4) Section 8.3 Question #1: Water molecules absorb infrared light, but water vapor is not believed to contribute to global warming. Why not? Seeing as it is greenhouse gases the affect global warming on our planet, it would be assumed that the most abundant natural greenhouse gas would contribute to global warming; however, water vapors do not contribute to global warming at all. The reason water vapors do not contribute to global warming is because the concentration of water vapor in the atmosphere fluctuates depending on different seasons and locations. It is also hard to tell the effect that water vapors have on the atmosphere because of water’s transitions between its different states of liquid, solid, and gas. 5) Section 8.3 Question #2: In what ways does deforestation contribute to the increase in greenhouse gases in the atmosphere? Greenhouse gases that are emitted into the atmosphere that efficiently capture heat cause what is known as the greenhouse effect. As inhabitants of this earth, humans have greatly contributed to the impact of greenhouse gases being released into the atmosphere. The most notable way in which humans have contributed to the greenhouse effect is by increasing the amount of carbon dioxide in the atmosphere. Since trees are the holders of carbon dioxide, and without them, there is more carbon dioxide in the atmosphere. This

means that when humans cut down trees and go through deforestation, the amount of carbon dioxide in trees is reduced while the amount in the atmosphere increases and adds to the emission of greenhouse gases. Chapter 9 1) Section 9.1 Question #2: What is the difference between point and non-point-source pollutants? How might this difference influence their dispersion in the environment? There are many pollutants that are released into the atmosphere, but there are also many other gases that are generated in the atmosphere by reactions stemming from gases and aerosols. The gases that are released directly into the atmosphere are known as primary air pollutants or point-source pollutants. These primary air pollutants come from identifiable sources that are known; for instance, volcanic explosions release elemental mercury into the atmosphere. While these pollutants have an identifiable source, secondary air pollutants, or non-point-source pollutants, do not. Instead, these “secondary air pollutants are chemicals or particles that are produced in the atmosphere as a result of reactions among chemicals and aerosols” (239). An example of a secondary air pollutant would be the ozone that builds in the city air during the daytime; a secondary air pollutant that is facilitated by sunlight is also known as a photochemical. The difference between these two types of air pollutants and their influence on dispersion in the environment is that it is unknown when and where non-point-source pollutants come from while point- source pollutants are known.
