- What is Ozone? - US EPA
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 amount of harmful UV radiation reaching the Earth's surface
- Ozone - American Lung Association
Ozone (also called smog) is one of the most dangerous and widespread pollutants in the U S It may be hard to imagine that pollution could be invisible, but ozone begins that way As ozone concentrates and mixes with other pollutants, we often call it by its older, more common name—smog
- Ozone | Definition, Properties, Air Pollution, Importance, Structure . . .
Ozone is an irritating pale blue gas that is explosive and toxic, even at low concentrations It occurs naturally in small amounts in Earth’s stratosphere, where it absorbs solar ultraviolet radiation, which otherwise could cause severe damage to living organisms on Earth’s surface
- NASA Ozone Watch: Latest status of ozone
View the latest status of the ozone layer over the Antarctic, with a focus on the ozone hole Satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone Click any map image to bring up a new page with a high-resolution image
- Q1 What is ozone, how is it formed, and where is it in the atmosphere?
The word ozone is derived from the Greek word óζειν (ozein), meaning “to smell ” Ozone has a pungent odor that allows it to be detected even at very low amounts Ozone reacts rapidly with many chemical compounds and is explosive in concentrated amounts
- Ozone - New World Encyclopedia
Ozone (molecular formula O 3) is a minor constituent of the Earth's atmosphere, but its effects are highly significant It is chemically very reactive and is involved in reactions that drive many of the chemical changes that occur in the atmosphere by day and by night

What is ozone and where is it in the atmosphere? 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)
- What is Ozone? | California Air Resources Board
Ozone is formed in the atmosphere through chemical reactions between pollutants emitted from vehicles, factories and other industrial sources, fossil fuels, combustion, consumer products, evaporation of paints, and many other sources
