B)Upslope fog.
C)Evaporation fog.
D)Radiation fog.

Question

Quizplus · Accepted Answer

Cooling of the surface at night causes the air layer near the surface to cool, which may lead to the formation of radiation fog. Advection fog is formed when warm, moist air moves over a cooler surface. Upslope fog is formed when warm, moist air rises along a slope and cools. Evaporation fog occurs when cold air moves over a water surface, causing the water to evaporate and condense into fog. None of these processes are associated with cooling of a surface overnight that chills the air layer directly above that surface.
