Why can fog cause delays in air and road transport?

Answer and explanation

Correct answer: Because visibility decreases

Correct answer: A, because visibility decreases. Fog consists of many tiny water droplets suspended near the ground. These droplets scatter light and make distant objects, road markings, signals, runways, and other vehicles harder to see. Drivers may need to reduce speed and maintain greater caution. Aircraft operations can also be delayed because pilots and airport systems require adequate visibility for safe take-off, landing, and movement. A is correct because reduced visibility creates a safety problem; it does not mean that all transport must always stop. B is wrong because air does not disappear when fog forms. C is wrong because fog does not melt roads. D is wrong because fog does not change the mass or weight of vehicles. Fog can sometimes be accompanied by other weather conditions, but the direct reason asked here is reduced visibility. Memory cue: fog blocks the view, so transport must slow down or wait.
