The Map


Landforms


Landforms

• Both are on the North American continent, which also includes Mexico and Central America.

• Together these two countries encompass every type of landform and climate classification that exists.


Appalachian Highlands and Lowlands

• Low-lying mountains from Newfoundland to Alabama• Six distinct landforms:

1. Piedmont—PA southward to GA2. Fall Line—Series of river and stream rapids that mark the edge of the

Piedmont where it descends on the coastal plain3. Blue Ridge Mountains—NC, TN, and GA (also called Great Smokies)4. Ridge and Valley province

• Folded landscape of long, parallel ridges and valleys from NY to northern AL

• Includes Hudson and Shenandoah Valleys5. Appalachian Plateau—Western portion of Appalachian Highlands6. New England

• White Mountains of NH and ME• Green Mountains of VT• Continues into Canada to form a Maritimes–Newfoundland extension


Gulf-Atlantic Coastal Plain

• Gulf of Mexico to U.S. Atlantic Coast• Location

– Cape Cod to Florida– Florida– Coastal Texas– Much of lower Mississippi Valley


Western Mountains and Plateaus

• Rocky Mountains—Northern NM northward to CO and WY

• Interior plateau– West of the Rocky Mountains – Transition between Rockies and Pacific

Coastlands


Western Plateaus

• Colorado plateau—More than a mile high in SW CO, eastern UT, northern AZ, NM

• Basin and range– West and south of the CO plateau– Much of NV and western UT, parts of southern CA and AZ

• Columbia plateau– North of basin and range– Eastern OR and WA– Snake River area of ID

• Pacific Coastlands– Sierra Nevada Mountains

• North to south in eastern CA• Eleven peaks in excess of 14,000 feet

– Cascade Mountains• North of Sierra Nevada• Central OR and WA

– Coast Ranges—Length of the Pacific Coast• Great Valley—Alluvial trough• Willamette Valley (OR)• Puget Sound Lowland (WA)


The Canadian Shield

• Shields– Piece of Earth’s crust that is very old and

geographically very stable– Probably cannot be further revised– Cultural nuclei around which mountain formation

tends to occur• Location

– Extends outward from the Hudson Bay– Includes much of Quebec & Labrador– Most of Ontario & Manitoba– Substantial part of Canadian Arctic


Interior Lowlands

• South and west of the Canadian Shield• Between North America’s backbones of east

and west• Components

– Great Plains—East of the Rocky Mountains– Great Lakes—MI, NY, and Ontario– Ozark Plateau—MI– Ouachita Mountains—AK– Black Hills

• Western SD• Peaks that exceed 7,000 feet


Climate


Climate

• Several influencing factors:– Clearly defined changes in seasonal temperatures– Prevailing wind direction is west to east.– North–south mountain ranges in the west modify air masses as they

move east.– Atmosphere takes on the more extreme heating and cooling

characteristics of land than water.• Winters are cold.• Summers are hot.

– Gulf of Mexico—Important source of moisture for the Gulf Coast and Interior Lowlands

• Characteristics:– Humid subtropics– Dry subtropics– Marine west coast – Western steppes and deserts– Humid continental – Subarctic and polar climates


Humid Subtropics

• Hot and sticky• Eastern Texas and Oklahoma east to

Florida and Virginia and sections of West Virginia

• The climate in many of these states is subject to extremes.


Dry Subtropics (Mediterranean)

• Pacific Coast• San Diego to San Francisco

– Summers relatively cool (time of drought)– Winters relatively warm

• Precipitation low, but clearly defined wet and dry seasons

• Lack of snow


Marine West Coast

• Northern CA to Alaska• Winter—Warmer due to moderating effects

of ocean• Summer—Cool• Cascade mountains produce a moderating

effect.


Western Steppes and Deserts

• Eastern OR and WA south to Colorado Plateau• East of Rocky Mountains—Corresponds roughly

to the Great Plains• Semiarid climate• Temperatures tend toward extremes• True deserts of North America concentrated in

the southwest:– Southern TX– Southern AZ– Southern CA


Humid Continental

• Northern part of United States into southern Canada

• Humidity• Winter—Cool to cold• Summer—Can be very hot• Home to America’s agricultural heartland

– Corn Belt– Dairy Belt


Subarctic and Polar

• Subarctic– Wide swath of central Canada and Alaska– Precipitation levels low—Mostly as summer rain

• Polar• Northern edges of Canada and Alaska

– Freezing conditions most of the year– Some days without sunlight


Environmental Challenges

• Continental climates have always experienced environmental extremes.

• Water issues in dry conditions cause issues.

• Northeastern and midwestern locales may experience too much water.

• Storms, especially in the southeast, may cause dramatic problems.


Water Competition in Desert


Historical Settlement

• European core has influenced the early settlement of both countries.• Core influences:

– New England—MA, RI, and CT• Originally a destination for religious freedom• Artisanal work and shipbuilding

– Southern Atlantic—VA and southward• Cultivation of subtropical crops—notably tobacco• Plantation system a major aspect of work by smaller farms

– Middle Atlantic—NY, PA, and parts of NJ and MD• English, Dutch, Scots–Irish, and Swedish influences• Mixed agricultural system• Manufacture of tools, guns, and wagons• Iron ore work in PA• Influential impact of American middle west and parts of Appalachians

– French Canada—Quebec; St. Lawrence River area• Early settlers were French; British took over in 1763.• Some farming along St. Lawrence River• French Canadian population has remained contextual; little spatial diffusion.


Historical Settlement


Western Expansion

• Historical view was that all land on the continent is to be civilized by Americans

• Expansion of United States– Louisiana Purchase—1803– East Florida—1819– West Florida—1810–1813– Texas—Annexed in 1845– Mexican Cession—1848– Oregon County—1848– Gadsden Purchase—1853


Evolution Of Canada


Population

• U.S. population growth after 1800– High birthrates (fertility

rates)– Low death rates (mortality

rates)– Immigration

• Canadian population growth– Grew mainly by natural increase between 1867 and 1900– But limited by a low fertility rate

• Population distribution– Predominantly east of the Mississippi River– Greatest concentration in northeast quadrants

• Population of Canada– Most people live 200 miles of U.S. border

Agricultural Regions


Agriculture Regions

• Corn Belt—Central Ohio to eastern Nebraska; MN to SD; Kansas

• Dairy Belt—North of the Corn Belt, stretching westward from Nova Scotia and New England to WI and MN

• Specialty Crop and Livestock Region—Southern New England to eastern Texas

• Great Wheat Belts – Winter Wheat Belt

• KS, OK, CO, and north TX– Spring Wheat Belt

• ND, SD, MT, and Saskatchewan

• Western farming


Energy

• Coal– Major energy source for industrial expansion in United States: WY, KY,

WV, and PA– Nova Scotia, New Brunswick in Canada– Easier to import from U.S. Appalachian states– More emphasis on petroleum

• Oil and gas– Both United States and Canada are major producers and consumers.– United States—Production centered in TX, LA, KS, CA, and AL– Canada—Alberta and Saskatchewan

• Water– 60% energy via hydroelectricity in Canada– 8.5% in the United States

• Nuclear– 20% source of power in United States– 12% source of power in Canada


Energy

• Iron ore– United States and Canada are major producers and consumers.– Canada—Exporter– United States—Importer

• Aluminum– Used extensively in transportation and construction– Imported from Jamaica, Suriname, Guyana, and Australia as it is

not readily available

• Canada produces other metals:– Nickel– Copper


Manufacturing

• New England– Waterways– Railroads

• South– Remote from transportation– Produced for exporting

• Coreland– Southern New England

• Textile• Leather-working• Machine tools

• Metro New York– Diversified manufacturing– Garment industry


Problems Facing Manufacturing

• Intensive foreign competition• Labor costs cheaper• More modern equipment• Difficult economic conditions• Recessions• Fluctuations• Social problems• Social conflict• Air and water pollution• Residential quality• Urban water supply


Canadian Manufacturing

• Location—St. Lawrence Seaway and Ontario– Industrial heartland– Montreal the center of industry—Akin to NYC

• Specialization elsewhere– Hydroelectric potential—Quebec– Golden Horseshoe

• Most of Canada’s steel• Great variety of other goods• Protected by tariff

• Drift westward– Alberta and western provinces gain– Similar trends to United States


Urban Dynamics

• Cities’ natural attraction for industrialism– Agglomeration economies– Multiplier effect

• Highly urbanized by beginning of 21st century• Globalization transforming cities

– Transportation• Expressways• Automobiles

• Spatial expansion• Megalopolis

– Result of congestion and sprawl– “A very large city”– More government—More demands

• Canadian Cities– More acceptance of government planning– More compact; higher densities– More emphasis on public transportation


Poverty in United States


Poverty in Canada


Poverty

• 78% of all poor live in metropolitan areas.• Effect of biases against specific ethnic groupings

– African Americans– Hispanic Americans– Native Americans– Appalachian whites

• Concentrated in central cities• Appalachia• Other areas

– Mississippi Delta– Along the Mexico border– Native American reservations in north central


Diversity

• Numerous subgroups distinguished by race, ethnic and linguistic differences– African Americans– Hispanic Americans– Asian or Pacific Islanders


Canadian Diversity

• Tension between English-speaking and French-speaking– Anglophones—Native English speakers– Francophones—Native French speakers

• Population Demographics– French-speaking

• Quebec• New Brunswick• Predominantly Roman Catholic

– English-speaking• Western provinces• Maritimes• Predominantly Protestant

• Multilingualism (other than French and English)– Toronto– Montreal– Produced by immigration and ethnic clustering


Canadian Diversity


Summary of Chapter

• The United States and Canada occupy one of the largest land masses in the world, and one with a wide array of environments.

• Both countries evolved out of a spatial integration process in which frontiers were pushed back by advancing populations. The result is a racial and cultural mosaic that enriches their contemporary geographies, while presenting challenges to governments that struggle to accommodate competing groups.

• Each country is an economic powerhouse that occupies a prominent position in the world economy.

• Progress has come with costs in terms of environmental degradation, global warming, employment insecurity among North American workers, increased reliance on foreign sources for important natural resources, and a growing fear that economic progress may not be sustainable.
