Physical Geography
Section 1
Landforms and Resources
Landscape Influenced Development
 The U.S. and Canada
  occupy 4/5 of the continent
  of North America;
 Anglo America: U.S. and
  Canada are both former
  British colonies; therefore,
  most people speak English.
 U.S. and Canada have
  strong political and
  economic ties with one
      Vast Land and Abundant

 Canada is the 2nd largest country in land mass
  and the U.S. is third.
 1/8 of the land surface on earth.
 Rich in natural resources: fertile soils, large
  supply of water, forests, and large deposits of a
  variety of minerals.
 The amount of resources have attracted
  immigrants from around the world and helped
  both to become global economic powers.
             Varied Landforms
 U.S. and Canada have all the major types of landforms
 They share mountain chains in both the east and the
  west, and they also share interior plains.
   Eastern Lowlands and Interior

 The Eastern Lowlands are flat, coastal plains that run
  along the Atlantic Ocean and the Gulf of Mexico.
 The Interior Lowlands includes a terrain of lowlands,
  rolling hills, lakes and rivers, and some of the world’s
  most fertile soils.
     Interior Plains – extend from Appalachian to Missouri
     Great Plains – extend from Missouri River to Rocky
     Canadian Shield – vast, flat area around Hudson Bay
Canadian Shield   Great Plains

 West of the coastal plain
 Green and Catskill Mountains
 Blue Ridge and the Great Smoky
 Appalachian Mountains – one of
  the two major mountain chains
  in the eastern United States and
  Canada, extending 1,600 miles
  from Newfoundland south to
    Run North to South
    More than 400 million years old
   The Western Mountains, Plateaus, and

 Rocky Mountains – run
  3,000 miles from Alaska to
  New Mexico
    80 million years old
 Continental Divide – the line
  of the highest points along the
    Separates rivers that flow
     eastward from those that
     flow westward
 Earthquakes are frequent in
  this area
 Highest Peak in North America
  – Mt. McKinley in Alaska
      The Appalachian Mountains and the
              Rocky Mountains
 The Appalachian are 400 million years old
    They have been eroded by the wind and rain
    The top of the mountains are more rounded because of the
 The Rocky Mountains are only 80 million years old
    They have not been eroded by the wind and rain as much
    The top of the mountains are more pointed because of the lack
     of time and erosion
                   The Islands
 Canada’s Islands are the northern islands: Ellesmere,
  Victoria and Baffin
 The U.S.’s Islands are the Aleutians, which are in
  Alaska, and the Hawaiian Islands
Oceans and Waterways
 Three oceans: Atlantic, Arctic, and
 Both Canada and the U.S. have
  large rivers and lakes
    Provide transportation,
     hydroelectric power, fisheries,
     irrigation, and freshwater
 Great Lakes: Huron, Ontario,
  Michigan, Eerie, and Superior
 Mississippi-Missouri-Ohio
  River System: North America’s
  longest and busiest inland
 Mackenzie River: longest river
  in Canada that crosses over the
  Northwest Terrritories
Land, Forests, Minerals, Fossil Fuels

  Fertile Soil – helps to make North America the lead food
  Large forests provide lumber and other products
  Canadian Shield – iron ore, copper, nickel, uranium, and
  Appalachian Mountains and Great Plains – Coal
  Gulf of Mexico – oil, natural gas

Climate and Vegetation
                    Climate Similarities

 The U.S. has more climate zones
  than Canada
 Arctic coast is tundra with some
  permafrost – permanently frozen
 Rockies and Pacific ranges are
  highland: colder with little to no
 North central, northeast U.S., and
  southern Canada are humid
 The Pacific Coast of North America
  is a marine west coast climate
               Differences in Climate
 The U.S. has milder climates because most of the states are
  located south of the 40 degrees N latitude
    The Southern states and central and southern California
 The U.S. has parts of the country that are a dry climate
    The Great Plains and the Southwest
 The U.S. also has tropical climates
    The islands of Hawaii and South Florida
       The everglades – swampland (tall grasses and
        scattered trees) covering 4,000 square miles, locate in
Effects of Weather

 Tornado Alley – located in the
  Great Plains – Warm air clashes
  with cold air from Canada which
  creates strong thunderstorms,
  tornadoes, and blizzards
 Hurricanes in the Gulf and
  Atlantic in the summer and fall
 Heavy rains cause flooding along
  the Mississippi
 Heat and a lack of rain can cause
  droughts, dust storms, and

Human-Environment Interaction
                        Building Cities

 Where a city is built and how
  it grows depends a great deal
  on physical setting
 Factors that can affect the
  suitability of a site are
  landscape, climate, weather,
  and the availability of natural
 Water is a major factor in
  how a city is built and
                   Montreal, Quebec

 Canada’s second largest city
 Major Port
    Located on a large island
     where the St. Lawrence
     and Ottawa rivers meet
 The French built a
  permanent settlement in
 Severe winters – large areas
  developed underground
  including a network of shops
  and restaurants
                 Los Angeles, California

 Thousands were attracted
  to the mild climate and
  the ocean in the early
 Became the second
  largest city in the U.S. in
    Rapid growth brought
     pollution, inadequate
     water supplies, and
     development on
    Trails and Inland Waterways
 When the Europeans colonized, they started on the
  coast and worked their way in
    Oregon and Sante Fe Trails
    Built canals along the Mississippi and Ohio
    Erie Canal – first navigable waterway between
     the Atlantic and the Great Lakes
 St. Lawrence Seaway – deepwater ship route
  built by U.S. and Canada
    Gated off sections called locks raise and lower
     the water and the ships
    Large ocean vessels can get to industrial and
     agricultural areas
    Promotes international trade
Transcontinental Railroads and the
    National Highway Systems

 Transcontinental – from the Atlantic coast to the
  Pacific coast
 First continental railroad in the U.S. – 1860; first
  one in Canada – 1885
 Railroads move goods and people; promote
  economic development and national unity
 Automobiles influenced the National Highway
 The U.S. has 4 million miles of roads while Canada
  has 560,000
