
- often called "the new economy" or "the computer age", "high technology", "white-collar"
- fastest growing sector in the US
- most are "footloose", i.e. they easily, and often, move
- Different location Factors:
![]()
- "Standard of living" amenities more important:
- warm, sunny climates favored
- suburbs, or beyond, but
- close to major city
- year-round recreational activities
- quality housing
- Economic factors
- availability of start up capital
- Low risk environment
- Tax breaks
- Cooperative state and local governments
- close to major city
- close to major university
- Businesses
- Technopole
Questions:
- How does the North American realm rank compared to other realms on the common measures of economic development?
- What are primary activities, secondary activities, tertiary activities, and quaternary activities?
- What percent of the labor force of the United States works in primary activities?
- Compare von Thunen's, model of agricultural zones (see below) with the graph of "Agricultural Regions of the United States" (see textbook, figure 3-15, p. 157). Does the von Thunen model help (at least a little) to explain the spatial distribution of agricultural regions in the United States? (see textbook!!).
- Describe WHY North America's manufacturing belt arose where it did and describe the spatial changes that are occurring now.
- Discuss the "Four Spatial Economic Changes" that have occurred in North America (See Online Lecture)
- Population Distribution
- Urbanization
- Urban Structure
- Economic Activity
