. Global Warming

5. The sun sends out energy
as heat and light. This
energy comes to our earth
during the day time.
Some of the sun’s rays get
‘trapped’ in the atmosphere.
Some of them get reflected
back into space.
The ones which get through the
atmosphere warm the earth up.

11. Greenhouse Gases
• Carbon Dioxide (CO2)
– Source: Fossil fuel burning, deforestation
 Average atmospheric residence time: 500 year

12. Methane (CH4)
Source: Rice cultivation, cattle & sheep ranching, fossil fuel, waste dumps, mining
Average atmospheric residence time: 7-10 years
Nitrous oxide (N2O)
Source: Industry and agriculture (fertilizers)
Average atmospheric residence time: 140-190 years

13. Ozone
‫اوزون‬

14. chlorofluorocarbon (CFC)
Chlorofluorocarbons (CFCs) are
nontoxic, nonflammable chemicals
containing atoms of carbon,
chlorine, and fluorine. They are
used in the manufacture of aerosol
sprays, packing materials, and as
refrigerants.

18. VOLCANOS
‫آتشفشانونه‬
• Gases which emit from a
Volcano:
a. carbon dioxide,
b. sulfur dioxide,
c. hydrogen sulfide and
d. hydrogen halides

19. Land Slides

a. Deforestation
b. Dust (air pollution)

20. Industries
‫فابریکي‬
•Industries Produce
lots of CO2 to the
Earth’s Atmosphere.

21. Transportation
•Vehicles and
Airplanes can also
produce CO2 , CO,
SO2 etc gases.

22. Deforestation
‫کول‬ ‫قطع‬ ‫دځنګلونو‬
•Tress and plants
produce Oxygen
and Precipitate
CO2.

23. Mining Process ‫معدن‬
‫کاري‬
-
•Air pollution from
coal mines is mainly
due to emissions of
particulate matter and
gases including
methane (CH4),
SO2, and (NOx), as
well as (CO).

24. House Holds

25. Around 3 billion people cook and heat
their homes using solid fuels (i.e. wood,
charcoal, coal, dung, crop wastes) on
open fires or traditional stoves. Which
produce pollutants such as fine
