Question

The significant natural causes of air pollution are:

• A. volcanic eruptions
• B. forest fires
• C. both A and B both
• D. none of the above

Answer 1

The correct option is C both A and B both

Volcanic eruptions are a major source of natural air pollution. When an eruption occurs, it produces tremendous amounts of harmful chemical substances, which are released into the atmosphere and can be picked up by winds to be dispersed over large areas.

Forest fires are a considerable source of pollutants. Their effects on the air quality may be of relatively short-term duration, but considerable.
