Exam questions often ask which gas is the main cause of a problem (chlorofluorocarbons for ozone depletion, and sulphur and nitrogen oxides for acid rain), which gas leaked in the Bhopal gas tragedy (methyl isocyanate), and which disease is caused by a pollutant, such as Minamata disease from mercury. Know the major greenhouse gases. Practise the pollution and climate change questions below, written in the style of the general awareness sections of exams such as SSC, banking, railways, CUET GAT, MAH CET and CLAT. Each question comes with a detailed explanation that adds related facts, so every question helps you revise more than one point.
