Unlike naturally occurring sources of acid precipitation, anthropogenic sources of acid precipitation - ANSWER are more concentrated in industrial and agricultural areas. 2. Why are atmospheric carbon dioxide (CO2) levels higher in the winter than in the summer? - ANSWER Because CO2 removal decreases when trees lose their leaves in the winter 3. Many of us know of people who swear they can tell if it is going to rain by the pain in their bodies, usually their knees. It turns out that there is some truth to this. In people with joint pain, it is thought that normal atmospheric pressure helps to compress the joints (and therefore minimize the joint pain). But when atmospheric pressure (outside the body) drops, their joints swell, and it feels like there is increased pressure in their body (i.e., joint pressure, not atmospheric pressure). So, if your grandpa says he feels like his joint pressure is increasing, it is likely because atmospheric pressure is decreasing. What happens next (weather-wise)?s - ANSWER It is going to rain 4. Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death in the United States. This disease primarily affects - ANSWER the respiratory passageways and alveoli of the lungs. 5.

Then it occurs to you that this is probably because of the impact of - ANSWER the jet stream. 7.

Fewer fish in reefs that form on oil rigs in the Gulf of Mexico d. Fewer dolphins contributing to a decline in biodiversity - ANSWER Less fossil fuel use resulting from less drag and more efficient transit of ships through water 14. With respect to the Kannan paper, what was the difference between biomagnification and bioaccumulation? Select one: a. Biomagnification would be the result of the dolphins eating oysters that had eatent TBT-contaminated plankton, and bioaccumulation would be the result of a build-up of TBT in the tails of the dolphins. b. Biomagnification would be the result of the dolphins eating TBT contaminated plankton, and bioaccumulation would be the result of a build-up of TBT in the lungs of the dolphins. c. Biomagnification would be the result of the dolphins eating shrimp that had eaten TBT-contaminated plankton, and bioaccumulation would be the result of a build-up of TBT in the fatty tissues of the dolphins. d. Biomagnification would be the result of the dolphins eating crabs that had eatent TBT-contaminated plankton, and bioaccumulation would be the result of a build-up of TBT in the blowholes of the dolphins. - ANSWER Biomagnification would be the result of the dolphins eating shrimp that had eaten TBT-contaminated plankton, and bioaccumulation would be the result of a build-up of TBT in the fatty tissues of the dolphins. 15.
