Why can fog appear more over bridges or open fields in the morning?

Answer and explanation

Correct answer: Because open areas can cool quickly at night and saturate nearby moist air

Direct answer: A. During a clear night, an exposed bridge, road, or open field can lose heat by radiation and become cool. The moist air touching or lying close to that surface is then cooled. If its temperature reaches the dew point, the air becomes saturated and some water vapour condenses into tiny droplets. These droplets remain suspended near the ground and produce fog, especially in the early morning before sunlight warms the surface. B is wrong because a bridge does not always destroy water vapour; it may simply provide a cool exposed surface. C is wrong because open fields contain air, and gentle air movement can also occur. D is wrong because fog forms near the ground outdoors, not only underground. Memory cue: exposed surface plus moist air plus night cooling can give morning fog.
