Global warming is mainly due to the accumulation of
(1) Oxides of Nitrogen
(2) Oxides of sulfur
(3) Carbon dioxide
(4) Carbon monoxide
Answer: (3) Global Warming refers to an average increase in the Earth’s temperature due to an increase in pollution, which results in the greenhouse effect, which in turn leads to climate change. Global warming may lead to a rise in the sea level due to the melting of glaciers, shrinkage of forests, changes in the rainfall pattern, and a wide range of impacts on plants and humans. The greenhouse gases such as carbon dioxide accumulate into the atmosphere and trap heat that would normally exit into outer space.
