The ozone layer is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet (UV) radiation. Ozone (O\u2083) concentration is highest in the lower portion of the stratosphere, from about 15 to 35 kilometers above Earth’s surface, although it is present in small quantities throughout the atmosphere. Ozone depletion, primarily caused by human-produced ozone-depleting substances like chlorofluorocarbons (CFCs), is a significant phenomenon occurring within the stratosphere.
\n<\/section>\n
The Earth’s atmosphere is divided into several layers: Troposphere (lowest), Stratosphere, Mesosphere, Thermosphere, and Exosphere (highest). The ozone layer resides primarily within the stratosphere.
\n<\/section>\n
While the stratosphere is where beneficial ozone is found and depleted, ozone is also present in the troposphere. Tropospheric ozone is a key component of smog and is considered a harmful air pollutant and a greenhouse gas, but it does not form a “layer” in the same way as stratospheric ozone and is not where the major depletion phenomenon occurs.
