Canadian Physical Regions Appalachian: An extension of the Appalachian mountains Varied landscape of rolling hills, valleys, small mountains, highlands, and costal fjords Why are the mountains in this region smaller? Sedimentary rocks were deposited here as a result of glacial retreat. Rock layers covered vegetation and over time created large coal deposits Igneous rock is present as a result of ancient volcanic activity. Contains deposits of coal and minerals, rich fishing resources, vast forests, and farmland, which encouraged settlement along the coast and river valleys Because of natural harbours this region has been linked to trade and shipping for hundreds of years Canadian Shield: Takes up nearly half of Canada’s land surface. Was once a volcanic mountain range Shield regions are the oldest land formations in the world Weather and glacier activity have eroded down the landscape to flat, bare rock, lakes, and wetlands Travel is difficult, and the thin soil makes it unsuitable for agriculture Most areas are thinly populated Most of the rock in this region has been changed to metamorphic rock by heat and pressure – this also created many valuable minerals, like copper, gold, lead, diamonds, platinum, and nickel One of the world’s richest areas for mining Towns set up are mainly isolated and focused on mining Arctic Region: Characterized by plains, lowlands, and mountains Largest mountain range is the Innuitian Mountains, which were formed when pressure pushed up the sedimentary rock in that area. Due to the harsh climate and remote location there has been little mineral exploration The lowlands are composed of sedimentary rock and contains oil and natural gas deposits Increased travel in this region as well as oil and gas transportation has raised environmental concerns among the Inuit, who rely on the regions wildlife for food and clothing St. Lawrence Lowlands Found between the Great Lakes, and extend along the St. Lawrence R. to Quebec City Formed mainly by retreating ice sheets that covered Canada during the Ice Age Glaciers pushed soil into the lowlands from the shield region Fertile areas of sandy soil were left behind and the melt water drained into the basins that are today the Great Lakes This makes this region ideal for agriculture – starting with the Huron First Nations and later by Europeans Orchards of apples, pears, peaches, and cherries are found in this region Home to about half of Canada’s population Access by river has made transportation of goods and materials in an out of Canada, a thriving industry Interior Plains: Stretched from the Shield to the Cordillera Formed as soils carried by rivers from the Shield were deposited Deposits formed sedimentary rock, creating mostly flat land, rolling hills and river valleys Large deposits of fossil feuls, oils and natural gas, as well as potash are found here as a result of plant and animal remains being pressed between layers of sed. Rock Grasslands dominate this region, and have made it ideal for cattle ranches and farming Areas further north are covered by parkland and forest Cordillera: Made up of a number of parallel mountain ranges, separated by plateaus, trenches and valleys Contains dormant volcanoes, glaciers, and ice fields Rocky and Coast mountains are the youngest landforms in Canada, formed when plate collision caused the earth’s crust to buckle, pushing and folding volcanic rock into mountains – plate tectonics Rich in mineral deposits or copper, gold, and coal Mining and forestry are the major industries in this region Rich fertile soils in the Fraser River Valley is used for agriculture, industry, the river was and is vital to transportation, especially before roads and railways were built
