Transcript Canadian Landform Regions

Canada’s
Landform
Regions
Glacial Erosion
Landform Region Map
Canadian Shield
• Lake near Port
Cartier, Quebec
• Rounded hills in the
background
Canadian Shield
• Boulder field in the
Northwest Territories
• More evidence of
glaciation
Canadian Shield
• Exposed rock along
the lakeshore
• Notice the scratches
in the rock
• They were caused by
glaciers
Canadian Shield
• A boulder in the
Northwest Territories
• It was deposited here
by a retreating glacier
Canadian Shield
• Exposed rock near
Abitibi, Quebec
• The scratches are the
result of a glacier
Canadian Shield
• Canada’s oldest and largest landform.
• Forms the foundation for the rest of
Canada.
• Very thin acidic soil. Poor for agriculture.
• Shaped by erosion (glaciers and weather).
Appalachian Mountains
Appalachian Mountains
• Bald Mountain NB
• Notice the rounded
mountains
Appalachian Mountains
• Aspy Bay in Cape
Breton
Appalachian Mountains
• Cape Breton
Highlands
• The mountains have
been flattened by
erosion
Erosion: soil and rock is moved by
wind or water to a different
location.
Appalachian Mountains

•
Atlantic Canada
Rounded Mountains through erosion
Rolling Hills and Valleys
Fertile soil. Good for farming
Western Cordillera
• Mountains of the
Yukon
• Notice the jagged
peaks
• If you looks carefully,
you will also see
glaciers
Western Cordillera
• One of the large
glaciers found in the
Yukon
Western Cordillera
• A glacier-fed lake in
Jasper National Park
in Alberta
Western Cordillera
• Jasper National Park
• The valley is Ushaped because it
was carved by a
glacier, not the river
you see here
Western Cordillera
• The Coast Mountains
provide a dramatic
backdrop in this
picture of North
Vancouver, BC
Western Cordillera
• A series of parallel mountains
• Are considered young as they have not
been effected by erosion
• Valleys are good for farming as soil has
been put there through sedimentation
• Western side has huge timber where as
the eastern side has much smaller trees.
Innuitian Mountains
• The dramatic cliffs of
Ellesmere Island,
Nunavut
Innuitian Mountains
• A glacier and its melt
water on Ellesmere
Island, Nunavut
Innuitian Mountains
• Red rocks and barren
landscape on Melville
Island
• Melville Island is
divided between
Nunavut and the
Northwest Territories
Innuitian Mountains
• Due to their “young” age they have not
been worn down through erosion.
• Rugged Peaks
• Approx 2000m in height
• The area is too cold for trees to survive.
Arctic Lowlands
• Tundra in Nunavut
• Notice the flat land
and strewn rocks
Arctic Lowlands
• The flat, exposed land
of Prince Patrick
Island in the
Northwest Territories
Arctic Lowlands
• Another image of
Prince Patrick Island
in the NWT
• The flat land allows
melting water to cover
a vast area

•
South of the Innuitian Mountains
Is a region of tundra and is treeless.
Cold, dry and poorly drained soil.
Sparse vegetation
Interior Plains
• Farmland near the
Red River in Southern
Manitoba
Interior Plains
• The meandering Red
River in Southern
Manitoba
Interior Plains
• The Cypress Hills in
Southern
Saskatchewan
Interior Plains
• The Qu’Appelle
Valley in Southern
Saskatchewan
• A rare change from
the flat landscape in
this region
Interior Plains
• Cows graze in a rocky
field
• These rocks,
deposited by glaciers,
are called moraine
Interior Plains
• Located between Shield and Cordillera.
• Created by a dried up inland sea and
through erosion
• In some areas the soil is very deep (black
soil due to carbon content) and in others it
is almost desert like
• Extends to the Gulf of Mexico
Great Lakes – St. Lawrence
Lowlands
• Typical farm in
Ontario
Great Lakes – St. Lawrence
Lowlands
• The city of Toronto
from the air
• Notice the lack of hills
• Also notice the smog
Great Lakes – St. Lawrence
Lowlands
• Farmland near
Toronto
Great Lakes – St. Lawrence
Lowlands
• Southern Ontario
from the air
• Notice the flat horizon
Great Lakes – St. Lawrence
Lowlands
• Located south of the shield (southern
Ontario and Quebec)
• Good soil is a the result of flooding by the
Champlain Sea that receded
• Experienced volcanic activity a long time
ago
• Relatively flat.
Hudson Bay Lowlands
• A wetland known as a
muskeg in Northern
Manitoba
Hudson Bay Lowlands
• The watery terrain
outside Churchill,
Manitoba
Hudson Bay Lowlands
• The water-filled
landscape near Fort
Severn, Ontario
Hudson Bay Lowlands
• A forested bog
outside Gilliam,
Manitoba
Hudson Bay Lowlands

•
North of the shield
Some places rock is 2000m thick
Poor drainage and flat terrain
swamp like forests.
