Globally, the presence of the Rockies pushes wind south. Since it is such a wide region, there are varying climates, soils, natural vegetation all across the Boreal Shield. What is the climate in northern Canadian Shield? It snows approximately nine months a year, leaving three months for a cool, short summer(average temperature 14.8C). Comparable to the present-day Himalayas in size, the Grenville Mountains may have been the largest mountain range ever created on Earth. 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. The ice in turn suppresses solar radiation, holding cool temperatures on nearby land into June and July. Without mountains, forests, valleys, cliffs, or large rivers to influence wind, precipitation, or sun cover, tundra is home to dry, cold temperatures that do not rise above 50oF during its summer and ten months of below freezing. The Canadian Shield constitutes the largest mass of exposed Precambrian rock on the face of Earth. The average temperatures range from 59 degrees F (15 degrees C) in the summer to -31 degrees F (-35 degrees C) in winter. The Labrador Current brings cold water south of the Arctic.

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. The population in the Canadian Shield is somewhere around 7 million . Coldness is the dominant climatic factor in taiga ecosystems, although a surprising diversity of climates exists. 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 resulting climate is ideal for coniferous red wood forests, where some of the worlds oldest trees are still thriving today. Also known as: Canadian continental shield, Canadian-Greenland Shield, Laurentian Shield, Precambrian Shield. The Canadian Shield is the part of the North American craton that is exposed. It also includes in Canada the central/northern portions of Manitoba away from Hudson Bay and the Great Plains, northern Saskatchewan, and a small portion of northeastern Alberta, as well as the mainland northern Canadian territories to the east of a line extended north from the Saskatchewan/Alberta border (Northwest Territories and Nunavut) (HCF, 2007). Who wrote the music and lyrics for Kinky Boots? APPALACHIAN REGION Climate This region is affected by 2 currents, the Labrador current and the Gulf Stream. 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. The rest of the region has coarse soil that does not hold moisture very well and is frozen all year round. The climate of the boreal forest is characterized by strong seasonal variation with short, moderately warm and moist summers and long, extremely cold and dry winters. [11][12] Erosion has exposed the roots of the mountains, which take the form of greenstone belts in which belts of volcanic rock that have been altered by metamorphism are surrounded by granitic rock. Land in the Tundra region consists of lowlands, plateaus, mountains, and ice caps. Weathered Precambrian pillow lava in the Temagami Greenstone Belt, Folded Precambrian gneiss of the Canadian Shield in Georgian Bay, Ontario, Typical Canadian Shield landscape: spruce, lakes, bogs, and rock. The boreal forest (or taiga) is the worlds largest land biome. Climate is not only wholly dependent on these regions, however. The western portion of the Eastern Canadian Shield Taiga ecoregion is composed of the Larch Plateau and the Richmond Hills, with elevations ranging from 150 m near the coast of James Bay to 450 m further east.

The kimberlite eruptions then bring the diamonds up from over 93 miles below the surface. The Canadian Shield is rich in natural resources, including minerals, forests and freshwater. Canadian Shield is a large area of Precambrian rock that forms the core of Canada. The Coast Mountains puncture cloud cover and force wet, westerly winds upwards, with some areas experiencing up to 170 inches a year of precipitation. The high pressures and temperatures at those depths provided ideal conditions for mineralization. Most often they are bordered by belts of folded Cambrian rocks.

The rest of the region has coarse soil that does not retain moisture well and is frozen with permafrost throughout the year. 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. The location in regards to east and west does not really matter as much as north and south. Throughout the Shield there are many mining towns extracting these minerals. This results in very hot summers and very cold winters. The Canadian shield is centered on Hudson's Bay over eastern, central, and northwestern Canada. This arrangement was caused by severe glaciation during the ice age, which covered the Shield and scraped the rock clean. In the southern parts, the climate is seasonal; the average temperature in the winter is -.
