What is the primary atmospheric process responsible for the formation of frontal fog?
A. Radiation cooling of the land surface on a clear night
B. Warm, moist air moving over a cold ocean current
C. Evaporation of moisture from falling raindrops into a cold air mass below✓ Correct Answer
D. Upslope movement of air along mountain slopes
💡 Solution & Explanation
Frontal fog, also classified as precipitation fog, develops when warm rain falls through a colder layer of air near the Earth's surface, causing evaporation and subsequent air saturation. Radiation fog results from surface cooling on clear nights, while advection fog occurs when warm, moist air moves over cold surfaces.
