The Short Answer: 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.

What is pollution definition for Class 3?
Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash. They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land.
What are the 3 main causes of air pollution?
Vehicle emissions, fuel oils and natural gas to heat homes, by-products of manufacturing and power generation, particularly coal-fueled power plants, and fumes from chemical production are the primary sources of human-made air pollution.
How do we cause pollution?
Human air pollution is caused by things such as factories, power plants, cars, airplanes, chemicals, fumes from spray cans, and methane gas from landfills. One of the ways that humans cause the most air pollution is by burning fossil fuels. Fossil fuels include coal, oil, and natural gas.
How is pollution caused?
These pollutants include Particulate Matter (very small particles that get into our respiratory system), nitrogen oxide and sulphur dioxide. The majority of these pollutants are emitted through human activities like burning fossil fuels, vehicle exhaust fumes and emissions from agriculture and industry.

What is a air pollution essay?
Essay on Air Pollution– Earlier the air we breathe in use to be pure and fresh. But, due to increasing industrialization and concentration of poisonous gases in the environment the air is getting more and more toxic day by day. Also, these gases are the cause of many respiratory and other diseases.
What is air pollution causes and effects?
“Burning fossil fuels releases gases and chemicals into the air.” And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth’s temperature,” Walke says.
Why air pollution is a problem?
Air pollution causes damage to crops, animals, forests, and bodies of water. It also contributes to the depletion of the ozone layer, which protects the Earth from the sun’s UV rays. Another negative effect of air pollution is the formation of acid rain, which harms trees, soils, rivers, and wildlife.
What are the natural causes of air pollution?
There are natural processes that create air pollution— such as sulfur and chlorine gases from volcanic activity, smoke and ash from wildfires, dust storms, and biological decay — but most pollution enters the air from human-made (anthropogenic) sources.
