Question 5:

Which of the following is an environmental concern associated with fossil fuel extraction and processing?

A) Reduced carbon dioxide emissions
B) Enhanced water quality
C) Soil enrichment
D) Air and water pollution

Show Answer

Explanation: The correct answer is D) Air and water pollution. Fossil fuel extraction and processing can lead to air and water pollution, contributing to environmental degradation. Activities such as drilling, mining, and refining can release pollutants, including greenhouse gases, volatile organic compounds, sulfur compounds, and heavy metals, which can have adverse effects on air quality, water bodies, ecosystems, and human health.
