Which effect is most related to weakening of the ozone layer?
Answer and explanation
Correct answer: More ultraviolet radiation reaching Earth
The ozone layer is concentrated mainly in the stratosphere and absorbs a substantial part of the Sun’s harmful ultraviolet radiation, especially UV-B. When this layer is weakened, its protective absorption decreases, allowing more ultraviolet radiation to reach Earth’s surface. This can increase risks to living organisms. Hence option B is correct; the other effects do not follow from ozone depletion.
