How is ozone produced in the upper atmosphere
WebAs was already mentioned, ozone that occurs in the upper reaches of the atmosphere interacts with ultraviolet radiation coming from the sun. This interaction keeps most of that UV light from hitting the surface of the Earth, where it would cause serious problems for the plants and animals living there. Web14 feb. 2024 · In the lower atmosphere (the troposphere) near the Earth’s surface, ozone is created by chemical reactions between air pollutants from vehicle exhaust, gasoline vapors, and other emissions.

WebHow ground level ozone is formed in the air. UCAR/L.S. Gardiner. In the stratosphere, ozone molecules play an important role - absorbing ultraviolet radiation from the Sun and shielding Earth from dangerous rays.But in the troposphere, near ground-level, ozone molecules are both air pollutants, threatening the health of living things, and greenhouse … WebAlthough ozone is present in small concentrations throughout the atmosphere, most (around 90%) exists in the stratosphere, a layer 10 to 50 kilometres above the Earth’s surface. The ozone layer filters out most of the sun's harmful UV radiation and is therefore crucial to life on Earth. Ozone depletion
WebWhen ozone is produced by solar UV radiation in the tropics, it is done so by circulation lifting ozone-poor air out of the troposphere and into the stratosphere where the sun photolyzes oxygen molecules and turns them into ozone. Then, the ozone-rich air is carried to higher latitudes and drops into lower layers of the atmosphere Ozone Depletion Web22 nov. 2024 · The stratosphere increases in warmth with elevation because ozone gases in the upper layers absorb intense ultraviolet radiation from the sun. Ozone is only a trace gas in the atmosphere—only about three molecules for every 10 million molecules of air. But it does a very important job.
Web25 jul. 2024 · Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2).

Web7 jan. 2024 · The process of the ozone layer filtering UV radiation is as follows: (1) Gaseous oxygen molecules (O 2) are photolyzed (split), yielding two oxygen atoms. This is a slow process. (2) Ozone and oxygen atoms are continuously being interconverted as solar UV breaks O 3 into O 2 and a single oxygen atom (O).
