Answer 2

Answer:

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

natural sources – such as wind-blown dust, wildfires, and volcanoes

Graphic of Air pollution pathways: mobile, stationary, area, and natural.

Mobile, stationary, area, and natural sources all emit pollution into the air.

Mobile sources account for more than half of all the air pollution in the United States and the primary mobile source of air pollution is the automobile, according to the Environmental Protection Agency. Stationary sources, like power plants, emit large amounts of pollution from a single location, these are also known as point sources of pollution. Area sources are made up of lots of smaller pollution sources that aren't a big deal by themselves but when considered as a group can be. Natural sources can sometimes be significant but do not usually create ongoing air pollution problems like the other source types can.
