The two gases making highest relative contribution to the greenhouse effect are
1 \(\mathrm{CO}_{2}\) and \(\mathrm{CH}_{4}\)
2 \(\mathrm{CH}_{4}\) and \(\mathrm{NH}_{2}\)
3 \(\mathrm{CFC}\) and \(\mathrm{N}_{2} \mathrm{O}\)
4 \(\mathrm{CO}_{2}\) and \(\mathrm{NO}_{2}\)
Explanation:
Greenhouse effect is a phenomenon in which some gases present in the atmosphere keeps the earth warm and these gases are Chloro fluoro carbon \({\rm{(CFC)}}\), Carbon dioxide \(\left(\mathrm{CO}_{2}\right)\), Methane \(\left(\mathrm{CH}_{4}\right)\) and Nitrogen oxide \(\left(\mathrm{N}_{2} \mathrm{O}\right)\)

Without greenhouse effect the average temperature at surface of Earth would be how much? What is present average temperature of earth?
1 \(-18^{\circ} \mathrm{C}\) and \(25^{\circ} \mathrm{C}\) respectively.
2 \(-18^{\circ} \mathrm{C}\) and \(27^{\circ} \mathrm{C}\) respectively.
3 \(-28^{\circ} \mathrm{C}\) and \(15^{\circ} \mathrm{C}\) respectively.
4 \(-18^{\circ} \mathrm{C}\) and \(15^{\circ} \mathrm{C}\) respectively.
Explanation:
Without greenhouse effect the average temperature at surface of Earth would have been a chilly \(-18^{\circ} \mathrm{C}\) rather than the present average of \(15^{\circ} \mathrm{C}\).

Assertion : Methane component of greenhouse gases contributing to globalwarming is about \(20 \%\). Reason : Introduction of multipoint fuelinjectionenginesinautomobile has decreasedmethane content in the exhausts.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
The formation of the ozone layer is also caused by photo dissociation. Ozone in the Earth's stratosphere is created by ultraviolet light striking oxygen molecules containing two oxygen atoms \(\left(\mathrm{O}_{2}\right)\), splitting them into individual oxygen atoms (atomic oxygen).
