Get an original essay Canadian Shield The Canadian Shield was formed in the Precambrian area by volcanoes. Since then, the Canadian Shield has been weathered and eroded by glaciers. Today, the Canadian Shield is the largest and oldest landform in Canada. (MAP BY HOLLY O'ROURKE/THE CANADIAN ENCYCLOPEDIA) The Canadian Shield is rich in minerals, which is why it is often known as the “warehouse” of minerals. We use the Canadian Shield to mine lead, gold, copper, nickel, etc. However, since the Canadian shield is popular; there has been a depletion of the amount of minerals due to excessive extraction. Mined minerals provide materials for the manufacturing industry. Not to mention; there are various tools used to extract the minerals, which also results in pollution. Soil/Vegetation In Canada, the climate varies quite a bit. The variable climate results in different soil types, where two processes called leaching and calcification play an important role in Canadian soils. Leaching occurs when there is excessive rainfall, where rain water draws out nutrients that plants need in the soil. However, leached soils can be used for agriculture, only if fertilizers are added to the soil. Additionally, calcification occurs when the climate has less precipitation (dry). Because the soil cannot hold moisture (water evaporates), nutrients are drawn out to form rich topsoil, which can be poisonous to plants. The consequences of different soils result in different types of vegetation. Forests Some examples of forests in Canada are: boreal and taiga forest, mixed forest, etc. Boreal Forest and Taiga Boreal forest and taiga surround part of Hudson Bay. The forest consists of white and black firs, pines, firs, etc. Precipitation in this area causes leaching, so cultivated trees can survive in cooler climates. However, tree needles are acidic, which makes the soil unsuitable for other trees. “Taiga landscape in Quebec, Canada, dominated by black spruce” Mixed forest Mixed forest is found in eastern Canada. The forest consists of maple, beech, ash, oak, birch, spruce, spruce, etc. The topsoil in the mixed forest is rich in nutrients and the soil absorbs water well. Precipitation is not excessive, so the soil is not subject to leaching or calcification. One way we use land is agriculture, or in other words; agriculture. The soil in the mixed forest is great for farming due to the rich soil and ability to absorb water. However, the soil of the boreal forest and taiga is acidic, unsuitable for agriculture. As mentioned before, due to the pollution created, the climate is changing (global warming). Terrain depends on climate, so a warmer climate means more precipitation. The result of increased rainfall is bleeding, which will eventually make the soil unacceptable for agriculture. Forests, however, are mainly used for lumber. Boreal and taiga forest, as well as mixed forest, provide resources to logging companies. There are fewer trees in these regions due to logging. Not to mention that tools and woodworking create pollution. Oceans Canada is surrounded by the Pacific and Oceans 21, 2018
