The ozone layer in the upper atmosphere absorbs dangerous ultraviolet radiation from the sun.

Question

Quizplus · Accepted Answer

The ozone layer does indeed absorb dangerous ultraviolet radiation from the sun, which helps protect life on Earth from the harmful effects of this radiation. Ozone is a molecule made up of three oxygen atoms (O3), and it is most abundant in a layer located about 10 to 50 kilometers (6 to 30 miles) above the Earth's surface, known as the "ozone layer". This layer helps to block out most of the sun's harmful UV radiation, which can cause skin cancer, cataracts, and other health problems in humans, as well as harm crops and other living organisms. However, human activities have led to the depletion of the ozone layer through the release of certain chemicals, such as chlorofluorocarbons (CFCs), which break down ozone molecules. This is a serious environmental issue that has been addressed through international agreements like the Montreal Protocol, which aims to phase out the use of ozone-depleting substances.
