A. The thickness of ozone layer is measured in - Dobson units (IV): This unit is used to measure the thickness of the ozone layer in the atmosphere.
B. The degradation of ozone layer- CFCs (I): Chlorofluorocarbons are the primary chemicals responsible for the depletion of the ozone layer.
C.The region where good ozone is found- Stratosphere (V): This is the layer of the atmosphere where "good" ozone is found, forming the ozone layer that protects the Earth from harmful ultraviolet (UV) radiation.
D. The unit to measure the intensity of sound- dB (decibels) (II): Decibels are the unit used to measure the intensity of sound.
