CANADIAN SHIELD
Canadian Shield
More than half of Canada is covered by the Canadian shield and it contains some of the oldest rocks in the world. The Canadian Shield had once been a major mountain region but is currently relatively flat. It is made up of metamorphic and igneous rock, that contains valuable metallic mineral such as lead, gold, nickel, copper zinc, and they have recently discovered diamonds in some areas. However, mining these minerals comes with an "environmental cost". In conclusion, the Canadian shield is relatively flat with rolling hills composed of igneous and metamorphic rock that contains several valuable minerals.
