Canadian Landform Regions

• The Great Lakes-St Lawrence Lowland is the largest lowland region, covering over half of Canada's land area.
• Canadian Shield is the foundation of CDA and contains minerals.
• The Canadian Shield is mostly rock and has no soil.
• The Canadian Shield is metamorphic/igneous.
• The Canadian Shield is completely covered in continental glaciers.
• The Canadian Shield carved out divots in rock that formed lakes.
• The Canadian Shield scraped soil off of the rock, depositing it south.
• The Canadian Shield's lowlands are located in the St. Lawrence & Great Lakes region.
• The Canadian Shield's sedimentary region is fertile due to glaciers depositing fertile soil.
• The Canadian Shield's interior plains are sedimentary and are covered by shallow seas in formation.
• The Canadian Shield's sedimentary region contains carbon from the sea that has been compressed into fossil fuels.
• The Canadian Shield's flat "breadbasket" is fertile because glaciers scraped the ground and revealed potash.
• The Hudson's Bay/Arctic Lowlands region of the Canadian Shield is swampy due to minerals from the shield and natural gas.
• The Canadian Shield's permafrost is a layer of soil that is frozen during winter and thaws to the underground frost line in summer.
• The Canadian Shield's active layer is the space between the frost line and the ground.
• The Western Cordillera region of the Canadian Shield is part of the Mesozoic era and is sedimentary due to the Pacific plate colliding with the CDA shield into fold mountains.
• The Canadian Shield's Appalachian Mountains are the oldest child and were formed by the European shield collision.
• The Canadian Shield's Innuitian Mountains are the middle sister and are igneous/metamorphic, first formed by the North Pacific and North American plate collision.
• The Canadian Shield's Rocky Mountains are the youngest child and were carved out by alpine glaciers.
