Air ... like really whats that ... All around the earth there is a thick blanket of air called the atmosphere or air ... or short

Like other gases does not have a fixed shape It spreads out to fill any available space so nothing is really empty.

Air pollution ... ever since people first gathered in settlements there has been pollution.

Pollution usually refers to the presence of substances that are either present

in the environment where it doesn't belong or at levels greater than it should be.

Air pollution is caused by any undesirable substance which enters the atmosphere air pollution is a major problem in modern society

Even though air pollution is usually a greater problem in cities, pollutants

contaminate air everywhere these substances include various gases and

tiny particles, or particulates that can harm human health and damage the

environment.

They may be gases, liquids, or solids. Many pollutants are

given off into the air as a result of human behavior. Pollution occurs on different levels: personal, national, and global ... some pollutants come from natural sources.

Forest fires emit particulates, gases, and VOCs (substances that vaporize into the atmosphere)

Ultra-fine dust particles created by soil erosion when water and weather loosen layers of soil, increase airborne particulate levels.

Volcanoes spew out sulfur dioxide and large amounts of pulverized lava rock known as volcanic ash .... the major types of air pollution are: Gaseous pollutants: A different mix of vapors and gaseous air pollutants is found in outdoor and indoor environments.

The most common gaseous pollutants are carbon dioxide, carbon monoxide, hydrocarbons, nitrogen oxides, sulfur oxides and ozone.

A number of sources produce these chemical compounds but the major man-made source is the burning of fossil fuel. Indoor air pollution is caused by cigarette smoking, the use of

certain construction materials, cleaning products, and home furnishings.

Outdoor gaseous pollutants come from volcanoes, fires, and industry, and

in some areas may be substantial.

The most commonly recognized type of

air pollution is smog. Smog generally refers to a condition caused by the
