प्रश्न
Which of the following statements is wrong?
विकल्प
Ozone is not responsible for green house effect.
Ozone can oxidise sulphur dioxide present in the atmosphere to sulphur trioxide.
Ozone hole is thinning of ozone layer present in stratosphere.
Ozone is produced in upper stratosphere by the action of UV rays on oxygen.
उत्तर
Ozone is not responsible for green house effect.
Explanation:
Since O3 is responsible for the greenhouse effect, its contribution is about 8% to 10%. About 75% of the solar energy reaching the earth is absorbed by the earth’s surface, which increases its temperature. The rest of the heat radiates back to the atmosphere while some of the heat is trapped by gases such as carbon dioxide, methane, ozone, chlorofluorocarbon compounds (CFCs) and water vapour in the atmosphere. Thus, they add to the heating of the atmosphere. This is the reason behind global warming.
