How is ozone formed in the higher levels of the atmosphere ? “Damage to the ozone layer is a cause of concern.” Justify this statement.
Solution
*UV radiations act on the oxygen molecule (O2) and then split oxygen molecule into free (nascent) oxygen.
*These free oxygen atoms combine with oxygen molecule (O2) to form ozone (O3)
Alternate answer:
O2 $\xrightarrow{\text{UV}}$ O + O
O + O2 → O3
Damage to ozone layer :
*UV radiations reach the Earth and cause harmful effects like skin cancer in human beings.
