Answer to Question 1

Answer: C

Answer to Question 2

Answer: Strong winds aid in the dispersal of pollutants in two ways. First, they rapidly transport emissions from their source and spread them over a wide horizontal extent. Greater wind speeds also lower the pollution concentration indirectly. Recall from Chapter 3 that air does not flow uniformly in a given direction. Instead, it contains small, swirling motions, called eddies, that mix the air vertically. This forced convection increases with wind speed and, as a result, strong winds favor greater vertical dispersion. Short-term variations in wind direction also affect dispersion. If the wind direction varies only slightly through time, pollution will be concentrated within a relatively narrow area downwind of the source. If wind directions are highly variable, the pollutants will spread out over a wider area.
