A) green house effect
B) solar effect
C) ozone layer effect
D) radioactive effect
Correct Answer: A
Solution :
The sunlight penetrating the atmosphere warms the earths surface. The earth surface reradiates the heat (infrared wavelengths) to the atmosphere and some escapes into space. Green-house gases and water vapour absorb some infrared wavelengths and reradiate part of them towards the earth. When green-house gases build up in the atmosphere, more heat is trapped near the earths surface. Ocean surface temperature rise, more water vapour enters the atmosphere and the earths surface temperature increases ie, called greenhouse effect. The main gases responsible for greenhouse effect are,\[C{{O}_{2}},C{{H}_{4}},CFCs,{{O}_{3}}\]etc.You need to login to perform this action.
