Sudbury is an exception to the normal process of forming minerals in the Shield since the Sudbury Basin is an ancient meteorite impact crater. The Canadian Shield contains some of the oldest rocks on Earth. The Great Lakes and the St. Lawrence Lowlands are a humid continental climate, meaning that there is little precipitation and a large temperature range. Throughout the shield, there are many mining towns extracting these minerals. 3 What biome is South Florida? The climate in the boreal forest is characterized by long, very cold, dry winters and short, cool, moist summers. When they retreat, glaciers release the material theyve been transporting and the deposited sediments become the origin of soils.

The annual rainfall in Canada varies from 508mm (20) in the arid regions to 2032mm (80) in the mountains. During the Pleistocene Epoch, continental ice sheets depressed the land surface (creating Hudson Bay) but also tilted up its northeastern "rim" (the Torngat), scooped out thousands of lake basins, and carried away much of the region's soil. The Shield can be thought of as a jigsaw puzzle of different crustal blocks, sometimes known as provinces, welded together over time. The kimberlite pipes in which the diamonds are found are closely associated with cratons, which provide the deep lithospheric mantle required to stabilize diamond as a mineral. It is the world's largest continental shield covering 8 million square km (3 million square miles) and mostly consists .
