PHYSICAL REGION OF NORTH AMERICABy: Michael. Xiong Social Studies 9 Block D(It is recommended to play with sound on)
PHYSICAL REGIONS
The eight physical regions:
1. The Appalachian Region
2. The Coastal Plains
3. The Great Lakes and
Saint Lawrence Region
4. The Interior Plains
5. The Canadian shield
6. The Western Cordillera
7. The Intermountain Region
8. The Arctic Region
Topography:
• Gentle rolling hills from erosion
• Fertile plateaus and river valleys
• Extends for ~2400 km
• 160km ~ 480km in width
Climate:
• Icy water from Labrador current
• Warm water from Caribbean gulf
• Freezing winter in northern area
Vegetations:
• Mixed with coniferous and deciduous
• Able to survive poor mountain soil
•Vegetations in river valleys with rich soil
Economic Activity
• Large scale logging
• Coal mining and gas mining
• Farming crops (corn, squash, tobaccos… etc.)
Environmental concerns
• Mining clears forests areas
• Over logging
• Destructions of landscapes
THE APPALACHIAN REGION
Topography:
• Elevation: 200~30 meters above sea level
• Flat or gentle rolling
• Numerous swamps and marshes
• Sediments formed Mississippi Delta
Climate:
• North have humid summer & snowy winter
• South have relatively warm winter
• South have hurricane in summer & winter
Vegetations:
• Plants adapt to sandy soil
• Lush forest developed (Mexico)
• Originally pine forest
Economic Activity
• Tourism and sightseeing
• Fishing at coast
• Forestry (paper making, logging, lumbering… etc.)
Environmental concerns
• Expansion of cities
• Air pollution from urban sprawl
• Building of dams disrupting rivers
COASTAL PLAINS
Topography:
• Smallest region in Canada
• Rolling landscape from glaciations
• River valleys, flat plains, hills and escarpment
• Contains the three great lakes. (Ontario, Erie, Huron.)
Climate:
• Continental climate
• With little influence of sea & large temperature range
• Humid due to lakes
• Lakes cools down temp during summer
• Lakes warms up temp during winter
• Temp varies from stored energy in lake
Vegetations:
• Once filled with trees. (maple, oak, birch, ash … etc.)
• Fertile and moist soil provide resource for vegetations
• Once have large broad leaf forest
Economic Activity
• Lake provide transportation for trades
• Advance in automobile development
• Tourisms and sightseeing
• Steel /metal industries
Environmental concerns
• Invasive species
• Native species decreasing
• Industrial pollutions
• Water withdrawal
THE GREAT LAKES – ST. LAWRENCE LOWLAND
Topography:
• Runs between Rocky Mountains & Appalachian Mountains
• 600~1500 m from sea level
• three elevations separated by escarpments
• Northern part reaches Arctic ocean
Climate:
• Continental climate
• Little overall precipitation
• Hot summer and cold winters
• Some parts affected by tornadoes
Vegetations:
• Prairie area full of grass
• Trees around eastern Mississippi
• Trees also in river valleys
Economic Activity
• Agricultural activity. (cattle, pigs, poultry)
• Mining for gas and oil
• Farming. (wheat, barley, oats, starches… etc.)
Environmental concerns
• Over farming and grazing
• Pollutions from agricultural activity
• Disposing wastes & land fills
THE INTERIOR PLAINS
Topography:
• Mix of rocks, rivers, swamps and muskegs
• 100~500 m above sea level
• Cover more than half of Canada
• Volcanic mountains from erosion
Climate:
• Varies among areas
• North have long winter and short summer
• South have longer summer
Vegetations:
• Boreal forest
• Trees presented around south
• Northern area hard to support plants
Economic Activity
• Minerals mining (gold, lead, copper, zinc, nickel…)
• Logging boreal forest
• Tourism and sightseeing
• Hydro electricity generation
Environmental concerns
• Acidic/toxic rain
• Acidification of lakes
• Coal powered energy plant pollutions
THE CANADIAN SHIELD
Topography:
• Consists of mountains (higher than Appalachians,)
• West side rivers flow to Pacific
• East side rivers flow to Hudson Bay
Climate:
• Maritime climate affect by sea w/ high precipitation
• Wet and moist
• Mild winter w/ cooler summer
• Windward slopes more moisture
Vegetations:
• Windward parts have coniferous trees
• Leeward parts have grass & cactuses
• South have no evergreens
Economic Activity
• Forestry (large area of trees)
• Fishing (Salmon fish)
• Agriculture (course grains & oil seeds
Environmental concerns
• Oil pipe constructions
• Over harvesting timbers
• Over grazing
• Oil explorations & over mining
WESTERN CORDILLERA
Topography:
• Lies between Rocky & coastal mountains
• Rivers may flow to brackish lakes
• Contains deserts
• Contains Plateaus
Climate:
• Varies among locations
• South have dry, mild and short winter
• North have moist and long winter
Vegetations:
• Grassland areas
• Cactuses & plants adapted to deserts
• Higher areas have pine forests
Economic Activity
• Logging of pine trees
• Cattle ranching
• Mining in the mountains
Environmental concerns
• Destruction of ecosystem
• Birds endangered from human activity
• Dry air/ air pollutions
• Over logging
INTERMOUNTAIN REGION
Topography:
• Tundra area
• Mix of lowland islands & mountains
• Land near ocean is flat
• Parts covered by glaciers
Climate:
• Extreme climate due to distance from equator
• Winter lasts more than 10 months
• Little precipitation (making it a desert)
Vegetations:
• Few plants grow
• Trees can’t survive
• Shrubs and lichens manage to live
Economic Activity
• Oil/gas development
• Hidden minerals in the region
• Rich source of fishes
Environmental concerns
• Global warming and melting glaciers
• Toxic gases released from melted ice
• Changing of sea levels due to melted ice
• Destructions of ozone layer
