Question

Quizplus · Accepted Answer

Radiation fog forms at night when the ground cools rapidly due to clear skies, calm winds, and high humidity. This causes the air near the ground to cool and become saturated which leads to the formation of fog. Warm air is less likely to produce this type of fog, and the presence of clouds or precipitation prevent or reduce the cooling of the ground necessary to form radiation fog.
