Great Lakes St. Lawrence Lowland
Canadian Shield
Interior Plains
Intermountain Region
Arctic Plains
Appalachian Region
Coastal Plains
Western Cordillera
4. Great LakesSt. Lawrence Lowland
Smallest region in Canada
This region have tons of escarpments (Niagara
Escarpment) most known escarpment in this region.
This region is bounded by Canadian shield, to the
north and Appalachian Mountain, to the south.
The Great Lakes section has rolling landscapes
created mainly by glaciation(being covered by
glaciers or ice sheets)
The St. Lawrence section consist of flat plains on
either side of the river.
5. Climate
Humid
continental climate
The Great Lakes tend to cool the
temperature during summer, by storing
heat
It also warms the surrounding areas in
Winter
Winter: cool- cold
Summer: warm- hot
8. Canadian Shield
2
billion years old
Consist of great volcanic mountains
Consist a platform of rocks
Consist of chaotic patterns of lakes, rivers,
swamps and muskeg.
The geographic foundation of Canada
9. Climate
If you travel north the winters become long
and colder
Summers are becoming shorter and cooler
10. Vegetation
Boreal
forest covers most of Canadian
Shield(has sandy soil)
spruce
pine
fir
poplar
white birch
These trees are suited for pulp and paper
industry.
15. Environmental Concerns
Use
of auto mobiles
Disposing of waste into landfills
Lumber harvesting
Erosion
Farm pollutants seeping into the ground
and operating off into the river and lake
programs
16. Intermountain Region
Thinly
populated area of high plateaus
and isolated mountains
Consist of interior plateau valley of BC
and Yukon.
Their streams and river never reach the
sea, they flow into brackish(somewhat salty lakes)
17. Climate
Its
climate is affected by its location and
by its elevation
Winters can be cool and wet or hot
depending on the region
Winters are short and warm with very little
precipitation
The northern portions of the region lacks
precipitation.(climates moderate with moist winters and hot
dry summers)
18. Vegetation
Sparse
grassland to plants that can
survive in semi desert or desert conditions
Higher areas are covered in thin pine
forest.
20. Arctic Plains
Combination
of lowlands and mountains.
Arctic near the ocean is very flat.
Mountains at far north are covered by
glaciers.
Arctic is a desert.
24. Appalachian Region
Made up of many different mountain
ranges(old mountains formed 300 million years ago)
Erosions made these mountains into rolling
mountains and hills.
Have fertile plateaus and river valleys.
Coal, Oil and Gas can be found in
sedimentary rocks.
The Appalachian Regions rivers can provide
transportations.
25. Climate
It’s climate is affected by two ocean currents:
The Labrador Current
- Brings cold water south from the Arctic and
causes freezing during the winter months
The Gulf’s Stream
- Bring warm water north from the Caribbean
and along the coast of North America
26. Vegetation
It’s
heavily forested with
coniferous(evergreens) and deciduous(trees
that shed leaves annually)
They have poor mountain soil
32. Western Cordillera
Consist
of range after range of mountains
separated by plateaus and valleys
The Rocky Mountains are the most easterly
range of mountains in this region
Comprised of new mountains
(twice as high as Appalachian mountains)
33. Climate
Maritime
climate(strongly influenced by the
closeness of a large body of water).
Some parts of Western Cordillera are the
wettest regions on earth
Winters are above freezing and summers are
cooler than in the interior of the continent.
The west coast is moist and mild.
34. Vegetation
On the moist, windward slopes, evergreens,
such as Douglas fir, western hemlock and
western red cedar grow to tremendous size
on the lowest slopes
The giant sequoia(The largest tree in the
world)
On top of the mountains there are small trees.
On the leeward slopes, grasses and cactuses
grow in the dry valleys.
35. Environmental Concerns
Construction
and development of land is
causing habitat destruction in the Eco
zone.
Industrialization and urbanization is
causing water shortages.
Forest fire happens every year.
