Why is even the small amount of ozone considered a major element of atmospheric protection?

Answer and explanation

Correct answer: Because it absorbs a large part of ultraviolet radiation

The correct answer is A: ozone absorbs a large part of the Sun’s harmful ultraviolet radiation. Most protective ozone is concentrated in the stratosphere, where its molecules absorb important ultraviolet wavelengths before they reach the surface. This filtering reduces the amount of biologically damaging radiation received by living organisms. The protective importance of a substance depends on what it does, not only on how much of it is present. B is wrong because clouds form mainly through water vapour and condensation nuclei. C is wrong because ozone does not create rivers. D is wrong because ozone is not responsible for evaporating sea salt. Memory cue: a thin ozone shield filters harmful UV radiation.
