The underlying rock structure also includes Hudson Bay and the submerged area between North America and Greenland. 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. Vegetation. Sudbury is an exception to the normal process of forming minerals in the Shield since the Sudbury Basin is an ancient meteorite impact crater.

Weather in July Weather in August While the area still suffers strong winds, the incidence of cyclones is greatly reduced. The Canadian Shield is a huge rock formation. Climate The climate of the Canadian Shield varies. When the earth deforms as a result of these collisions, geologists call the deformation process an orogeny. Orogenies cause the earth to thrust upward, creating mountain ranges. The rest of the region has coarse soil that does not retain moisture well and is frozen with permafrost throughout the year. At 5 million km2, the Shield makes up roughly 50 per cent of Canadas land mass. 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 a collage of Archean plates and accreted juvenile arc terranes and sedimentary basins of the Proterozoic Eon that were progressively amalgamated during the interval 2.45-1.24 Ga, with the most substantial growth period occurring during the Trans-Hudson orogeny, between c. 1.90-1.80 Ga. [5] The Canadian Shield was the first Precipitation comes in the form of rain, snow, sleet, or hail. It is the Earth's greatest area of exposed Archean rock.

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. 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. . Home Page. Reproduced with the permission of the Minister of Public Works . 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. The resulting climate is ideal for coniferous red wood forests, where some of the worlds oldest trees are still thriving today. Located just below the tundra region, these young forests are in constant renewal due to the natural occurrence of forest fire and insect infestation.

The ice in turn suppresses solar radiation, holding cool temperatures on nearby land into June and July. . What is the climate of the Canadian Shield region? 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.

Unique geographic features and formations can significantly impact the climate in an area. Lakes are largely the result of glacial erosion during the last ice age. 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. Although the Arctic is technically a desert due to its low precipitation of 10 inches annually - by comparison the Gobi Desert has 7 inches per year - Canadas only other desert, the Okanagan, is home to traditional desert fare such as cactus, rattlesnakes, and a hot, arid, climate that enjoys 2,000 hours of sunlight a year.
