Answer 2

Answer:

1. Gases that lead to air pollution include carbon, nitrogen and sulfur oxides. While some of these gases occur naturally, like carbon dioxide in the expulsion of air from the lungs, the serious polluters come from the burning of fossil fuels: coal, oil and natural gas    

2.  There are four main types of air pollution sources:

mobile sources – such as cars, buses, planes, trucks, and trains.

stationary sources – such as power plants, oil refineries, industrial facilities, and factories.

area sources – such as agricultural areas, cities, and wood burning fireplaces.                                                                                                               3.
