The ozone layer protects life on earth by absorbing harmful ultraviolet radiation. the ozone layer is located between 17 kilometers and 35 kilometers above earth's surface in which atmosphere temperature zone?

(1) troposphere
(2) stratosphere
(3) mesosphere
(4) thermosphere

The correct answer is (2) - Stratosphere. Ozone is found in the stratosphere , a layer beginning between 6 and 10 miles above the earth's surface and extends upward to about 30 mile above the surface of he earth. The ozone that is found in the stratosphere absorbs most of he harmful ultraviolet sunlight and is thus called the "good ozone" Ozone is also found in the lower region of the atmosphere known as the troposphere. But the ozone here strongly reacts with molecules causing toxicity in plants. The ozone is therefore termed as "bad ozone."
