    a) Rayleigh
    b) Mie

  2. Haze droplets form over New York City. At this stage of growth, what process will more than likely determine whether an individual droplet grows beyond its present size, evaporates, or remains as it is.
    a) curvature effect
    b) solution effect
    c) diffusion
    d) collision - coalescence

  3. How is it possible for air to have a relative humidity greater than 100%?
    a) The presence of aerosols provide a surface for the water vapor to condense onto. As a cloud grows the water content increases, and the level of supersaturation increases.
    b) When air is said to be supersaturated, it is only with respect to a plane surface of water or a plane surface of ice. Condensation begins when air above a flat surface of water has a relative humidity of 100%.
    c) It is not possible. The presence of aerosols prevent atmospheric air from getting supersaturated. With the presence of aerosols, condensation begins when the relative humidity is 100%.

  4. Which of the following compounds is not involved in the formation of photochemical smog?
    a) NO2
    b) O3
    c) VOC's
    d) CO2

  5. What atmospheric phenomenon occurring in our national parks serves as a monitoring mechanism for air quality throughout the US?
    a) haze
    b) fog
    c) smog
    d) smoke
