The mean annual temperature ranges from -4C to 0.5C; the mean summer temperature ranges from 11.5C to 14C; and the mean winter temperature ranges from -20.5C to -14.5C. The first was colonial politician Thomas D'Arcy McGee's vision, articulated in 1860, of "one great nationality bound, like the shield of Achilles, by the blue rim of ocean" encompassing "the Western mountains and the crests of Eastern . In the Canadian Shield , there are short cold winters and long hot summers . In the northern parts, the climate is very cold. The Canadian Shield constitutes the largest mass of . So far, temperatures have shifted up to 1.5 degrees Celsius, and by the end of the century temperatures could increase by 11 degrees Celsiusa lot for an ecosystem that is generally below freezing. 4 degrees F (-18 degrees C), and in the summer it is 77 degrees F (25 degrees C). Canadian Shield, one of the worlds largest geologic continental shields, centred on Hudson Bay and extending for 8 million square km (3 million square miles) over eastern, central, and northwestern Canada from the Great Lakes to the Canadian Arctic and into Greenland, with small extensions into northern Minnesota, Wisconsin, Michigan, and New York, U.S. North of this region, the Superior Province is one of Canadas most important sources of metals, including deposits of copper, gold, iron and silver. Sudbury is an exception to the normal process of forming minerals in the shield since there is significant evidence that the Sudbury Basin is an ancient meteorite impact crater. It covers much of Greenland, all of Labrador and the Great Northern Peninsula of Newfoundland, most of Quebec north of the St. Lawrence River, much of Ontario including northern sections of the Ontario Peninsula, the Adirondack Mountains[6] of New York, the northernmost part of Lower Michigan and all of Upper Michigan, northern Wisconsin, northeastern Minnesota, the central and northern portions of Manitoba away from Hudson Bay, northern Saskatchewan, a small portion of northeastern Alberta,[7] mainland Northwest Territories to the east of a line extended north from the Saskatchewan-Alberta border, most of Nunavut's mainland and, of its Arctic Archipelago, Baffin Island and significant bands through Somerset, Southampton, Devon and Ellesmere islands. The historic mapping of this area was done by Alexander Murray, who, in 185152, examined the geology around the Gananoque, Ottawa and St. Lawrence rivers, as well as the perimeter of the Shield from Kingston to Lake Superior. 1 What is the climate of Canadian Shield? in accordance with New World Encyclopedia standards. ), The Canadian Shield refers to the exposed portion of the continental crust underlying the majority of North America. The kimberlite eruptions then bring the diamonds up from over 93 miles below the surface. The ice in turn suppresses solar radiation, holding cool temperatures on nearby land into June and July. Winters are about six too eight months long. These belts range in age from 3600 to 2680 million years old. The Shield can be divided into seven geologically distinct regions sometimes referred to as provinces. Sudbury is an exception to the normal process of forming minerals in the Shield since the Sudbury Basin is an ancient meteorite impact crater. The Canadian Shield represents a small segment of Alberta's wilderness, only totaling 1.5 percent, and is completely surrounded by the Boreal Forest Natural Region. The kimberlite eruptions then bring the diamonds from over 150 kilometres (93mi) depth to the surface. Given their size and depth, the lakes gain heat in the summer months and release it during the winter. Most people there live on the temperate southwest coast . The age of the Canadian Shield is estimated to be 4.28 Ga. The Boreal Shield ecozone is a main contributor to the Canadian economy not only with its economic activities but also with its pure fresh air, water, food, recreation, and wildlife. The resulting surface consists of rocky, ice-smoothed hills with an average relief of 30 metres (100 feet), together with irregular basins, which are mostly filled by lakes or swamps. Adding TravelTime as Impedance in ArcGIS Network Analyst? First Nations-Clothing An Animal Hide 22. Showing: Canadas boreal forest (270 million hectares) stores carbon, purifies the air and water, and regulates the climate. Even in the driest month there is a lot of rain. It is an exposed subsection of the Laurentia craton signifying the area of greatest glacial impact (scraping down to bare rock) creating the thin soils. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. 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. Taiga Cold in the winter and warm in the summer, the taiga is the worlds largest land biome. Since it is such a wide region, there are varying climates, soils, natural vegetation all across the Boreal Shield. Ejecta from the meteorite impact was found in the Rove Formation in May 2007. The coast of the . The mixed coniferous and deciduous tress can survive in the poor and unproductive mountain soil, and flourish on the plateaus and in the rivers. Meanwhile on the West Coast, the warm and humid ocean currents of the Pacific collide with the coastal mountain range, resulting in orographic, or mountain-caused, rainfall that can exceed 100 inches from the autumn through to the spring. Located in the middle of the continent and stretching east to west for 750 miles, these five water bodies comprise the greatest amount of fresh surface water in the world. How tall are the mountains in the Canadian Shield? Summers in this part of Canada can bring humidity and warm temperatures, averaging 70 and 80 degrees Fahrenheit. The Canadian Shield is part of an ancient continent called Arctica, which was formed about 2.5 billion years ago during the Neoarchean era. [9] The Shield was originally an area of very large, very tall mountains (about 12,000m or 39,000ft)[10] with much volcanic activity, but the area was eroded to nearly its current topographic appearance of relatively low relief over 500 million years ago. The climate in the boreal forest is characterized by long, very cold, dry winters and short, cool, moist summers. Land in the Tundra region consists of lowlands, plateaus, mountains, and ice caps. It does not store any personal data. Climate Snowy Terrain 21. A brief description of the climate in the St. Lawrence Lowlands. Learn why looking at a set of climate models, rather than a single one, can lend confidence to decisions. This is because the Canadian Shield has unusually large areas of relatively exposed rock from the Archean eon, roughly 2.5 to 4 billion years ago. Tundra typically prevails in the northern regions. Canadas first diamond mine called Ekati opened there in 1998. First Nations-Shelter Wigwam 24.

Typical Canadian Shield: pines, lakes, bogs, and rock. Antarctic tundra occurs on Antarctica and on several Antarctic and subantarctic islands, including South Georgia and the South Sandwich Islands and the Kerguelen Islands. The annual rainfall in Canada varies from 508mm (20) in the arid regions to 2032mm (80) in the mountains. The town prospered during the silver rush of the early 20th century, before going into decline in the 1920s. The Canadian Shield is a physiographic division comprising four smaller physiographic provinces: the Laurentian Upland, Kazan Region, Davis and James. The Canadian Shield also contains iron ore, including deposits near Wawa, Ontario. The first prokaryote fossils trace to this time period, and it is speculated that this geologic period encompassed the first development of an oxygen atmosphere and the first appearance of eukaryotes. Weather in July Weather in August Long, severe winters last up to 6 months, with average temperatures below freezing. Peterson Field Guide to Geology of Eastern North America by Roberts, David & Roger Tory Peterson. Canada is home to 28% of the worlds boreal forests, with 75% of Canadian forests part of the global boreal forest ring. Later, beginning in the mid-1800s, railway construction meant blasting through Canadian Shield rock, exposing valuable minerals in the process. Download data at both local and regional scales to include data into your own work. The Canadian Shield makes up about 50 per cent of Canada. For a plain-language summary, please see Canadian Shield (Plain Language Summary).). They play an important climatic role, keeping temperatures in the area low with high humidity, interrupting winds, and reducing variable weather such as thunderstorms and cyclones. The highest temperature recorded was 113 F (45 C) at Midale and Yellow Grass, both in Saskatchewan, in 1937. Common coniferous trees include white and black spruce; jack, red, white and eastern white pine; balsam fir; tamarack; eastern hemlock; and eastern red cedar. Sun & Moon Weather Today Weather Hourly 14 Day Forecast Yesterday/Past Weather Climate (Averages) Currently: 45 F. From the Arctic peoples word for barren land, Canadas tundra region is characterized by low growing shrubs and lichen, few trees, and permafrost soil. One of the largest of these mountain-making events was the Grenville Orogeny. Substantial gold discoveries were also made in Ontario at Kirkland Lake in 1906 and Timmins in 1912, and in Qubec at Rouyn-Noranda in 1920.

Deciduous trees include red and mountain maple; white and paper birch; trembling aspen; black ash; and balsam poplar. The Canadian Shield is the part of the North American craton that is exposed. Our editors will review what youve submitted and determine whether to revise the article. In total, the Canadian Shield covers approximately 8 million square kilometers. In places the old mountain ranges may be recognized by hills several hundreds of metres in height. In the southern parts, the climate is seasonal; the average temperature in the winter is -. What is the annual precipitation in Canada? It is the Earth's greatest area of exposed Archean rock. This process is known as the winterization of summer. 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. In addition to its rich natural resources, including substantial deposits of such mineral ores as nickel, gold, silver, and copper, and pristine northern ecosystems, the Canadian Shield also serves as a fertile area for human beings trying to better understand the origin of life. The growing season is only about 60 days and in the winter the sunlight hours are about 5.5 hours while in the summer 18.5 hours. Some of this material was deposited on the shield when the ice melted, but the bulk of it was carried southward to be deposited south and southwest of the Canadian Shield. Typical Canadian Shield: pines, lakes, bogs, and rock. Recently scientists determined the geographical elements of the Rockies impact climate as far away as Norway. This climate is considered to be Dfb according to the Kppen-Geiger climate classification. Myth: Logging causes deforestation. 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. [13] Much of the granitic rock belongs to the distinctive tonalitetrondhjemitegranodiorite family of rocks, which are characteristic of Archean continental crust. Two main climate types are found in this region. What is the climate in the boreal forest? The human population tends to be scarce in the taiga, but many mammals are present in the area, such as caribou, wolverines, weasels, minks, otters, grizzlies, and black bears.

An outline of the Canadian Shield would give the appearance of a warrior's shield or a giant horseshoe. Powered by Create your own unique website with customizable templates. How would you describe the Canadian Shield? In geology, a shield is generally a large area of exposed Precambrian crystalline igneous and high-grade metamorphic rocks that form tectonically stable areas and that normally form the nucleus of continents. Other evidence of past glacial structures include striations (lines scraped into rocks) and drumlins (long hills of glacial sediment). The growing season of about 120 days coincides with . Typical Canadian Shield: pines, lakes, bogs, and rock. Since Vancouver is near water, their climate is based on it too. North of the boreal forest is the Arctic tundra ecozone, characterized by low-growing vegetation and few to no trees. 3 What kind of climate does the Canadian Shield have? The climate in Quebec is cold and temperate. 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. The climate here features long, cold winters and short, cool summers. The location in regards to east and west does not really matter as much as north and south. The shield is one of the world's richest areas in terms of mineral ores. Canadian Shield: As observed on the map, the Canadian Shield, covering the eastern half of Canada's landmass is an ancient bedrock base of gneiss and granite covered by a shallow layer of soil. Canadian Shield is a large area of Precambrian rock that forms the core of Canada. The Canadian Shield is dominated by the boreal forest ecosystem. Climate.
