Greenhouse effect = Global warming cause and effect law is true!
- Solar radiation warm the earth surface
- Heat energy is reflected into atmosphere
- When there is too much CO2 in atmosphere it form a layer.
- Heat is radiated back to earth . Increasing the temperature of earth
Greenhouse
effect is further worsen by combustion of fossil fuel in motor vehicle , and in
power station, to generate electricity and industry. These three activity burnt
fossil fuel.
These
activity produce large quantity of co2
As
the world population strive for higher standard of living, there will increase
use of cfc in product such as aerosol , refrigerator, air conditioner and
during of production of packaging material such as styrofoam .
The
increase in the concentration of these greenhouse gases (co2,NO) lead to
increase temperature on earth because these gases trapped and reflected heat
back to the earth.
Green
house effect can change the local and global climate causing the shift in
vegetation.
This
merely to extinction of certain species of organism which are unable to adapt
to changing in environment.
Greenhouse
effect are similar to global warming therefore flashflood occur.
