32. Global warming is mainly due to accumulation of A.Oxides of nitrogen B.Oxides of sulphur C.Carbon dioxide D.Carbon monoxide
Answer: Option C Solution: Global Warming refers to average increase in the earth’s temperature due to increase in pollution which results in greenhouse effect which in turn leads to climate change. Global warming may lead to rise in the sea level due to melting of glaciers, shrinkage of forests, changes in the rainfall pattern and 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 the outer space.
