Which term refers to the process of damaging air, water, or land quality through pollution?

• A. Contamination
• B. Erosion
• C. Pollution
• D. Degradation

Answer: (C)

The idea here is how harmful substances enter and affect the environment. Pollution specifically refers to the process of introducing contaminants into air, water, or land, leading to damage or degradation of those environments. It covers how emissions, runoff, waste, and chemicals actively change the quality of the environment in a harmful way. Contamination describes the presence of pollutants in a place, which is related but focuses on the state of being polluted rather than the ongoing act of causing pollution. Erosion is the physical wearing away of soil by wind or water, not chemical or biological contamination. Degradation is a broad decline in quality that can result from many factors, not necessarily the direct process of polluting.
