3 major geologic elements
Canadian Shield (igneous rock), platform (sedimentary rock), folded mountains (metamorphic rock)
Canadian Shield
highly resistant igneous rock. over 1 billion years old. It extends from the Northwest Territories through the Northern Prairie Provinces, Northern Ontario, Northern Quebec, and Labrador.
platform
These rocks underlay the Interior Plains of the continent (from the Northwest Territories to Texas). . They are mainly sedimentary and contain large areas of oil and natural gas.
folded mountains
Folding is caused by the movement of tectonic plates, It caused sedimentary rock to change into metamorphic rock. Appalachian, Innuition, Cordillera
Appalachian mountains
Found in Quebec and the Atlantic Provinces, they are relatively old, relatively low, well eroded, and covered with vegetation
Innuitian Mountains
Found in Northern Nunavut, these are jagged but somewhat eroded, mostly inaccessible mountains.
Cordillera
The major ranges include the Rocky Mountains and Coast Mountains. These are the youngest mountains in Canada, the highest, most jagged, and have permanently snow-capped tops
Canada has 7 physiographic regions:
- Canadian Shield
- Cordillera
- Interior Plains
- Hudson Bay Lowlands
- Arctic Archipelago
- Appalachian Uplands
- Great Lakes – St. Lawrence Lowlands
Interior Plains
This region was once covered by a large shallow inland sea where sediments eventually formed sedimentary rock.
Hudson Bay Lowlands
This region has many bogs and contains muskeg (poorly drained soil). - permafrost
Arctic Archipelago
A complex area of coastal plains, plateaus, and mountains located north of the Arctic Circle.
The northern part of this region is permanently covered in snow and ice while the southern part contains tundra.
The region is underlain by continuous permafrost
Making tree growth impossible
Appalachian Uplands
This is an area of rounded uplands and narrow river valleys. The indented coastline of the region contains many small bays and harbours.
Great Lakes – St. Lawrence Lowlands
This is the smallest physiographic region.
The landscape is generally flat with rolling hills reflecting the underlying sedimentary rock.
The soil is very fertile and well suited for agriculture
and a variety of crops
continuous permafrost
At least 80% of the ground is permanently frozen
