Web9 feb. 2024 · Ozone makes up roughly 0.00006% of the atmosphere and peak concentrations of it are present at 20 miles (32 km) above the surface, in an area known as the ozone layer, according to NASA. 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).
Web20 mei 2024 · Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and … WebAgain, notice that HOx (OH + HO2) is neither produced nor destroyed by this cycle, but merely acts as a catalyst for converting two molecules of ozone into three molecules of O2.The importance of this reaction is that it does not require free O atoms for the reaction. Two other reactions are important for OX loss in the upper stratosphere. The first one …
WebGround level ozone. Figure 1. Ozone (O 3) consists of 3 oxygen atoms bonded together. [1] While essential in the upper atmosphere, near the ground ozone causes breathing problems. Ground level ozone is a highly reactive secondary pollutant. This pollutant forms when primary pollutants, like hydrocarbons and nitrogen oxides, react with sunlight. Web1 apr. 2024 · Ozone depleting substances are man-made gases that destroy ozone once they reach the ozone layer. The ozone layer sits in the upper atmosphere and reduces the amount of harmful ultra violet radiation that reaches Earth from the sun. Ultraviolet radiation can have detrimental effects on both humans and the environment.
