The North American craton is the bedrock forming the heart of the North American continent and the Canadian Shield is the largest exposed part of the craton's bedrock. Typical Canadian Shield: pines, lakes, bogs, and rock. If underground areas are included, the Canadian Shield covers even more area. This arrangement was caused by severe glaciation during the ice age, which covered the Shield and scraped the rock clean. 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. Ejecta from the meteorite impact was found in the Rove Formation in May 2007. This Natural Region experiences a harsh climate; winters are generally quite long that are influenced by polar and arctic weather systems with 40 percent of the annual . The Canadian Shield contains some of the oldest rocks on Earth. The climate in the Canadian Shield varies through its vast scenery and location. In the Arctic the presence of sea ice on the ocean interacts with the atmosphere, limiting the ability of wind to create large waves or exchange heat, vapor, or gasses between the land and sea. Given their size and depth, the lakes gain heat in the summer months and release it during the winter. Explore all the available data through high resolution maps and graphs. Adapting to a changing climate requires confronting and dealing effectively with a wide range of uncertainties. What kind of rocks are in the Canadian Shield? Home Page > Population.

The Northern part gets very little rain and snow each year. Many of Canada's major ore deposits are associated with Precambrian volcanoes. Mammals. Canadian weather is harsh and cold during the long winter months but is more varied during other seasons. Canadas famous Rocky Mountain Range influences more than the Canadian climate. In the case of the Grenville Mountains, its estimated that tens of kilometres of rock may have been worn down. Image by Jon Sullivan. The Canadian Shield is rich in natural resources, including minerals, forests and freshwater. The region has numerous pine forests and sand dunes, the perfect habitat for unique plant life. In the southern parts, the climate is seasonal; the average temperature in the winter is -. Tundra typically prevails in the northern regions. [8] The multitude of rivers and lakes in the region is classical example of a deranged drainage system, caused by the watersheds of the area being disturbed by glaciation and the effect of post-glacial rebound. 4 degrees F (-18 degrees C), and in the summer it is 77 degrees F (25 degrees C). APPALACHIAN REGION Climate This region is affected by 2 currents, the Labrador current and the Gulf Stream. This vast region, with its store of forests, waterpower, and mineral resources, is being increasingly developed.

Given its size, it stretches across the provinces and territories of Nunavut, Ontario, Saskatchewan, Quebec, Labrador, and the Northwest Territories, average temperatures within the Shield vary greatly. The current surface expression of the Shield is one of very thin soil lying on top of the bedrock, with many bare outcrops. The Craton stretches from Greenland to Mexico. This area lies between the western border of the Shield and the Canadian Rockies. The Canadian Shield, a hilly region of lakes and swamps, stretches across northern Canada and has some of the oldest rocks on Earth. The Canadian Shield is so large that the climate varies across it. The Ekati and Diavik mines are actively mining kimberlite diamonds. The multitude of rivers and lakes throughout the region is caused by the watersheds of the area being so young and in a state of sorting themselves out with the added effect of post-glacial rebound. Ont., Canada). Kimberlites formations where diamonds can be located are scattered throughout the Shield, with the largest deposit located near Lac de Gras, Northwest Territories, about 300 km northeast of Yellowknife. ), The Canadian Shield refers to the exposed portion of the continental crust underlying the majority of North America. During the Archean, processes were also set in motion that prepared the foundation for multicellular life, with the development of an oxygen atmosphere and, it is speculated, possibly the appearance of the first eukaryotes around 2.7 billion years ago, near the end of the Archean (Mayr, 2001). The Canadian Shields most notable physical features are thousands of small lakes, thin layers of soil and rolling hills. First Nations-Food Beaver (Sometimes Eaten As Food) 23.

Distinct for its mix of coniferous and deciduous trees, high latitude location, and ability to grow in sub zero temperatures 6 to 8 months per year, boreal forests cover vast expanses in Canada, Alaska, and Russia. Not only does Canada have the longest coastline in the world, its also the only country to border three oceans: the Arctic, Atlantic, and the Pacific. The Canadian Shield also contains iron ore, including deposits near Wawa, Ontario.

From the Arctic peoples word for barren land, Canadas tundra region is characterized by low growing shrubs and lichen, few trees, and permafrost soil. The Canadian Shield is a U-shaped subsection of the Laurentia craton signifying the area of greatest glacial impact (scraping down to bare rock) creating the thin soils. The Canadian Shield constitutes the largest mass of . Climate is not only wholly dependent on these regions, however. Climate: Northwest Territories. Climate-Data.org. Transitional between the tundra and the boreal forests is the Northern Canadian Shield Taiga ecoregion, characterized by low-lying bushes because of the increasingly severe weather and unsuitable soil conditions (WWF, 2001). Most temperate forests dont get as much rainfall as tropical rainforests, but they do get enough rainabout 30 to 60 inches each yearto grow big trees. The Canadian Shield, particularly the portion in the Northwest Territories, has recently been the site of several major diamond discoveries. The Canadian Shield stretches from Labrador to the Arctic. Given its vast latitudinal reach and widely varying geography, it is unsurprising that Canada experiences several different climatic regions. The first modern hard-rock mine in the Canadian Shield, near Madoc, Ontario, opened in 1866 after gold was found there. Past weather data includes: temperature, snow, snow on ground, precipitation, rain, wind speed and direction, heating and cooling degree days, visibility, humidex, wind chill and relative humidity in Canada. * Each location provided here corresponds to a point location in Canada. 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]. It forms the North American Craton (or Laurentia), the ancient geologic core of the North American continent. What is the climate in the boreal forest? Due to technological advancements, humans have been able to modify their environment and adapt to many different places. It has over 150 volcanic belts (now deformed and eroded down to nearly flat plains) that range from 600 to 1,200 million years old. During the Pleistocene Epoch (2.6 million to 11,700 years ago), the vast continental glaciers that covered northern North America had this region as a centre.

Some of the highest producing hydroelectric dams include Churchill Falls, Labrador, and James Bay, Qubec. The Shield is covered in parts by vast boreal forests in the south that support natural ecosystems as well as a major logging industry. The high pressures and temperatures at those depths provided ideal conditions for mineralization. (One of the five factors that influence climate.) This is the Athapaskan "land of little sticks" that stretches from Labrador to Alaska and from Siberia to Scandinavia.
