The Destruction of The Ozone Layer
ozone layer. Concerns that increased UV radiation due to ozone depletion threatened life on Earth led to bans on the chemicals, and the latest evidence is that ozone depletion has slowed or stopped. Ozone in the Earth's stratosphere is created by ultraviolet light striking ordinary oxygen molecules containing two oxygen atoms (O2 splitting them into individual oxygen atoms (atomic oxygen the atomic oxygen then combines with unbroken O2 to create ozone,. "Variability in the speed of the BrewerDobson circulation as observed by Aura/MLS". "Climate Change and Knowledge Politics" (PDF). Protecting the Ozone Layer : Science and Strategy. Journal of Environmental Studies and Sciences. The band of UV closest to visible light, UV-A (315400 nm is hardly affected by ozone, and most of it reaches the ground.
The Destruction of Easters Bionetwork,
The ozone molecule is unstable (although, in the stratosphere, long-lived) and when ultraviolet light hits ozone it splits into a molecule of O2 and an individual atom of oxygen, a continuing process called the ozone -oxygen cycle. Chemically, this can be described as: O2 uv 2 O O O2 O3 About 90 percent of the ozone in the atmosphere is contained in the stratosphere. Further reading edit Science United Nations Environment Programme (2010). The reasons for this latitude and seasonal dependence are complicated, which involve in atmospheric circulation patterns as well as solar intensity. Stratospheric Ozone an Electronic Textbook. Compliance with international treaties that phased out the production and delivery of many ozone -depleting chemicals, combined with upper stratospheric cooling due to increased carbon dioxide, is thought to have contributed to the shrinking of the ozone holes over the poles and to slightly higher. " The Role of HFCs in Mitigating 21st Century Climate Change". 8 The Brewer-Dobson circulation moves the Russian Pogroms very slowly. 4 Contents Sources edit The photochemical mechanisms that give rise to the ozone layer were discovered by the British physicist Sydney Chapman in 1930.
