Socials 10-2: The physiographic regions of Canada

Today we started with a review of the six physiographic regions and noted how a basic knowledge of the make-up of Canada will help us later to understand why certain activities occurred in some places but not others.  It will help us to see why some places developed differently than others.  Next, we did  a jigsaw activity where, in groups, we all took one region and discovered why/how it was formed and what resources can be found there as a result.  We used the computers to extend our research and then to curate our learning as a blog comment.
Please read pp. 104-107 in your text before next class.


  1. -Landscape is rolling hills, small mountains, and fejords
    -sedimentary rocks deposited when the area was forested
    -rocks became coal over time and the other minerals such as iron, zinc, and lead.
    -It has vast forests and rich fishing grounds, ports in natural harbours used for hundreds of years for shipping
    -extension of terrain starting in the South east of the USA
    -Igneous rock can be found due to ancient volcanic activity in the area
    -There is also some metamorphic rock formed by heat and pressure over time

  2. The st. Lawrence Lowlands:
    -The region was formed by retreating ice sheets, the sheets of ice pushed soils onto where the region is today.
    -As the ice sheets melted, it created lakes. when the lakes were drained to their size today the old shoreline of the larger lakes remained a bluff.
    -The region is now made up of agricultural land. Today there are many vineyards, orchards, and wineries around the region, and they provide profit for farmers

  3. The Arctic Regions
    -Pressure at the northeastern edge of the Canadian shields pushed up the sedimentary rock to form a range of fold mountains
    -It contains similar minerals to Appalachians
    -Has deposits of oil and natural gas

  4. Western Cordillera
    - Is mostly made up of a bunch of mountain ranges adjacent to each other.
    - There are large mineral deposits of copper, gold, and coal.
    - Extremely valuable and fertile soils were created from rivers.
    - Rivers eroded the rocks and mountains creating a rough and rugged landscape.

    1. - The mountains and other geophysical features of the Western Cordillera were created by plate tectonics.

  5. 1. The landscape has many dormant volcanoes, glaciers, and ice fields.
    2. Erosion from rivers and glaciers created the rugged, mountainous landscape.
    3. There are lots of rich mineral deposits.
    4. Mining and forestry are very large industries in the Cordillera region.

  6. The St. Lawrence Lowlands are 70% farm country
    The first American to visit was James Whitworth.
    The region has an abundance of water, zinc, iron ore, coal, silver, and lead.
    It's the smallest region in Canada, but its home to about half of Canada's population.
    It was formed by retreating ice. (from the ice age)
    The ice pushed soil from the Canadian Shield to the St. Lawrence Lowlands.
    As the ice melted, it formed giant lakes, larger than the Great Lakes.
    The water drained to its current size, the area where the water used to be is fertile soil.
    The crops and farms found in the St. Lawrence Lowlands consist of apples, peaches, pears, cherries, and vineyards.

  7. Made from soils deposited from rivers in the Canadian shield, formed horizontal layers of sediment that became plains.

    resources: oil, natural gas, potash, agriculture

    elevation ranges from below 1,000 feet to 4,816 feet

    The Mackenzie Lowlands is covered with bogs and swamps

  8. -Canadian Shield started as some of oldest volcanoes on planet
    -weather/glaciers wear down volcanoes to somewhat flat
    -thin layer of soil on top (bad for agriculture)
    -Very rich in minerals
    -lots of rivers for hydroelectricity

  9. Inuitian Mountains formed by pressure and sediment from the Canadian Shield.
    Lowlands formed by glacial retreat.
    Oil, gas, gold, diamonds, limestone
    Can not farm land
    Watershed drains north Manitoba, Alberta, B.C, and Territories.
    Mountains are similar to Appalachian, Lowlands similar to St. Lawrence Lowlands

  10. Interior Plains
    - Formed as soils carried by rivers from the Canadian Shield were deposited at it's edge
    - The region was seriously affected by a drought during the last century
    - Long winters and short hot summers
    - Spruce trees are about 3 metres in height and 250 years old
    - Large areas were so dry that wind blew away the soil, creating huge dust storms
    - Remains of plants and animals were pressed between sedimentary layers to form large deposits of fossil fuels and evaporites such as potash
    - Major cities such as Edmonton, Saskatoon developed on the banks of the many rivers that criss-cross the region


  11. The Arctic Region
    - the increased rate in melting sea ice has made resources more available. Like, minerals in the Innuitian mountains and oil and natural gas in the lowlands part of the arctic.

    - Indiginous people who live in the Arctic have adapted to the harsh environmental conditions and the cold weather.

    -The Inuit rely on the regions wildlife for food and clothing.

    - Pressure from Canadian Shied pushed up rock to form a range of fold mountains called the Innuitian mountains.

  12. The Canadian Shield Region was an old volcanic mountain range. It flattened out over time from weather, erosion, and glaciers. The rock is now full of minerals such as copper, gold lead, diamonds platinum and nickel, which is mined out.

  13. the Appalachian mountains were formed because of tectonic plate collision. The mountains contain elongated belts of marine sedimentary rocks, volcanic rocks and silvers of the ancient ocean floor. you can find sedimentary rocks, coal non-metallic minerals, igneous rock from ancient volcanic activity and metamorphic rock such as iron lead and zinc. they are an older mountain rang worn down by glaciers and millions of years of erosion. There are rich fishing resources, farmland and vast forests. Most communities are near the coast or in the river valleys.

  14. The Canadian Shield
    ~Glaciers have worn away the land creating a flat landscape with many lakes and rocky areas.
    ~This region's coarse soil has left the water retaining ability of the soil at a minimum level thus disallowing proper growth of trees giving the forests a sparse and malnourished appearance.
    ~Volcanic eruptions have brought diamonds to the surface of the Kimberlite region from nearly 150km below the earths surface.
    ~All the heat from tectonic movement and volcanic activity has left this region a haven for mining of precious metals such as copper, diamonds, gold, lead, and platinum.

  15. The Arctic Region
    1.) Mountains formed by sedimentary rock being pushed together
    2.) Diamond mining has recently become one of the profitable resources
    3.) Has deposits of oil and natural gas

  16. St. Lawrence Low lands facts:
    1. Formed by receading ice sheets that covered most of Canada During the Ice age.
    2.Smallest region, it has flat rolling valleys.
    3.Contains lots of minerals and metals such as.. Zinc, Iron ore, coal and silver.
    4. Fertile soil and orchards which produce apples, peaches, pears, cherries and vineyards

    Appalachian Region.
    1. Oldest mountain range in North America.
    2.The region is over 500 million years old
    3.The mountain range was worn down by glaciers over millions of years.
    4.Contains large amounts of Sedimentary rocks, Igneous rock made by volcanic activity and metamorphic rock formed by heat and pressure, which formed minerals such as Iron lead and zinc.

  17. The Interior Plains
    - Were formed as soils carried by rivers from the Canadian Shield were deposited at its edge.
    - The Interior Plains include not only flat prairie and farmland, but also rivers, lakes and forest
    - Oil, Potash and Fossil Fuel

  18. The Crodillera~ often caused by folding, faulting, and volcano activity creating an extremely complex and rough landscape.
    parallel mountain ranges
    separated by plateaus, trenches, and valleys
    includes dormant volcanoes, glaciers, and ice fields
    stretches from Alaska to Chile
    youngest mountain ranges in Canada
    formed by plate collision, rivers, and glaciers
    mineral deposits of copper, gold, and coal are common
    mining is a major industry
    sediment carried from rivers deposits and forms places like The Frazer Valley
    rivers were vital trasportation for Natives

    The Interior Planes
    stretches from Can. Shield. to Cord. Mountains
    formed as soil from rivers was deposited
    sediment created layers of rock
    millions of years ago tropical, covered in water
    flooding left plant and animal remains that got pressed into layers of sedimentary rock
    remains pressed into oil, natural gas, and potash
    1930's drought dried out soil blew away creating dust storms

  19. -These shields are hard, rigid blocks, surrounded by younger continental land forms
    -Much of the rock of the shield has been changed into metamorphic rock by heat and pressure
    -The shield was once a volcanic mountain range. Over millions of years, weathering and erosion--especially the action of glaciers--have worn the land down to landscape of flat, bare rocks, lakes, and wetlands.
    -Volcanic eruptions have brought diamonds to the surface of the Kimberlite region from nerly 150km below the earths surface.

  20. The St. Lawrence Lowlands
    - Formed mainly by the retreating ice sheets that covered most of Canada during the last ice age
    - These areas have rich agricultural land with many farms and orchards
    - This region has large quantities of zinc, iron ore, coal, silver and lead

    ~the Appalachian region

    -it is an extension of the Appalachian region
    -it has different terrain such as rolling hills, and valleys
    -it was created by glaciers and millions of years of erosion

    thanks and once again, please pardon my late-ness
