he severe depletion of stratospheric ozone in late winter: Transcript

Q27 T and early spring in the Antarctic is known as the 147ozone hole148 see Q11 e ozone hole rst appeared over Antarc tica because atmospheric and chemical conditions unique to this. Stratospheric ozone: the natural cycle Produced in stratosphere by dissociation of oxygen atoms exposed to short-wave radiation Reaction accounts for most of adsorption of ultraviolet sunlight () as w Ozone Depletion. Quick recap…. ". The ozone layer. " refers to the ozone within stratosphere. over 90% of the earth's ozone resides. Ozone is an irritating, corrosive, colourless gas with a smell. O. Layer. Depletion. “. Life’s Support System Depletion. ”. Outline of Presentation. What is the Ozone layer?. How is ozone created and destroyed?. What is the Ozone hole?. What are the causes of Ozone Depletion?. by . David Gray. Scientific use. Background ozone. ozone present through natural or nonlocal sources. currently ranges from 20-45 ppb in North . America. Rising background ozone could mean non-attainment for much of North America. Venn Diagram. Compare/Contrast. GLOBAL WARMING. OZONE DEPLETION. Both harm the environment. Both caused by chemicals released by human activities. Caused by high . . levels of . CO. Tuesday, January 5. th. , 2015. Good up high, bad nearby. Troposphere:.

Foreman Room 102. 1. Global Warming and Ozone Depletion take place in two different layers of the atmosphere: . Global Warming. Ozone . Depletion. Global Warming vs. Ozone Depletion: Causes. Global Warming: cars, factories, rice farming, landfills: . Ozone produced from the interaction of hydrocarbons and oxides in the presence of sunlight. At ground level, ozone is a pollutant; in the upper atmosphere it protects earth from excess radiation from sun. Observations, processes, and impact on climate. Stefanie .

Ozone (O. 3. ). is a triatomic form of oxygen found mostly in the lower half of the atmosphere. Highly reactive strong oxidant. Tropospheric pollutant produced by photochemical reactions. The . ozone layer or ozone shield . is a region of Earth's stratosphere that absorbs most of the Sun's UV radiation. . It contains high concentration of ozone (O3).. It is a pale blue gas at room temperature.. found?. The . ozone layer . is the layer of the atmosphere at an altitude of 15 to 40 km (stratosphere) . What is Ozone?. Ozone. . is a molecule made of three oxygen atoms. What is the function of the ozone layer. S. Weber. 1. , R. Ruhnke. 1. , P. Braesicke. 1. , C. Scharun. 1. 1. Institute of Meteorology . and Climate Research. Significance of stratospheric ozone (O. 3. ):. Plays a critical role in absorbing ultraviolet (UV) radiation emitted by the sun.
