WHAT IS GREENHOUSE EFFECTA 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

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

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

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

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
