4. Combustion or burning of waste.
5. Natural disasters like volcanoes and forest fires.
6. Industries and factories emit dust and pollutants.

Answer 2

Three Factors Responsible for Air Pollution:

1. Vehicle Emissions: Smog and respiratory issues are caused by the discharge of toxic gases like carbon monoxide and nitrogen oxide by cars, trucks, and buses.
2. Deforestation: Cutting down trees reduces oxygen production and increases CO₂ levels, worsening global warming.
3. Burning of Fossil Fuels: Burning coal, oil and gas for cooking and electricity releases greenhouse gases that exacerbate global warming.
