B)Clear skies,windy,humid air at the surface
C)Clear skies,light winds,humid air at the surface
D)Cloudy skies,light winds,humid air at the surface

Question

Quizplus · Accepted Answer

in order to create radiation fog, the ground must cool rapidly at night, causing the moisture in the air to condense and form fog. Clear skies allow for more radiation to escape into the atmosphere and cool the surface, which is why A and B are incorrect. Light winds are necessary to keep the moist air near the surface and prevent it from mixing with drier air aloft, which would prevent the fog from forming. Additionally, humid air at the surface provides the moisture necessary for fog formation. Therefore, the correct answer is C. Option D is incorrect because cloudy skies would prevent the ground from cooling as rapidly and therefore hinder the formation of radiation fog.
