Presentation on theme: "Physiographic Regions of Canada. Background Canada is a land of great physical diversity Topography: earth’s surface features including vegetation, soils,"— Presentation transcript:
The Canadian Shield More than half of Canada some of the world’s oldest rocks Contain large deposits of lead, gold, nickel, and other metals
Relatively flat with rounded hills Not suited for farming because it has very thin soil
Interior Plains Rounded hills and lakes Deposits of sediment from glaciers Turned into sedimentary rock Very fertile soil
Great Lakes-St. Lawrence Lowlands Sedimentary rock Glaciers created rolling landscape, with hills and valleys St-Lawrence portion is a rift valley: created when the land between two cracks in the earth drops down
Good for agriculture because of its excellent soils and warm climate
Hudson Bay-Arctic Lowlands Hudson Bay very flat, low area covered by swampy forests Layer of sedimentary rock which rests on top of the ancient rock of the Can. Shield.
Arctic made up of a series of islands, with rolling hills Harsh climate, with ground remaining frozen almost all year
Appalachian Mountains Oldest mountain region in Canada Layers of sedimentary rock rich in minerals Erosion has reduced them to rolling hills
Innuitian Mountains Younger, so limited erosion Mostly sedimentary rock Contain minerals, but have not been exploited very much yet
Western Cordillera Ranges of mountains, separated by plateaus and valleys Geologically young Glaciers in mountains
