Question

Quizplus · Accepted Answer

The layer of gas that protects the earth from excessive ultraviolet radiation from the sun is known as ozone. Ozone is a form of oxygen that exists as a thin layer in the atmosphere, specifically in the stratosphere, and absorbs much of the sun's harmful ultraviolet radiation before it can reach the earth's surface. Carbon dioxide and methane are greenhouse gases that contribute to climate change, while oxygen is essential for human and animal respiration but does not play a direct role in protecting the earth from UV radiation.
