Ozone ( / ˈoʊzoʊn /) (or trioxygen) is an inorganic molecule with the chemical formula O3. 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, breaking down in the lower atmosphere to O ( dioxygen ).
Apr 17, 2024 · Ozone (O 3) is a gas molecule composed of three oxygen atoms. Ozone is good up high, bad nearby. The ozone layer found high in the upper atmosphere shields us from much of the sun's ultraviolet radiation. However, ozone air pollution at ground level where we can breathe it causes serious health problems.
Jul 11, 2023 · 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.
- Are High Ambient Ozone Concentrations Found only in Heavily Urbanized areas?Many people mistakenly believe that tropospheric ozone concentrations are high only in major urban areas, but high ambient ozone concentrations can...
- How Does Atmospheric Ozone Affect Human Health?Ozone has two properties of interest to human health. First, it absorbs UV light, reducing human exposure to harmful UV radiation that causes skin...
May 16, 2024 · 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.

Feb 14, 2023 · What is Ozone? 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.
Apr 25, 2024 · Ozone layer, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules. Approximately 90 percent of the atmosphere’s ozone occurs from 10–18 km (6–11 miles) to about 50 km (about 30 miles) above Earth’s surface.
