LANDFORM REGIONS OF CANADA
• Canada is divided into seven landform regions:
• Western Cordillera
• Interior Plains
• Canadian Shield
• Great Lakes - St.Lawrence Lowlands
• Appalachians
• Arctic and Hudson Bay Lowlands
• Innuitian Mountains

The Western Cordillera• From West to East, the Western Cordillera is
composed of three sub-regions, each one running from north to south
• The West Coast Mountains on the Pacific coast• The Interior Plateaux in the middle• The Rockies, bordering and crossing into Alberta

The West Coast Mountains• Very tall peaks
• Volcanic
• Many fiords
• In some areas the ocean is the best way to get around
• Communities are in deep valleys on the shoreline

WEST COAST MOUNTAINS
• Subduction zone
• Oceanic plate sliding under continental plate
• Prone to earthquakes
![Page 5: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/5.jpg)
WEST COAST MOUNTAINS
• Industries take advantage of the resources and landforms in the area
• Whistler attracts a significant number of tourists
![Page 6: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/6.jpg)
THE INTERIOR PLATEAUX
• A flat highland area between mountain ranges
• There are a number of well known communities located here
• The Okanagan Valley is an important fruit farming region
![Page 7: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/7.jpg)
THE ROCKIES
• Canada’s largest mountain range
• Unlike flat regions, mountains are known for fast-flowing rivers which gouge steep valleys in the landscape
![Page 8: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/8.jpg)
The Rockies are home to many alpine glaciers
• A narrow channel of ice which slides down a mountain.
• Snow accumulates at the top of the glacier/ melts at the bottom

Interior Plains
![Page 10: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/10.jpg)
The Interior Plains (Prairies)• Once the bed of a huge sea between the Canadian Shield and the
Rockies
• Mostly flat
• Composed of sedimentary rocks
• Highly suitable for farming where climate offers the right conditions
![Page 11: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/11.jpg)
The Interior Plains Economy
• Agriculture is one of the most important activities in the Interior Plains
• Mining, for both fossil fuels and potash, is also very important
![Page 12: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/12.jpg)
Canadian Shield
![Page 13: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/13.jpg)
The Canadian Shield
• Largest region in Canada• Among the oldest known rocks on the planet• Formed by volcanic activity, therefore mostly
igneous rock• Cold winters, warm summers, precipitation all
year give it a distinctive type of vegetation
![Page 14: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/14.jpg)
CANADIAN SHIELD
• Stretches from Arctic to Great Lakes, from Mackenzie delta to Atlantic
• Soils are thin - a poor choice for agriculture in most places
![Page 15: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/15.jpg)
Great Lakes - St. Lawrence Lowlands
• Most southerly and smallest landform region of Canada
• Newest landform region
• Formed by the action of glaciers scraping away and re-depositing material on the landscape
• Consists of lakes, valleys and rolling hills
![Page 16: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/16.jpg)
The Appalachians
• The oldest mountains in Canada, worn down by erosion
• Rich in various minerals
• Good farmland in some interior areas
![Page 17: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/17.jpg)
ARCTIC AND HUDSON BAY LOWLANDS
• Northernmost inhabited region in Canada
• Most activity centers around hunting or fishing
• Resource extraction is becoming very important to the regions economy
![Page 18: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/18.jpg)
Innuitian Mountains
![Page 19: LANDFORM REGIONS OF CANADA Canada is divided into seven landform regions: Western Cordillera Interior Plains Canadian Shield Great Lakes - St.Lawrence](https://reader035.vdocuments.us/reader035/viewer/2022062308/56649e875503460f94b8ab55/html5/thumbnails/19.jpg)
Innuitian Mountains• This region is located along the islands of northern Canada and features some spectacular fiords•Vegetation in this region is low and sparse, mainly grasses and flowers or lichen and moss•Glaciers are still common in the highest parts of this region and they cover parts of several northern islands
