Q. Which of the following statements about aerosols is not true?
Aerosols serve as condensation nuclei for clouds.
Aerosols used in cloud-seeding lead to a greater number of smaller cloud droplets.
Aerosols scatter and reflect solar radiation.
Sea salt aerosols are released into the atmosphere when the bubbles on waves burst.

Q. Governor Ron Revog wants to solve his city's smog problem (partially because he's tired of riding his bike into telephone poles). Which of the following actions would not help him meet this lofty goal?
Requiring all new construction to use low VOC paints
Covering the city with a non-porous dome
Injecting the atmosphere with hydroxide radicals.
Banning cars in the city-limits
Replacing old buses and trains with solar powered buses and trains
Q. What is one reason that soil aerosols typically do not end up in rainwater?
Soil aerosols tend to dissolve too readily in water.
Soil aerosols are too heavy to reach the layer of the atmosphere containing clouds.
Soil aerosols tend to be insoluble in water.
Soil aerosols change the size and number of cloud droplets and decrease the amount of rain.
Aerosols are never derived from soils.
