Presentation Transcript

  1. Ch. 2 Part 2- Physiographic Regions of Canada Climatic Processes, Types and Regionalism • Geophysical Heartland/Hinterland • Determinants of Human Settlement • Characteristics of Natural Regions Superior Climate & Vegetational Impacts

  2. Climatic Processes, Types and Regionalism • Climatic Processes • Climate • The average weather conditions of a region over a long period • Effects: Winds, oceans, latitude, longitude • Global Circulation Patterns

  3. Atlantic climate effects are very different from environments created by Pacific, Arctic or lacustrine and riverain influences • -quantity and quality of water available • -exchange of warmer and cooler currents • -soils and waters rich in minerals and oxygen • -both lower and higher order of species more abundant

  4. Physiographic Regions Arctic plains, plateaux and mountains (10% - Platform, Plain, Innuit.) Interior Plains (20% - inland lake deposits) Great Lakes-St. Law- rence lowlands (2% - Champlain sea deposits Hudson Bay Lowlands (muskeg wetlands) Canadian Shield (50% Paleozoic igneous) Cordillera plateaux, mountains & valleys (16% area – young & geologically active)

  5. Climatic Processes and Types

  6. Soil Types and Vegetation in Canadian Climate Zones

  7. On this Regional Map, trace the major Climate Zones of Canada On this map, situate the Capital Cities of each province & territory

  8. On this Physiographic Map, do the major Climate Zones of Canada correspond to political regions? Why not?

  9. Continuous permafrost (80% frozen) Avge. Temp >-15 0C Discontinuous permafrost (30-80% frozen) Avge. Temp -5 -15 0C Sporadic permafrost (<30% frozen) Avge. Temp -5 0C Canada’s permafrost zones impact on settlement and resource exploitation

  10. Locate the major rivers in these 5 drainage basins. How have Canada’s drainage basins impacted on settlement and resource use?

  11. Acknowledgement of Image Sources • Glacial images and landforms from The Canadian Encyclopedia, 2003. CD Edition, available from Petro-Canada outlets. • Maps: • Physiographic regions: Robert Bone. 2002.
