Question

Quizplus · Accepted Answer

Ozone is a gas in the stratosphere that absorbs and scatters harmful ultraviolet (UV) radiation from the sun. Without the ozone layer, life on Earth would be exposed to dangerous levels of UV radiation, which can cause skin cancer, cataracts, and other health problems. Hydrogen, argon, and nitrogen do not have the same protective properties as ozone.
