Concept explainers
(a)
Interpretation:
Near to which cities the air hazardous to one or more groups has to be identified.
Concept introduction:
Stratosphere:
It is found below the mesosphere layer in which the concentration of ozone and other gases are high. The increasing temperature for this layer with respect to increasing height is due to the presence of high concentration of ozone and other gases in it.
The increased temperature is due to the response of UV radiation from sun and hence ozone is formed due to this reaction and the use of ozone is that it prevents the UV radiation from the sun which is actually harmful.
Chlorofluorocarbon (CFC): They are compounds that contain only carbon, fluorine and chlorine with it. They are gases can be easily liquefied, have little ability to react readily, are non-poisonous and do not catch fire easily.
Nitrogen oxides: They are binary compound that contains only oxygen and nitrogen with them.
Ozone: It is an allotrope of oxygen with chemical formula
Ozone layer depletion is the destruction process of ozone layer by various chemicals mainly chlorofluorocarbons (CFC).
(b)
Interpretation:
Time at which the ozone level peak has to be identified.

(c)
Interpretation:
Moderate levels of ozone whether exist in the absence of sunlight has to be identified.
