Question

black lung disease, waste heaps, and acid drainage are problems associated with select one: a. natural gas drilling. b. nuclear power plants. c. coal mining. d. solar power sites.

Explanation:

Black lung disease is caused by inhaling coal dust in coal - mining environments. Waste heaps are common in coal - mining areas where mined coal is stored or waste material is piled up. Acid drainage occurs when water interacts with sulfide - bearing materials in coal mines, releasing acidic water. These problems are not associated with natural gas drilling, nuclear power plants, or solar power sites.

Answer:

C. coal mining
