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. Throughout the shield, there are many mining towns extracting these minerals. The average temperature ranges from -15 to -35 celcius. Climate. The northeastern portion, however, became tilted up so that, in northern Labrador and Baffin Island, the land rises to more than 1,500 metres (5,000 feet) above sea level. Winters are about six too eight months long. Statistical data | Natural Resources Canada The Shield was originally an area of very large, very tall mountains (about 12,000 metres or 39,000 feet) with much volcanic activity, but over hundreds of millions of years, the area has been eroded to its current topographic appearance of relatively low relief. During the day, desert temperatures rise to an average of 38C (a little over 100F). Most often they are bordered by belts of folded Cambrian rocks. Temperate grassland 5. savanna (tropical GL) 6. The Canadian Shields most notable physical features are thousands of small lakes, thin layers of soil and rolling hills. 3 What kind of climate does the Canadian Shield have? This arrangement was caused by severe glaciation during the ice age, which covered the Shield and scraped the rock clean. While gold mines still operate near Kirkland Lake and Timmins, there are no longer any active mines in Colbalt or Rouyn-Noranda a reality not uncommon for early mining towns. Overview of Climate Change in Canada If you were to overlay a map of the Canadian Shield with this week's population density map, you would see that Canada's major population centers do not extend into the Shield. It snows approximately nine months a year, leaving three months for a cool, short summer (average temperature 14.8C). The region gets around 18 inches of rain each year. The location in regards to east and west does not really matter as much as north and south. 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]. Common coniferous trees include white and black spruce; jack, red, white and eastern white pine; balsam fir; tamarack; eastern hemlock; and eastern red cedar. Ontario is the most populous province in Canada. The Canadian prairies generally receive about 12 to 15 inches of annual precipitation in the semi-arid areas, while the continental regions receive a bit more, averaging 16 to 20 inches a year. What does it mean that the Bible was divinely inspired? The Canadian Shield is dominated by the boreal forest ecosystem.
