AIR POLLUTION
When the ___r is dirty it has become polluted. Air pollution is made up of______s, dust,
odors, particles, smoke, fumes, and other substances which can be harmful to _______s, animals,
plants, and all living organisms. The air is contaminated and unclean.
Air pollution affects the Earth's _________e. The atmosphere of the Earth is like a ______t
of air which protects all life. Without the atmosphere, life would not exist. The atmosphere protects
living organisms from the _____t of the Sun during the day, and at night it prevents the warm air
from escaping. Basically, the atmosphere helps keep the living things on _____h from burning up
or freezing.
The _______n in the air, though, may affect this 'blanket' and becomes harmful to life on
Earth. The substances in the air causing the dirty air are called ________s. Some examples of
pollutants may include gases called carbon _________e, nitrogen _______e, hydrocarbons, and
others. There may also be sand, _____t particles, and other substances that evaporate and become
pollutants.
A ________y pollutant is one that is directly released into the air causing pollution. An
example is carbon monoxide, which comes from cars and trucks on the road. A second primary
pollutant is sulfur dioxide, which comes from the burning of _____l.
A secondary pollutant is a substance or substances mix together in the air due to a
_________l reaction. When these substances mix together, the air pollution is much more
dangerous and harmful to organisms. An example is ___________l ______g.
It is difficult to avoid the pollution in the air since it is the place where people get the
________n to breathe and live. Pollution can travel with the wind from one place to another and
spread over a large number of miles.
Pollution can be caused by humans or it can also occur naturally. For example, _______l
pollution may come from ________s, forest fires, wind storms, pollen in the air, and other sources
in nature.
The three main causes of pollution by humans includes the release of smoke and fumes from
manufacturing plants and various ________s. Power plants release carbon monoxide and furnaces
that burn waste are two examples of __________e pollution. _________e refineries also release
dangerous chemicals in the air called hydrocarbons. The second cause is the burning of fossil fuels
such as from cars, trucks, trains, airplanes. This type of pollution occurs often because people rely
on __________n every day. Another main cause of pollution is from household and farming
chemicals. On farms crop dusting may pollute the air, homes may be sprayed with chemical to kill
bugs or to help the grass grow.
There are several effects of air pollution including ____d rain, which is when rain is mixed
with the pollution in the air. This acid rain can cause harm to trees, animals, fish, and other living
organisms. It can cause problems with breathing and irritation to the eyes, nose, or throat.
Sometimes people can also get headaches or have allergic reactions. Long-term effects can include
lung cancer, heart disease and other health problems.
