In total, the Canadian Shield covers approximately 8 million square kilometers. Because a large portion of the worlds boreal zone lies in Canada (28% or 552 million hectares), this countrys boreal forest affects the health of the environment worldwide. Climate Graph & Average Temperature Quebec. That is half of the Canadian amount. Given the prominence of the boreal forest throughout the Canadian Shield, forestry is also a prominent industry. When the Greenland section is included, the Canadian Shield is approximately circular, bounded on the northeast by the northeast edge of Greenland, with Hudson Bay in the middle.

(It also reaches into parts of the United States, in New York, Wisconsin and Minnesota.) Mountains have deep roots and float on denser mantle, much like an iceberg at sea. The region, as a whole, is composed of ancient crystalline rocks whose complex structure attests to a long history of uplift and depression, mountain building (orogeny), and erosion. Canada's topography is dominated by the Canadian Shield, an ice-scoured area of Precambrian rocks surrounding Hudson Bay and covering half the country. Learn about the most current global climate model data, the 6th Coupled Model Intercomparison Project (CMIP6). (This is the full-length entry about the Canadian Shield. The Canadian shield is covered by a thin layer of soil and forms the nucleus of the North American cratonan old and stable part of the continental crust that has survived the merging and splitting of continents and supercontinents for over 500 million years.

The southern part of the Canadian Shield gets lots of rain and snow each year. The Canadian Shield, a northern region constituting almost half of Canada, has a cold, dry climate characterized by Arctic winds, heavy snowfall during the winter, cool, short summers in the north and warm summers in the south. Identifying port numbers for ArcGIS Online Basemap? The Flin Flon greenstone belt in central Manitoba and east-central Saskatchewan "is one of the largest Paleoproterozoic volcanic-hosted massive sulfide (VMS) districts in the world, containing 27 copper-zinc-(gold) deposits from which more than 183 million tonnes of sulfide have been mined."[22]. The current surface expression of the Shield is one of very thin soil lying on top of the bedrock, with many bare outcrops. The cookies is used to store the user consent for the cookies in the category "Necessary". The Great Lakes and the St. Lawrence Lowlands are a humid continental climate, meaning that there is little precipitation and a large temperature range. Comparable to the present-day Himalayas in size, the Grenville Mountains may have been the largest mountain range ever created on Earth. (Weather station: Ottawa Int'L. While Canada's fertility rate is 1.53 births per woman, below the population replacement rate, the population continues to grow as migration plays an increasing role in the population. Temperature range is extreme, especially in the mid-continental areas, where seasonal fluctuations can be as great as 100C.

Some of the regions natural resources include timber, such as maple, birch, aspen, fir and spruce; water from rivers and lakes created by long-retreated glaciers; and minerals, such as titanium, uranium, copper, iron, nickel, gold, zinc, silver, platinum and diamonds. While the bare rock, thin soils, muskeg and insects of the Shield made living there difficult, the development of resource-based industries, such as mining and forestry, promoted increased settlement. Climate is not only wholly dependent on these regions, however. When the Greenland section is included, the Canadian Shield is approximately circular, bounded on the northeast by the northeast edge of Greenland, with Hudson Bay in the middle.
