What Causes Air Pollution?

This interactive article created by NASA Climate Kids answers the question: What causes air pollution? Children will learn that 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 (Source).
