प्रश्न
How is ozone formed in the higher level of atmosphere?
उत्तर
The ozone layer is continuously formed in the atmosphere because of the action of UV rays on molecular oxygen. The high-energy UV radiations break down O2 molecules present in upper layers of the atmosphere into nascent oxygen.
Then, this free oxygen atom combines with an oxygen molecule to form ozone.
