The Canadian Shield
The Canadian shield is centered on Hudson’s Bay over eastern, central, and northwestern Canada.
Major cities that are located in the Canadian Shield are Sudbury, Ottawa, Montreal, Quebec, Iqaluit, Thunder Bay, and Winnipeg.
The Canadian shield was formed throughout 3 billion years through the process of plate tectonics, glaciation and erosion's. Some types of rocks include metamorphosed granite, sedimentary and igneous rocks. The most noticeable features of the Canadian shield are the thousands of small lakes, rocks, plateaus, wetlands and the rolling hills.
Examples of rock formations in the Canadian Shield
The Canadian Shield is based on mining and economics, It is filled with substantial deposits of nickel, gold, silver, and copper. Many mining towns can be found in the Shield, collecting these minerals. Sudbury, Ontario, is the largest and most well known.
Falling ambient pressure will release methane more rapidly from the coal seam into the atmosphere of the mine and may also occur in areas of the mine not typically susceptible to methane accumulation.
The Canadian Shield is affected by climate change because as the north warms, animals such as caribou are able to migrate to areas where they can eat and raise their young in the spring. The ice caps are also melting at a faster rate, making it more difficult for polar bears to get food.
