The problem of ozone hole is mainly related to the decline of which atmospheric element?
Answer and explanation
Correct answer: Stratospheric ozone
The governing concept is depletion of stratospheric ozone, especially in the polar stratosphere. Ozone molecules absorb much of the Sun’s harmful ultraviolet-B radiation, so a substantial reduction increases the amount of UV reaching Earth’s surface. The ozone hole does not mean that all atmospheric ozone has vanished. Option A is therefore correct; nitrogen and argon are major background gases, while sea salt is an aerosol, not the depleted atmospheric element in this issue.
