Page 408 Box 15.1 (Altering the Atmosphere’s Composition- Sources and Types of Air Pollution) 1.) New Information Learned: A.) Air pollutants are airborne particles and gases. B.) Primary pollutants pollute the air immediately upon being emitted. C.) 49.1% of primary pollutants are Carbon Monoxide. D.) Secondary pollutants are not emitted directly into the air. E.) Many reactions that produce secondary pollutants are triggered by sunlight.

2.) This article to me was very interesting. It had a lot of informative facts that really helped me understand the article a lot more. The graphs also helped me a lot with understanding what kinds of Primary Pollutants are and how much there is. All in all this was a great article to read. 3.) I didn’t find much in this article that I didn’t like. However, I do wish there was more pictures in it. The graphs were great, just a little more information would have been nice to see along with the pictures. Also, I wish there was more information on how these pollutants work. 4.) Air pollutants can be very dangerous to us. If we breath in the wrong kind, it could kill us. Many people don’t realize, but our cars and trucks are a major contributer to air pollutants. For example, nitrogen oxides can absorb solar radiation which can cause us to have cold climates.

Page 410 Box 15.2 (Ozone Depletion-A Global Issue) 1.) New Information Learned: A.) Nearly a billion years Earth’s ozone layer has protected life on the planet. B.) Chlorofluorocarbons are nontoxic, noncorrosive and you can use it for a lot. C.) Paul Crutzen, F. Sherwood Rowland and Mario Molina won a Nobel Proze in 1995 for Chemistry. D.) The most serious threat to human health is an increased risk of skin cancer. E.) CFC levels in the atmosphere will not drop rapidly.

2.) Something that really spoke to me in this article was how they clearly explained a lot about CFC’s. I didn’t really have a good understanding about this topic but once I read this article, I had a clear understanding of it. It also had a lot of facts that really helped me while reading this. 3.) While reading this article, I noticed a couple of things I didn’t like. Looking at Figure 15.C, I didnt really understand why the globe was there. I would have liked to see pictures that showed CFC’s and what kind of things it was in. I also think it wasted a little room telling what CFC was in.

4.) A lot of people don’t know what CFC’s but if they read this article, they will. CFC’s are versatile compounds that are chemically stable, odorless, nontoxic, noncorrosive, and inexpensive to produce. So yes they can be very useful to us in the world. We use CFC’s in a lot of places to help us live, not saying we cant live without it.

Page 424 Box 15.3 (Showing Temperature Distribution Using Isotherms)

New Information Learned A.) An isotherm is a line that connects points on a map that have the same temperature. B.) Iso = equal, therm =temperature C.) Isotherms can be drawn on maps. D.) Areas of low and high temperatures are easy to pick out. E.) Without isotherms, maps would be covered in numbers showing the temperature.

2.) When I first started reading this article, I didn’t really like it. But once I kept reading it kept getting very interesting. I really liked how they used a map to show a visual of what Isotherms look like. Also, I liked how they broke down the word Isotherm to kind of give us a better understanding of what it really is.

3.) I really didn’t find anything I didn’t like about this article. However, I wish it was a little bit longer to give us a better understanding of what it is. Also, I wish it broke down on how a isotherm is organized and what different temperatures are together in a section.

4.) Isotherms help us understand what temperature looks like on a map and how its organized. This helps us have a better understanding on how temperatures
