Which type of pollution includes CFCs and smog? Air, land, water or volcanic

Understanding the Types of Pollution

1. Air Pollution: This type of pollution occurs when harmful substances, including gases, dust, or smoke, are introduced into the Earth's atmosphere. These substances can have severe health effects on humans and the environment.

2. Land Pollution: This involves the degradation of the Earth’s land surfaces. It is primarily caused by human activities such as improper disposal of waste, the use of pesticides, and industrial activities.

3. Water Pollution: This refers to the contamination of water bodies (like rivers, lakes, and oceans) due to various pollutants. It often results from industrial waste, sewage, and agricultural runoff.

4. Volcanic Pollution: This type of pollution is caused by volcanic eruptions, which release ash, sulfur dioxide, and other harmful substances into the atmosphere.

Identifying the Correct Type of Pollution

• Chlorofluorocarbons (CFCs) are chemicals once commonly used as refrigerants and in aerosol sprays. They contribute to the depletion of the ozone layer, which is a significant concern regarding air quality and atmospheric health.

• Smog is a type of air pollution that is a mixture of smoke and fog, often intensified by weather conditions. It contains various harmful pollutants and poses health risks.

Conclusion

Based on the classification and properties of each pollution type, the correct answer is Air Pollution. CFCs and smog are both significant contributors to air pollution, impacting environmental and human health.
