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?

1. The type of ecosystem that existed in the Copper Basin area before mining began was a deciduous forest ecosystem.<br />2. There were no plant roots to hold soil in place because all the trees were cut down for fuel.<br />3. The soil became contaminated with sulfuric acid due to the burning of trees, which released sulfur dioxide gas. This gas reacted with water vapor in the air to form sulfuric acid, which then fell back to Earth in rain and soaked into the soil.<br />4. "Land reclamation" means the process of creating new land from oceans, riverbeds, or lakes, or the process of converting unproductive land into productive land.<br />5. As new plants continue to grow, they will help prevent further erosion, dead leaves will decompose and enrich the soil, and small animals will begin returning to the area.<br />6. It will take at least 100 more years for the original ecosystem to return to the Copper Basin due to the slow process of soil enrichment and the gradual return of animal life.<br />17. The natural resources compromised in this case study are the forest ecosystem, soil, and animal life.

Explicar

## Step1<br />The first question asks about the type of ecosystem that existed in the Copper Basin area before mining began. The passage clearly states that the Copper Basin was once a deciduous forest ecosystem.<br /><br />## Step2<br />The second question asks why there were no plant roots to hold soil in place once mining began. The passage explains that all the trees were cut down for fuel, which led to the destruction of the plant roots that held the soil in place.<br /><br />## Step3<br />The third question asks how the soil became contaminated with sulfuric acid. The passage explains that the burning of trees released sulfur dioxide gas, which reacted with water vapor in the air to form sulfuric acid. This acid then fell back to Earth in rain and soaked into the soil, contaminating it.<br /><br />## Step4<br />The fourth question asks what "land reclamation" means. The passage defines land reclamation as the process of creating new land from oceans, riverbeds, or lakes, or the process of converting unproductive land into productive land.<br /><br />## Step5<br />The fifth question asks about the changes that might occur in the area as new plants continue to grow. The passage suggests that as new plants grow, they will help prevent further erosion, dead leaves will decompose and enrich the soil, and small animals will begin returning to the area.<br /><br />## Step6<br />The sixth question asks why it will take so long for the original ecosystem to return to the Copper Basin. The passage suggests that it will take at least 100 more years for a true forest ecosystem to return to the Copper Basin due to the slow process of soil enrichment and the gradual return of animal life.<br /><br />## Step7<br />The seventeenth question asks about the natural resources that are compromised in this case study. The passage identifies the natural resources compromised in this case study as the forest ecosystem, soil, and animal life.
