- Copper Basin , Tennessee The Copper Basin is a large area of land in southeastern Tennessee. The zhea gets its name from the copper mining that took place there about 150 years ago. The Copper Basin was once a deciduous forest ecosystem. Now, the area consists mostly of bare hills with deep gullies caused by enceion. What happened in the Copper Basin? Read the following passage. Then answer the questions that follow. The Copper Basin When people discovered copper ore in the Copper Basin, mining comparies began to dig up and process this ore. Copper ore contains many unwanted materials mixed with the coppermetal. To remove the unwanted materials, the mining companies would smelt the ore, or heat it in a furnace. The smelters looked like huge, open fire pits. To keep the smelters burning, all the surrounding trees were cut down and used as fucl. The burning ose released sulfur dioxide gas. In the air, the sulfur dioxide reacted with water vapor to form sulfuric acid .The acid fell back to Earth in rain and soaked into the soil. The acid in the soil killed plants as they began to grow where the trees had been cut down. Animals that depended on the trees and other forest plants for food and shelter left the area And with no plant roots left to hold down the soil, runoff from rain eroded the land. In just a few years, the entire focest coosystem in the Copper Basin was destroyed. Beginning in the 1930s.government agencies tried to replant part of the Copper Basin, but the soil was still too acidic Most of the plants died.Then nearly 50 years later land reclamation scientists tried again, using new planting methods. They were more successful, and plants began to repopulate parts of the Copper Basin. Their roots helped prevent further erosion.Dead leaves decomposed and enriched the soil. Small animals began returning to the area. But progress is slow. Scientists estimate that it will take at least 100-more years for a true forest ecosystem to return to the Copper Basin. Answer the following questions on a separate shoet of paper. 1. What type of ecosystem existed in the Copper Basin area before mining began? 2. Once mining began why were there no plant roots to hold soil in place? 3. How did the soil become contaminated with sulfuric acid? 4. What does "land reclamation" mean? 5. What changes might occur in the area as new plants continue to grow? 6. Why do you think it will take so long for the original ecosystem (17. What natural resources are compromised, in this case study?
