1 USA and CANADA Region at a Glance

2 Physical Geography of the United States
Landforms At over 3.5 million square miles, the United States is the third-largest country in the world. Glacial activity and tectonic plate movement created the many landforms of the United States. The Pacific Ranges and the Rocky Mountains mark the western region, with some elevations over 20,000 feet. The flat landscape of the Great Plains lies in the center. Going east, the geologically older, but shorter Appalachian Mountains extend to the Piedmont’s fertile plateau, then the Atlantic Coastal Plain hems the shore.

3 Major Landforms USA Vast central plain Mountains in west - Rockies
Hills and low mountains in east - Appalachians Rugged mountains and broad river valleys in Alaska Rugged, volcanic topography in Hawaii St. Lawrence Seaway: Gateway to the Atlantic from the Great Lakes

4 Physical Geography of the United States
Water Systems The many lakes, rivers, and tributaries helped encourage economic develop along their shores. The Mississippi River in the east and the Colorado River and Rio Grande in the west form two major waterways. The Continental Divide, a high ridge in the Rockies, determines the direction of river flow.

5 Fall line Higher land of eastern US drops to the lower Atlantic Coastal Plain Eastern rivers break into rapids and waterfalls Prevents ships from the Atlantic Ocean from traveling further inland Big cities were established along the fall line Philadelphia, Baltimore, Washington D.C.

6 The Great Lakes Formed when glacier basins filled with water, the Great Lakes are part of the St. Lawrence Seaway System, a series of waterways that connect to the Atlantic Ocean. Glaciers uncovered major deposits of natural resources- iron ore and coal which led to Explosive economic growth

7 St. Lawrence Seaway Links Great Lakes with Atlantic Ocean
Ships moving through locks Links Great Lakes with Atlantic Ocean Series of canals, rivers, and waterways Helped make cities like Chicago powerful trade and industrial center

8 Physical Geography of the United States
Climate, Biomes, and Resources The large size of the United States leads to many variations in climate and vegetation. The oceans moderate temperature in coastal regions, while the interior experiences more extreme conditions. Rich in natural resources such as water, timber, fish, minerals, and fossil fuels, the United States helped speed industrialization and become one of the most prosperous countries in the world.

9 Climate Regions USA Mostly temperate However…
Tropical in Hawaii and Florida Arctic in Alaska Semiarid in the great plains west of the Mississippi River Arid in the Great Basin of the southwest

11 Natural Hazards USA Hurricanes in Atlantic and Gulf regions
Earthquakes along the Pacific coasts Tornadoes and extreme heat events (drought, grass fires) in the interiors

13 Major Modifications in the Region
Erie Canal St. Lawrence Seaway Taming the Mississippi Hoover Dam Transcontinental Railroads National Highway System

14 Erie Canal

15 The Erie Canal A canal in New York
Originally ran about 363 miles from Albany, New York, on the Hudson River to Buffalo, New York, at Lake Erie. Built to create a navigable water route from New York City and the Atlantic Ocean to the Great Lakes, allowing for grains and meats from the Midwest to get to the east coast via a waterway.

21 Human Geography of the United States
History and Geography The physical environment played a significant role in the development of the United States. Native Americans, descendants of the first waves of migrations- from Asia to Alaska, occupied North America until the Europeans began immigrating in the 1500s. Spanish, French, and then British migrations.

22 After gaining independence, during the 1800s, the country nearly doubled in territory, gaining valuable land and resources. Factories were built in along the fall line in northeast Cotton- major cash crop in the south. Two major conflicts during this time period: American Revolution, Civil War

23 Historical Geography of the USA
18th century – Thirteen colonies 1803 – Louisiana purchase 1840s – Mexican cession and Texas 1840s – Gold rush 1850s to 1890s – Westward expansion 1898 – Hawaii 1945 to Present – Postwar sunbelt explosion

24 Westward Expansion New immigrants- Europe, Mexico, China that came to the US during Industrial Revolution needed land Cities needed more food Transcontinental Railroad helped with all of these things During this time people Moved from farms to cities looking for work

25 Political Geography of United States
3rd largest country by size (after Russia and Canada) 3rd largest population (after China and India) = 310,232,863 (July 2010 est.) Constitution-based federal republic; strong democratic tradition Most powerful military in the world – Nearly half of global military spending is done for the US military alone. Only 4% of GNP, though.

29 Human Geography of the United States
Population Patterns More than 315 million people live in the United States. The aging of the population will cause challenges in government and health care costs. Population is increasing in Sunbelt states as manufacturing has declined in the North and Great Lakes region—factories are closing and sending work to China and other countries (Outsourcing). . . People are moving from north to sunbelt looking for jobs. Densely populated urban areas like the megalopolis between Boston and Washington, D.C. attract residents with economic opportunity.

32 Where are the areas of population density?

33 Human Geography of the United States
Society and Culture Today With its long history of immigration, the population of the United States is one of the most diverse countries in the world. This diverse population, coupled with the core value of religious freedom, contributed to the wide range of religions practiced today. The family remains important but the role of women is changing as more women seek employment and continue to outpace men in earning college degrees. Art and music, like jazz, developed by blending the influences of the country’s vast immigrant communities. Jazz blended African American rhythms and European harmonies.

34 Human Geography of the United States
Economic Activities The free market economy in the United States helped establish its great economic power. The economy has evolved from its agricultural origins to manufacturing to the postindustrial economy of today.– services and technology have replaced farming and factories Good transportation and reliable communications networks are critical pieces that enable the economy to function. Too many mortgages were given to people who could not afford to pay them. Homes went into foreclosure, caused some banks to fail, or led to government bailouts of banks. At same time unemployment rose.

35 People and Their Environment: The United States
Managing Resources Modern life poses a threat to the abundant natural resources in the United States. Conservation efforts by citizens and from all levels of government have increased to ensure resources will continue to flourish in the future. Resource management includes understanding and respecting the balances that exist in natural ecosystems. Efforts to reverse the damage have begun but more is needed to achieve sustainable levels.

36 People and Their Environment: The United States
Human Impact Acid rain and smog are consequences of human pollution of the air and water. Water pollution speeds eutrophication, which encourages the excessive algae growth that depletes water’s oxygen and suffocates fish. Projected water shortages could turn into droughts that cause billions of dollars in crop and livestock losses.

37 People and Their Environment: The United States
Addressing the Issues The United States is continually improving its protection of the environment by using clean-air practices, searching for renewable sources of energy, and reducing waste. Federal legislation, such as the Clean Water Act and the Great Lakes Water Quality Agreement, has helped restore water quality throughout the country. The government is working to curb environmental damage by encouraging the use of renewable energy sources and offering incentives for companies to limit emissions.
