This document discusses various types of atmospheric pollution. It defines air pollution as the presence of any harmful gases in the atmosphere. It describes acid rain as occurring when carbon dioxide mixes with water vapor to form carbonic acid, and explains that increased CO2 levels lead to more intense acid rain, which can harm health. The document also notes that greenhouse gases like carbon dioxide and methane regulate temperature by trapping heat, and that global warming is defined as the increase in the average temperature near Earth's surface, which is caused by factors like increased CO2, methane, vehicles, industry, deforestation, and population growth. Finally, it states that ozone depletion is caused by CFCs released from sprays and paints, leading
4. The presence of any gas
becomes threat to health
whether in higher or
smaller amounts and if
new gases are added to
the atmosphere, it is
called air pollution
5. ACID RAIN
The carbon dioxide in the air
mixes with the water vapour
and carbonic acid is formed .
When the quantity of carbon
dioxide in the atmosphere
increases , the intensity of the
acid rain also increases . It
causes problems for the
kidneys , weakening of bones
and affects the growth .
6. GREENHOUSE EFFECTS
The gases like carbon dioxide
and Methane, and water
vapour found in the
atmosphere play an important
role in the regulating the
temperature . These are green
house gases .The glass
houses used in cold regions
to grow plants are known as
green houses.
7. GLOBAL WARMING
The increase in the
average temperature
near the surface of
the earth is global
warming
8. CAUSES OF GLOBAL
WARMING
Carbon dioxide and
Methane.
Increase in the number of
vehicles.
Greenhouse gases.
Industrialization.
Deforestation.
Increase the population.
9. OZONE DEPLETION
The sprays, paints and other
articles we use release CFC
and these gases are agent
which causes destruction of
the ozone layer .The
depletion caused to the
ozone layer is called the
ozone hole.
10. PROBLEMS CAUSED BY THE
OZONE DEPLETION
•Change in climate .
•Destruction to agriculture
and forest.
•Increase in the incident of
skin cancer.
