1. WHAT IS GREENHOUSE EFFECT
A process by which thermal radiation from a planetary
surface is absorbed by atmospheric greenhouse
gases, and is re-radiated in all directions.
THIS IS A BOOKISH DEFINITION
WE CAN SAY THAT…..
Heating of Earth due to the presence of greenhouse
effect

GREENHOUSES GASES
RATIO

5. Greenhouse Gases

13%
6%
Carbon Di-Oxide
Nitrous Oxide
Methane
76%
FluoroCarbons

6. MAIN NON-GASEOUS CONTRIBUTOR TO
GREENHOUSE EFFECT
CLOUDS
As it absorbs & emit infrared radiation in the
environment…
It have an effect on radiative properties of the
atmosphere

7. MAIN SOURCES OF
GREENHOUSE GASES
 Burning of Fossil Fuels & Deforestation
 Livestock enteric fermentation & manure
management
 Use of Chlorofluorocarbons {CFCs} in
refrigeration systems
 Agricultural Activities, like use of fertilizers

8. EFFECTS OF GHG ON ECOSYSTEM
 Many species of plants & animals face the
danger of extinction
 Increase in salinity of freshwater will affect
species of freshwater fish & plants
 Movement among tectonic plates beneath
the Earth

9. BEST EXAMPLE FOR GREENHOUSE EFFECT
CAR PARKING IN SUNLIGHT
 Glass of cars lets the sunlight trap inside the
car’s body
 Glass prevents heat to escape
 Thus, car goes heat up
