Student answers will vary. An abandoned strip mine will partially recover over time. Without human intervention, however, its recovery will be minimal.
  • The strip is likely to partly recover, but never return to its original state.
  • Explain why mining has such a large impact on the environment.
  • Predict what will happen to an abandoned strip mine over time.
  • What are three ways that minerals are used?
Student answers will vary. Possible answers include construction, technology, and industry.
  • What are three ways that minerals are used?
  • Large scale extraction is vital to the economy of mining towns.
  • dredging sediments from the water bottom
  • Predict what will happen to an abandoned strip mine over time.
Surface mining destroys all plant life in the area the mine occupies. Plants living in the area where the surface mine is to be located are removed. After the surface mine is no longer productive, plants may eventually return to the area, but typically some human efforts at reclamation are required to restore the environment to some level of productivity.
  • improved ecosystem health
  • the complete loss of plant life in the area occupied by the surface mine
  • Explain why mining has such a large impact on the environment.
  • Explain how surface mining affects plant life.
