Reactive ozone gases
Did you know?
Ozone (O3) is a highly reactive gas composed of three oxygen atoms. It is both a natural and a man-made product that occurs in the Earth's upper atmosphere (the stratosphere) and lower atmosphere (the troposphere). Depending on where it is in the atmosphere, ozone affects life on Earth in either good or bad … See more Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The \"ozone layer,\" approximately 6 through 30 miles above the Earth's surface, reduces the … See more Tropospheric or ground-level ozone what we breathe is formed primarily from photochemical reactions between two major classes of air … See more Figure 1: U.S. counties with high ozone concentrations in 2009.
