Question

Quizplus · Accepted Answer

The ozone layer in the Earth's atmosphere absorbs most of the ultraviolet radiation that comes from the sun, preventing it from reaching the Earth's surface. This is why the depletion of the ozone layer is a major concern, as it can lead to increased levels of ultraviolet radiation reaching us on the Earth's surface. The other options listed do not play as significant a role in absorbing ultraviolet radiation.
