Mark the statements as true (T) or false (F).
i) The thickness of the ozone is measured in the terms of dB.
ii) CFCs produce active chlorine in presence of UV radiation.
iii) Water logging is the only problem in the wake of green revolution.
Answer & explanation
Correct answer: option 2
The thickness of the ozone is measured in the terms of Dobson units (DU).
CFCs produce active chlorine in presence of UV radiation. These destroy ozone, converting it into oxygen.
Water logging and soil salinity are the problems in the wake of green revolution.
