Why does indirect risk to human health increase when the ozone layer weakens?
Answer and explanation
Correct answer: More ultraviolet radiation can reach Earth
The governing concept is stratospheric ozone absorption of ultraviolet radiation. The ozone layer normally absorbs much of the Sun’s harmful UV-B and some UV-C radiation. If it becomes thinner, more UV can reach Earth’s surface, increasing risks such as sunburn, skin damage, eye injury, and harm to some organisms. Thus option A is correct; the other choices describe processes that do not follow from ozone depletion.
