CANADIAN SHIELD EXTRACTION OF NATURAL RESOURCES
Learning Target: I can explain the extraction of natural resources by comparing and contrasting its effects on the Canadian Shield. Essential Question: How does the extraction of natural resources such as minerals and trees affect the Canadian Shield?
Most of the Eastern half of Canada is the Canadian Shield.
Includes: gold, silver, copper, nickel, diamonds and more. The Canadian Shield contains one of Canada’s most valuable resources: minerals.
These minerals are far underground: How does Canada extract them? Mines. (The mining industry employs around 1. 5 million people. )
Diavik Diamond Mine--Northwest Territories, Canada
Mining has several effects on the environment: • Blasting and digging with heavy machinery damages land ruins the environment. • Mining releases harmful chemicals into the air which causes acid rain. • Slag (leftover rock) is dumped wherever it is convenient.
Mining in Canada
Vast forests cover almost half the land in Canada.
Canada is leading producer of timber products: lumber, paper, plywood and pulp. This natural resource is important to Canada’s economy, providing jobs and profit to Canada.
• Most timber companies cut all the trees in a given area, leaving large treeless gaps in the forest (called “clear-cutting”). Citizens are concerned that clear cutting is destroying the forests.
Clear-cutting has several effects on the environment: • • Reduces water quality. Causes erosion. Kills animals’ habitats. Heavy machinery leaves the forest floor compacted and makes it hard for new growth to start.
Instructions: Assign each group member a job. 1. Create a Venn diagram as shown. Include 3 effects of Mining and 3 effects of Clearcutting. 2. Include the causes as shown. 3. Include 1 drawing for extraction of minerals and 1 drawing for extraction of trees and color. 4. Define these words on the poster. • extraction • mining • clear-cutting • Human environment interaction. 5. Assess with rubric.
