PPT-Global Warming Vs. Ozone Depletion

Venn Diagram CompareContrast GLOBAL WARMING OZONE DEPLETION Both harm the environment Both caused by chemicals released by human activities Caused by high levels of CO. Many people consider that Global Warming is the greatest environmental threat of the 21. st. Century. . However, during the 80s and early 90s scientists argued about the causes and effects of global warming. . DEPLETION. What is Ozone?. Two different layers in the atmosphere:. . Troposphere. Stratosphere. . What is ozone layer?. Ozone layer is a thin, fragile shield that contains relatively high concentrations of ozone.. 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 Matthew and saeb . What is global warming. Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO2 annually. Created and presented by Brandi graham. What is global warming and why is it happening? . Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate. 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.

Tropospheric. ozone depletion event (ODE) usually happens in spring,. . polar. . region.. ODE looks strongly related to the amount of atmospheric bromine chemistry based on the heterogeneous reaction (Barrie et al., 1988). Ozone Depletion(Chapter 25). Ozone Properties. 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. He estimated that Nitrogen oxides derived depletion of 10-90%. . Nobody at that time knew what the stratospheres natural concentration of Nitrogen oxide was, but even if you didn't know how much Nitrogen oxide there was, it's difficult to calculate its effect.. Global warming is a key threat to biodiversity but few researchers have assessed the magnitude2climates calculated changes in habitatnumerous uncertainties in this approach we undertook a sensitivity Global warming is when the earth heats up and the temperature increases. More recently, the temperatures have been rising, causing more dangers for people, animals, plants and our environment.. The Greenhouse Effect. Nitrous . Oxide (N. 2.
