The current surface expression of the Shield is one of very thin soil lying on top of the bedrock, with many bare outcrops. ). 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.

The crust, also known as the North American Craton, extends from northern Mexico to Greenland and consists of hard rocks at least 1 billion years old. Canadas largest iron ore deposit, however, is known as the Labrador Trough or New Qubec Orogen, and runs in a strip through northeastern Qubec and western Labrador. The Canadian Shield is part of an ancient continent called Arctica, which was formed about 2.5 billion years ago during the Neoarchean era. Image by Jon Sullivan. Learn about ANUSPLIN, the interpolation tool used to create gridded historical datasets. 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.

What Is the Climate of the Canadian Shield? - Reference.com The Canadian Shield is a collage of Archean plates and accreted juvenile arc terranes and sedimentary basins of the Proterozoic Eon that were progressively amalgamated during the interval 2.451.24 Ga, with the most substantial growth period occurring during the Trans-Hudson orogeny, between c. 1.901.80 Ga.[5] The Canadian Shield was the first part of North America to be permanently elevated above sea level and has remained almost wholly untouched by successive encroachments of the sea upon the continent. In this area, climate has a huge impact on the landforms. Lakes are largely the result of glacial erosion during the last ice age. Precipitation collects acidic particles and gases and becomes acidic. Today, Canada's 348 million hectares of forest lands represent about 9% of the world's forest cover, but account for only 0.3% of global deforestation. This region does overlap other regions of Canada, including the Cordillera and the Canadian Shield. Canada's topography is dominated by the Canadian Shield, an ice-scoured area of Precambrian rocks surrounding Hudson Bay and covering half the country. The southern temperate regions receive up to 1016mm (40) of rainfall evenly throughout the year. The lowlands of the Canadian Shield have soggy soil suitable for planting trees, but it contains many marshes and bogs. During this glaciation, the Shield was covered by the Laurentide Ice Sheet, a giant expanse of ice as much as 3 km thick. 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. What kind of rocks are in the Canadian Shield? This region has short summers. The kimberlite eruptions then bring the diamonds from over 150 kilometres (93mi) depth to the surface. East of the Shield is the maritime area, separated from the . How would you describe the Canadian Shield? Major Climates in Canada's Different Regions - Study.com With an area close to 5 million km 2, the Canadian Shield covers 48 per cent of Canada's land surface (including freshwater lakes and Arctic islands). Adapting to a changing climate requires confronting and dealing effectively with a wide range of uncertainties. 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. Climate - Canadian Shield We also use third-party cookies that help us analyze and understand how you use this website. 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. Globally, the presence of the Rockies pushes wind south.

The rocks that now form the surface of the Shield were once far below the Earth's surface. boreal climate The climate associated with the boreal (taiga) forest zone of Eurasia, where it extends to 6570N in the west and 50N in the east, and North America, where it extends from the fringe of the tundra southwards to 55N in the east. It is filled with substantial deposits of nickel, gold, silver, and copper. Several factorsnamely, the solar elevation angle, day length, and snow coverconspire to produce this cold climate. The Canadian Shield constitutes the largest mass of . First Nations-Shelter Wigwam 24. 4 How many hours of Daylight does the Canadian Shield have? They write new content and verify and edit content received from contributors. The Northern part gets very little rain and snow each year. Climate Snowy Terrain 21.

These weathering processes were interrupted by a number of ice ages occurring over the last 2.5 million years. The high pressures and temperatures at those depths provided ideal conditions for mineralization. The shield is considered to have been originally an area of very large mountains and much volcanic activity, but over the millennia the area was eroded to its current topographic appearance of relatively low relief (984 to 1,968.5 feet above sea level) with diverse ridges and low mountain ranges. Wolves, black and grizzly bears and the lynx are the larger predators. Clothing allows us to stay comfortable in areas with cooler temperatures. Occurring about 1 billion years ago, the Grenville Orogeny created the Grenville Mountain Range, stretching from Qubec through Ontario and down the eastern side of the continent to Texas. Age. 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. The Craton stretches from Greenland to Mexico. It is the Canadian breadbasket and an area that is also rich in petroleum, gas, and other mineral resources. Click here to learn more.

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. 3 What kind of climate does the Canadian Shield have? Canadian Biodiversity: Ecozones: Taiga Shield This cookie is set by GDPR Cookie Consent plugin. During the Pleistocene Epoch, continental ice sheets depressed the land surface (creating Hudson Bay) but also tilted up its northeastern "rim" (the Torngat), scooped out thousands of lake basins, and carried away much of the region's soil. Of all the biomes with forests, the boreal forest is projected to experience the largest temperature shift. Shaped like a horseshoe or the shields carried during hand-to-hand combat the Canadian Shield extends from Labrador in the east to include nearly all of Qubec, much of Ontario and Manitoba, the northern portion of Saskatchewan, the northeast corner of Alberta, much of the Northwest Territories and Nunavut and into the Arctic Archipelago. New to climate data?
