Michael Treacy 3/3/2010 Pd. 3 Ozone Hole @ TD 1. What is the Ozone and why do we need it in our atmosphere to have a healthier planet? The Ozone is the Gas O3. This gas is located in the Stratosphere and absorbs UV Rays. We need the ozone in our atmosphere because it absorbs 98% of the UV Rays. Without the ozone to filter all these UV Rays many animals would have medical / health problems. 2. Describe how the ozone protects us. The ozone protects us by filtering out and absorbing most of the UV Rays before they reach the earth. Most of the Rays are biologically harmful and know to damage tissues and cells. 3. How is a chlorine atom harmful to the ozone in the stratosphere?

The Difference Between Global Warming and Ozone Depletion 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: Infrared heat enters but is trapped by the chemicals when it tries to escape. The chemicals act like a blanket. CO2 CH4 NOx CFCs H2O Global Warming vs. Ozone Depletion: Causes Ozone Depletion: Propellants (hairspray), Air Conditioners, some manufacturing. Chemicals react with UV protecting ozone in the stratosphere. CFCs CCl4 CF4 Ozone is good up high but bad nearby Global Warming vs. Ozone Depletion: Environmental Effects and Human Health: GLOBAL WARMING
