1. Physical Regions of Canada
How can Canada be divided into physical regions?

3. Appalachian Region Southeastern USA to Maritimes
Varied landscape of rolling hills, valleys, small mountains, highlands and coastal fjords
What is left of an older mountain range worn down by glaciers and millions of years of erosion
Sedimentary rock
Igneous rock
Metamorphic rock

4. The Rock Cycle

5. Canadian Shield Region
½ of Canada’s land surface
Hardest rigid blocks, surrounded by younger continental landforms
Once volcanic mountain range
2 billion years old
Sparcely populated, little soil fertility
Full of valuable minerals: gold, nickel, platinum, diamonds etc.

6. Arctic Region
Untapped mineral reserves

7. St. Lawrence Lowlands Between Lake Huron, Erie and Ontario
Glacial melt created great lake and fertile soil surrounding St. Lawrence
Niagara Falls – created by glacier activity
Millions of years ago.

8. Interior Plains Stretched from Cordillera mountians to Canadian shield
Mostly flat land rolling hills and river valleys
Millions of years ago was tropical climate – over time remains pressed between sedimentary layers to form large deposits of fossil fuels such as oil and natural gas and evaorites such as potash
Evaporite – type of sedimentary deposit resulting from the evaporation of seawater

9. Cordillera Parallel mountain ranges Rocky and Coastal mountains
Includes dormant volcanoes, glaciers, ice fields
Rocky and Coastal mountains
Formed by plate collision caused the earth’s crust to buckle, pushing and folding volcanic rock into mountains.
Plate movement called plate tectonics

10. Climates of Canada
Climate - temperatures, humidity, rainfall, and atmospheric conditions of a region over a long period of time
Continental climate – climate of continents interior
Maritime climate – a coastal climate
Conditions that affect Canada’s regions (old p.104, new p.25)
Latitude
Altitude
Distance from the sea
Wind direction
Ocean direction
Prince Rupert, Edmonton, and St.John’s are all app. same latitude, yet have different climates. What are the main reason the climate of each city is different from the other two?

11. Climographs (old p.105, new p.26) precipitation and temperature
Precipitation - Rainfall, snow, hail and fog – varies by region
Climographs – show average monthly temp. with line graph and monthly precipitation with bar graph

12. Climate Change
Past 200 years world’s become more industrialized and burns massive amounts of fossil fuels (coal, oil, natural gas) - trapped green house gases in atmosphere
Greenhouse effect – change of weather patterns
List 3 impacts climate change has had on your community. In what ways has if affected you and your family? (socially, economicaly, politically?)
