Canada S 7 Largest Landform Regions
Canada’s 7 major Landform Areas
Precambrian Shield/ Canadian shield:
Area: -4.8 million km, almost ½ of Canada, thus the largest landform region, (actually much larger because it underlies most other regions).
-Spreads across 6 provinces, 2 territories, and the U.S.
Formation: -about 600 million years old, thus “Precambrian”.
-Igneous and metamorphic rock.
Topography: -a peneplain, almost a plain 600 metres.
-has a lakescape, many lakes.
Human Activities:-an all season vacation land.
-Also called “Mineral Storehouse”: many metamorphic rocks: minerals such as gold, copper, nickel, lead, zinc and iron found in Region.
-Forestry is also an important industry.
-Sparsely populated, people live near mining and forestry centres and along transportation links which tie them to the rest of Canada.
Major Cities: -Sudbury, Timmins, North Bay, Yellowknife, and Uranium City.
Low lands
Great lakes-ST. Lawrence Lowlands:
Area:-Smallest of landform regions.
-Located around the great lakes and on the banks of St. Lawrence River.
-“Nations Heartland”; reaches further south.
Formation: - ancient seas, deposited materials that harden into limestones, sandstones, and shales; these all rest on top of Precambrian Igneous rocks.
-Glacial Lake deposited materials and glacial ice deposited ground Moraine; The St. Lawrence Lowlands were an in land sea during glacial period (Champlain Sea-Fertile top soil on sea bed).
Topography: -Niagara Escarpment formed by erosion of softer rocks around the hard dolomite rock: Niagara River flows over the escarpment at Niagara falls.
-A fairly Flat Region.
-Mounteregion hills are exposed to Igneous intrusions, the outlying softer materials have eroded away, creating these hills near montreal.
Human Activities: -Excellent soils deposited under glacial lakes or melting continental glaciers, excellent for farming.
-Flat excellent for settlement.
-Largest population of all of the Landform Regions.
