Answer

Explanation

Greenhouse effect is a process by which thermal radiations from a planetary surface, (e.g., earth) are absorbed by atmospheric greenhouse gases and are re-radiated in all the directions causing an increase in the overall temperature of the planet (earth). By percentage contribution to the greenhouse effect on the earth the four major gases are
(i) Water vapour `36-70%` (ii) Carbon dioxide `9-26%`
(iii) methane `4-9%` (iv) Ozone `3-7%`
Other greenhouse gases are nitrois oxide `(N_(2)O)` and CFC, i.e., chloroflouro carbons.
