Ozone - Wikipedia Ozone ( ˈ oʊ z oʊ n ) (or trioxygen) is an inorganic molecule with the chemical formula O 3 It is a pale blue gas with a distinctively pungent smell It is an allotrope of oxygen that is much less stable than the diatomic allotrope O 2, breaking down in the lower atmosphere to O 2
What is Ozone? | US EPA - U. S. Environmental Protection Agency 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 ways
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
Department of Environmental Quality : Air Quality Today : Air Quality . . . Oregon’s index is based on three pollutants regulated by the federal Clean Air Act: ground-level ozone, particle pollution and nitrogen dioxide The highest of the AQI values for the individual pollutants becomes the AQI value for that day
Ozone | Definition, Properties, Air Pollution, Importance, Structure . . . Ozone is a triatomic allotrope of oxygen (a form of oxygen in which the molecule contains three atoms instead of two as in the common form) that accounts for the distinctive odor of the air after a thunderstorm or around electrical equipment
What Is Earth’s Ozone Layer and Why Is It Important? The ozone hole, though still present, began to stabilize And slowly, slowly, the shield began to mend The Ripple Effect: Ozone and Climate Interestingly, the story of the ozone layer has unexpected ties to climate change While ozone depletion and global warming are distinct problems, they intersect in fascinating ways
Q1 What is ozone, how is it formed, and where is it in the atmosphere? Ozone is a gas that is naturally present in our atmosphere Each ozone molecule contains three atoms of oxygen and is denoted chemically as O 3 Ozone is found primarily in two regions of the atmosphere About 10% of Earth’s ozone is in the troposphere, which extends from the surface to about 10–15 kilometers (6–9 miles) altitude
Nasa Ozone Watch: Ozone facts Ozone is a gas made up of three oxygen atoms (O 3) It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere) Ozone protects life on Earth from the Sun’s ultraviolet (UV) radiation
What Is Ozone? Definition and Facts - Science Notes and Projects Ozone is an inorganic oxygen molecule with the chemical formula O 3 It is a reactive allotrope of oxygen that also goes by the name trioxygen Ozone protects the planet from harmful ultraviolet radiation, yet is also acts as a pollutant near the Earth’s surface and carries health risks
