Title: Canada
1Canadas Physical Geography
- Canadas physical geography is as diverse as any
country in the world! - There are 3 major landform types found in Canada.
They are - The SHIELD
- The LOWLANDS
- The HIGHLANDS
2The Canadian Shield
- Lakes, rocks, and forests
3Where is the Canadian Shield?
- The Shield is Canadas largest landform region
by far.
4The Canadian Shield
- Formed 4 billion years ago by volcanism magma
cooled and became IGNEOUS rock (granite) - While the magma cooled, metallic minerals seeped
into cracks these metals are part of Canadas
mining industry (nickel, gold, silver)
5The Canadian Shield
- The Shield has been eroding for billions of years
by wind, rain, rivers, glaciers and other
weathering processes - Today, the Shield is mainly flat and rocky with
lakes filling holes carved out by glaciers
6The Canadian Shield
- glaciers scraped away much of the soil soils are
thin and the granite is exposed as a result,
farming does not occur on the Shield. - The Shield is covered by coniferous forests
(pine, spruce, cedar) which can survive the cold,
harsh climate and thin soils.
7The Canadian Shield
- Major industries
- Mining towns (Sudbury nickel)
- Forestry towns (Kirkland Lake)
- Pulp and paper towns (Ottawa-Hull)
8The Canadian Shield
- Due to the wide network of lakes and rivers on
the Shield, another major industry is the
production of hydroelectric power - Rivers are dammed to produce 60 of Canadas
electricity
9The Lowlands
- Sedimentary rocks, thick soils, and cities
10The Lowland Regions
- Made up of 2 major regions
- Great Lakes/St. Lawrence lowlands
- Interior plains (the prairies)
- Plus the Hudson Bay/ Arctic Lowlands
11Where are the Lowlands?
Hudson Bay Lowlands
Interior Plains
Great Lakes- St. Lawrence Lowlands
12The Lowland Regions
- The erosion of the Canadian Shield and the
Highlands created layers of sediment that settled
in shallow tropical seas over millions of years,
sedimentary rock formed. - Within the layers of sediment, dead organisms
(plants and animals) became trapped and fossilized
13The Lowlands Interior Plains
- Characterized by generally flat but rolling
landscape - Thick, fertile soils covered by grassland
- Fossilized remains of ancient coral reefs,
trapped in the sedimentary rock, transformed over
millions of years into oil and gas deposits
14The Lowlands Interior Plains
- Important to Canada because of
- Agriculture
- Wheat
- Cattle
- Oil and gas
15The Lowlands Interior Plains
- Even though the land is relatively flat, there
are a series of escarpments created by the
differential erosion of glaciers - Escarpments form when a harder rock layer that
overlays a softer layer resists erosion
16The Lowlands Great Lakes/St Lawrence Lowlands
- Gently rolling hills covered with mixed forest
(deciduous and coniferous trees) - Thick, fertile soils used for farming (especially
tender fruit crops on the Niagara Escarpment) - Dominated by URBANIZATION
- Location of Great Lakes and St. Lawrence River
Basin
17The Lowlands Great Lakes/St Lawrence Lowlands
- The Great Lakes are located in basins that were
gouged out by glaciers when the glaciers melted,
they left huge lakes (even bigger than they are
today!)
18The Lowlands Great Lakes/St Lawrence Lowlands
- This region is the most southerly region in
Canada - It is well suited to farming because of its
excellent soils and warm climate
19The Lowlands Great Lakes/St Lawrence Lowlands
- The Niagara Escarpment
- Formed by differential erosion
- World famous for grapes that make wine other
tender fruit crops include peaches and cherries - Lake Ontario keeps the vineyards cool in the
summer and warmer in the winter - Niagara Falls produces a significant amount of
hydroelectric power
20The Lowlands Great Lakes/St Lawrence Lowlands
Toronto
- 50 of Canadas population lives in the Great
Lakes/St Lawrence lowlands even though its only
1.4 of Canadas land area - The region is dominated by CITIES including
Canadas 2 largest cities (Toronto Montreal) - The region is Canadas manufacturing centre 70
of Canadas manufacturing industries are located
here
Montreal
21The Lowlands Hudson Bay/ Arctic Lowlands
- This region is located around the southwestern
shore of Hudson Bay - It is a flat, low area covered by swampy forest
- The harsh climate does not permit farming a lot
of the soil is permafrost (permanently frozen)
22The Highlands
The Appalachians
The Innuitians
The Rockies
- Mountains, glaciers, and more mountains!
23Where are the Highlands located?
- EAST of the Shield and Lowlands Appalachians
- WEST of the Shield and Lowlands Western
Cordillera - NORTH of the Shield and Lowlands Innuitians
24The Highlands-- Appalachians
- North Americas oldest mountain range 300
million years old! - Sedimentary rock was uplifted and folded when the
North American plate collided with Europe and
northern Africa - Millions of years of EROSION have made these
mountains more like rounded, rolling hills
25The Highlands-- Appalachians
- Sedimentary rocks are surrounded by igneous and
metamorphic rocks (formed by volcanism) - Sedimentary rock layers are rich in layers of
coal coal mining is a major industry in the
Appalachians - The region is home to drowned coastlines
excellent harbours for large cities
26The Highlands-- Innuitians
- Canadas huge mountains in the Arctic formed 150
million years ago - Contain some igneous and metamorphic rock, but
are mostly composed of folded SEDIMENTARY rock - Barren, treeless mountains covered in snow and
icy glaciers - Mining doesnt occur due to the remote location
in Canadas high Arctic
27The Highlands Western Cordillera
- Canadas youngest mountains approximately 100
million years old - Made up of 3 distinct mountain ranges Coast
Mountains, Columbia Mountains, and Rocky
Mountains - Formed by the collision of the Pacific plate and
the North American plate - The folding, faulting, and volcanic activity
caused by the collision resulted in the ranges of
the Western Cordillera
28The Highlands Western Cordillera
- The north-south direction of the Western
Cordillera makes transportation from the east to
the west difficult only a few mountain passes
allow railways and highways through the range - The growth of the major cities in the region
(Vancouver Victoria) are limited by the
presence of the mountains - Most of the Western Cordillera is lightly
populated because its so mountainous
29The Highlands Western Cordillera
- Outside of Vancouver Victoria, most people live
in farming and mining towns in river valleys - Mountain towns like Banff, Lake Louise, or Jasper
have small populations but are very important
tourist destinations - Tourists come to see the spectacular scenery and
the only remaining glaciers south of the Arctic.
30Canadas Physiography
- Canadas diversity is found across the 3 landform
types - Canadian Shield
- Lowlands
- Highlands
- WHAT A COUNTRY!
