1. Physiographic Regions of the North
By: Joon, Atcha, and Drew

2. The Physiographic Regions of the North
There are 5 Physiographic Regions in the Canadian North.
Innuitians
Arctic Lowlands
Canadian Shield
Pacific Cordillera
Interior Plains

3. The Innuitians Older than the Western Cordillera’s Mountains.
Younger than the Shield’s Mountains.
Formed by folding
Mainly made of sedimentary rock (there is some igneous and metamorphic rock)

4. The Innuitians (continued)
Mountain tops are not as jagged as the Rockies, but sharper than the shield.
Features caused by erosion.
Due to climate there is limited activity and human uses.

5. Arctic Lowlands Made up of the islands in the far north
Mainly sedimentary rock.
Ground remains frozen all year
Poor for farming
Gently rolling landscape

6. Arctic Lowlands (continued)
Sedimentary rock contains lignite (coal).
Also contains oil and natural gas deposits.
Used for mining.
Bedrock underneath soils are formed from sediments from the Shield.

7. Interior Plains Mainly Sedimentary rocks Digging for oil/ mining
Glaciations (rolling hills)
Wet climate soils
Infertile soils from leaching (in the North)
Minerals washed away by precipitation
Boreal and Taiga forests
Coniferous and some deciduous trees
Spruce, pines, cedar, hemlock

8. Western Cordillera Rocky mountains Youngest mountain range
Tall and rugged
Sedimentary rock
Rock was folded and faulted upwards
Lakes (lorains)were formed by melted glaciers
Complex soils in mountain ranges
Many different varieties of soil types
Cordilleran Vegetation
Coniferous forests
Meadows, flowers shrubs
High altitudes - rocks, snow, ice - no vegetation
Copper, silver mines

9. Canadian Shield Rock Type: Igneous Metamorphic Formed by:
Molting/ Volcanism
Topography + Soils:
Valuable minerals (e g. lead, gold)
Human uses:
Recreation (Canoeing)
Hydroelectricity
Mining

10. Canadian Shield (continued)
Characteristics:
The oldest rock in Canada
Formed lots of lakes and has disordered lands
Infertile to farm
Covered by a thin layer of soil, and the bedrock is visible in many places
