SCI 207 Quiz Week 2 Quiz – correct response is marked with asterisk (*) 1. Question: A decrease in “food miles” will most likely increase the environmental impact of any given food. True False * Question 2. Which of the following statements about ground water is not true‚ according to your text? Underground aquifers hold approximately 99% of all the liquid fresh water. More than 75% of underground water has a replenishment time of centuries or more‚ making it non-renewable. Increased water

Chapter 13 Vocab Chlorofluorocarbons (CFCs): Synthetic organic compounds first created in the 1950s and used primarily as refrigerants and as propellants. The role of CFCs in the destruction of the ozone layer led to the signing of an international agreement (the Montreal Protocol).

division accounted for two percent of Du Pont’s revenue and employed 1200 people. Starting in the early 70s‚ concerns have been expressed that CFCs contribute to and might cause the depletion of the ozone layer. In 1988‚ however‚ the first hard evidence was published proving that CFC causes the ozone layer to deplete. This contribution to the depletion is‚ according to the evidence‚ widespread and more severe than originally believed. In face of the new evidence‚ Joe Glas‚ CEO of Du Pont Freon Products

explanatory studies and mental model interviews that was conducted in 1994 responders regarded climate change as both bad and high likely. So far so good. But the majority of them confused stratospheric ozone depletion with the greenhouse effect which are two completely different phenomena. Explanation of ozone destruction with the two lines‚ the cloud and the human activities (a cloud that protects us from harmful sun rays. But it’s just a cloud.

Ozone is a form of oxygen that combines three oxygen atoms into each molecule. Its presence of the ozone layer in our atmosphere is crucial because it absorbs the potentially harmful ultraviolet radiation from the Sun. 1.7 3.

The destruction of stratospheric ozone by chlorofluorocarbons is sometimes mentioned in relation to global warming. Although there are a few areas of linkage‚ the relationship between the two is not strong. Reduction of stratospheric ozone has a cooling influence on the entire troposphere‚ but a warming influence on the surface. Thirdly‚ an aerosol is produced

refrigerators‚ and millions might die from food poisoning. Is that justified by saving the stratospheric ozone? It is justified because there are feasible alternative refrigeration systems that don’t emit chemical compounds that are harmful to the ozone layer. Less known refrigerants such as ammonia (NH3)‚ Carbon dioxide (CO2) and propane (C3H8) have no impact at all on global warming as well as on the ozone layer. Not only are they environment friendly‚ they are also “better than with other systems‚” said

Chemical Waste Management In the 70’s‚ there was so much neglect to the management of chemical waste. The study of chlorofluorocarbon (CFC) in the 1980’s brought more attention to chemical waste management as it was discovered that CFC depletes the ozone layer [a layer in earth’s atmosphere that protects the earth from the ultraviolet rays from the sun (UV rays)]. Dr. Rowland‚ a chemist at the University of California Irvine made up a
