The Canadian Shield is a large area of ancient rocks that forms the core of North America, covering much of central Canada and providing resources such as timber and minerals.
Step-by-step explanation:
The Canadian Shield is a vast geological shield covered by a thin layer of soil that forms the nucleus of the North American continent. It is found mainly in central Canada, surrounding the Hudson Bay and stretching from the Great Lakes to the Arctic Ocean, and it covers parts of several provinces and territories. The Canadian Shield is rich in minerals, making it an important region for Canada's mining industry, and it's also home to extensive boreal forests that are a crucial source of timber. This area is crucial to Canadian industries and exports including timber and minerals like nickel, gold, silver, and copper.
