Correct option is D
The correct answer is (d) SO₂
Explanation:
. Global warming is caused mainly by greenhouse gases that trap heat in the Earth’s atmosphere.
. Carbon dioxide (CO₂), water vapour and nitrous oxide (N₂O) are major greenhouse gases.
. Sulphur dioxide (SO₂) is not a greenhouse gas and does not trap heat.
. SO₂ generally causes cooling by forming sulphate aerosols that reflect sunlight back into space.
. Therefore, SO₂ is not responsible for global warming.
Information Booster:
. Major greenhouse gases include CO₂, CH₄, N₂O, water vapour and CFCs.
. Human activities like burning fossil fuels increase greenhouse gas concentration.
Additional Knowledge:
CO₂ (Option a)
. Major contributor to global warming due to fossil fuel combustion.
Water vapour (Option b)
. Most abundant greenhouse gas; amplifies warming through feedback mechanism.
N₂O (Option c)
. Potent greenhouse gas released from fertilizers and industrial processes.
