What are the causes of air pollution Class 8 answer?
Answer:
- Particulate matter (tiny particles suspended in air) Forest fires, dust storms, burning of fossil fuels and dust storms.
- Carbon dioxide and carbon monoxide. Burning of carbon rich fuels such as firewood coal and petroleum.

What is the main cause of pollution?
Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.
How common is air pollution by nature?
Air pollution by nature: This is rare and also not frequent. Air pollution by nature includes volcanoes from mountains which emit harmful gases into the air for over a prolonged period. Even release of toxic gases by nature is common.
How do natural disasters cause pollution?
Natural Causes Volcanic activities – volcanic eruptions emit a series of toxic gases (including sulfur and chlorine) as well as particulate matter (ash particles) but are usually restricted to localized areas; Winds and air currents – can mobilize pollutants from the ground and transport them over large areas;
What are the anthropogenic causes of environmental pollution?
Anthropogenic Causes. Mining and smelting – emit into the air a variety of metals adsorbed on particulate matter that is suspended in the air due to crushing & processing of mineralogical deposits;
