Textbook Question
Chapter 56, Problem 13TYK
Thinning of the ozone layer is a result of CFCs introduced into the environment. Although global release of CFCs has been dramatically reduced, the ozone layer is recovering very slowly because
- a. chlorine from CFCs persists in the atmosphere, continuing to break down ozone.
- b. CFCs don’t break down in the atmosphere.
- c. other compounds with the same effects as CFCs are being released.
- d. greenhouse gas emissions also damage the ozone layer.

a. true
b. false
We learned an ironic twist in the film called "The Other Inconvenient Truth." It was that
a. agriculture creates more pollution than other sources, but we have to increase farming for the growing population
b. that nitrogen in the soil is significant pollution, but if we don't use these fertilizers we will not have enough food
c. That methane is produced by animals and by growing rice. So becoming vegetarian won't clear methane from the atmosphere.
d. agriculture uses 70% of fresh water mined , causing a salt water pollution too

In this week's lab exercise you will examine levels of air pollution in the Phoenix Metropolitan area. The measurable levels of different pollutants indicate an overall air quality index (AQI). Anthropogenic sources of pollution (Carbon monoxide, Ozone) are a major contributor to higher AQI values but particulate matter (PM-10) is also important in determining an AQI score. Choose all listed sources that would contribute to increased particulate matter (PM-10) levels. and EXPLAIN WHY YOU CHOOSE IT. DEFEND YOUR ANSWER choices: a. Water vapor from Tempe town Lake and local water parks b.Bovine flatulence from Shamrock Farms c.Dust from empty construction lots or a recent HABOOB! d.
