The Canadian Shield

The Canadian Shield is a vast, ancient geological region that forms the core of North America, covering around 3 million square miles. Composed mainly of Precambrian rock, it is characterized by rugged terrain, numerous lakes, and thin, nutrient-poor soils. Its stability over billions of years has made it a source of valuable minerals like gold, copper, and nickel. The landscape features rocky outcrops, forests, and lakes, shaping much of Canada's geography. The Shield plays a crucial role in the country's natural resources and ecosystem, serving as a foundation on which much of Canada's landmass is built.
