LANDFORM REGIONS
Why did geographers create ‘landform regions’
To understand the geography of Canada better it helps to make it into smaller chunks
How is Canada’s basic structure like a tree?
Canada started with the Canadian Shield and then grew outwards from there
The Canadian Shield
This region covers almost half of Canada.
What provinces have a part of the Canadian Shield within them?
Newfoundland, Quebec, Ontario, Alberta, Saskatchewan, NWT, Nunavut
Why does the Canadian Shield have igneous rock?
It was formed by massive volcanic eruptions.
Why is does the Canadian Shield have thousands of lakes and rivers?
Glaciers scooped out huge basins, which filled with water when the glaciers melted
What are the important resources found in the Canadian Shield?
Mining, Hydroelectric, Forestry
Where does the majority of the population of the Canadian Shield live?
Most people live in the southern part around Thunder Bay, Sudbury and Saguenay
The Great Lakes –St Lawrence Lowlands
Half of this landform region is in Quebec and the other half is in Ontario.
What type of rock can be found in this region?
◦Sedimentary rock
What role did the Canadian Shield have in the formation of the GL-SLL?
As the Canadian Shield eroded, it left sedimentary rock at the bottom of ancient seas, this hardened into Sedimentary Rock and formed the GL SLL
Why does the area have so many lakes?
Huge glaciers scraped out basins, which filled with water as the glaciers melted. These basins became the Great Lakes
What is an ESCARPMENT?
A sharp change in height caused by rapid erosion of sedimentary rock
What type of rock is the Niagara Escarpment made mostly from?
Limestone
What types of industries can be found here?
Manufacturing (automobiles) Agriculture – animals, fruit, vegetables, grains
The Appalachians
How old is this region?
◦250 million years
How was this region formed?
Plate movements forced sedimentary rock to fold upwards (FOLD MOUNTAINS)
How much of Canada’s population lives in this region?
Two-thirds
What was the effect of erosion and rising oceans on the area?
This region has a jagged coastline with many natural harbors
Who were the first inhabitants of the regions?
Indigenous People including the Mi’kmaq and Beothuk
About how much of Canada’s population lives here?
1/10 One tenth
What is one of the best known crops from this region?
POTATOES
The Interior Plains
What provinces can be found here?
BC, ALBERTA, NWT, SASKATCHEWAN, MANITOBA
What does the Interior Plains look like from the sky? Why?
Long and flat No mountains or forests
How old is the region? What type of rock can be found here?
200 million years old Sedementary Rock
How was the regions oil and gas made?
Fossilized sea life was chemically changed into oil and gas
Why is the regions well suited for farming?
The ice ages left thick layers of fertile soil over the region
Why does the area look like a patchwork quilt from above?
Government surveyors divided the land into farms, this was the most organized way.
What are the two largest cities in the region?
Edmonton and Calgary
The Western Cordillera
What provinces can be found here?
Yukon NWT Alberta British Columbia
What are the three main regions here, how were they formed, and what is their age?
Rocky Mountains- Oldest
Coast Range- 65 Million years
later
Interior Plateau - Youngest part of
the region
What natural resources could be found in this area?
Coal Minerals Farming Forestry
About how much of Canada’s population can be found here?
ONE EIGHTH
Innuitians and Arctic
Why does the textbook describe the Innuitians as “like a car that has had many accidents”?
Many fold mountains formed by sedimentary rock being pushed by tectonic plates
The Innuitians are younger than the Appalachians, but older than the Rockies.
Where can the Innuitians be found?
Far north!
What Natural Resources can be found here?
Oil and gas
How have the Innuitians changed over time?
Millions of years ago the Innuitians were covered by warm tropical seas!
What is the Northwest Passage?
A sailing route across the ocean North of Canada
What name do we give the native people of the area?
The Inuit
The Arctic is made up of many islands formed from what type of rock?
Sedimentary Rock
What does the geography of the Arctic look like?
Many lslands
Very stony
Barren, very little vegetation
Frozen!
In what territory would you find the Artic?
Nunavut
