  • 1. WHAT IS GREENHOUSE EFFECTA process by which thermal radiation from a planetarysurface is absorbed by atmospheric greenhousegases, and is re-radiated in all directions. THIS IS A BOOKISH DEFINITION WE CAN SAY THAT…..Heating of Earth due to the presence of greenhouseeffect
  • 2. HOW DOES THEGREENHOUSE EFFECT HAPPENS
  • 3. GREENHOUSES GASES R E INFRARED R RADIATIONS A D I AA TB ES DORBE LOWERS THED ATMOSPHERE TO WARM
  • 4. SOME OF THEGREENHOUSES GASES RATIO
  • 5. Greenhouse Gases 5% 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 OFGREENHOUSE 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
