Question

Underground mining removes minerals from deep in the earth. Miners use blasting to separate the "waste" from the mineral deposit. Which statement best describes an environmental consequence of this process? (3 points)

Underground mining activities often cause noise pollution.
Acid mine drainage kills plants and animals around the mine.
High salinity of wastewater reduces soil fertility and vegetation.
Soil is removed by the force and pressure of the drilling process.

Answer 1

Explanation: Acid mine drainage kills plants and animals around the mine is the statement that best describes an environmental consequence of underground mining. Acid mine drainage is a byproduct of the mining process that occurs when water reacts with minerals in the rock, creating acidic and toxic conditions. This can have a significant impact on the local ecosystem, killing plants and animals that live in and around the mine, and contaminating water sources. It is important for mining companies to manage and mitigate the impact of acid mine drainage to minimize its environmental consequences.
