Question

Quizplus · Accepted Answer

Radiation fog forms at night when the ground loses heat, cooling the air above it to the dew point. This typically occurs in valleys or other low-lying areas where cool, dense air settles. Advection fog forms when moist air moves over a cooler surface, such as an ocean or lake, and steam fog results from the evaporation of cold air over warm water. Precipitation fog is caused by warm rain falling into cooler air and can be found in locations such as rainforests.
