Question

acid mine drainage involves . a. identical processes to those that cause acid rain b. the process of rainwater from a mine carrying sulfuric acid to nearby streams and groundwater c. the intentional draining of acid from gold mines d. the disposal of acid waste left over from the mining process e. the reaction of water acidic compounds in a way that produces toxic emissions

Answer 1

Acid mine drainage involves the process of rainwater from a mine carrying sulfuric acid to nearby streams and groundwater. This can occur when water comes into contact with sulfide minerals (such as pyrite) in mine waste rock and tailings, which can generate sulfuric acid through natural oxidation processes. The acidic water can then leach heavy metals and other contaminants from the surrounding rock, resulting in pollution of nearby surface water and groundwater. Acid mine drainage is a significant environmental problem associated with many mining operations, and can have harmful effects on aquatic ecosystems, wildlife, and human health. It is not identical to the processes that cause acid rain, which is primarily caused by emissions of sulfur dioxide and nitrogen oxides from human activities such as fossil fuel combustion.
