Visibility is reduced in mist, yet why is it not as low as in fog?

Answer and explanation

Correct answer: Because droplet concentration is lower in mist

Correct answer: A. Mist and fog both contain tiny water droplets suspended in air, so both can scatter light and reduce visibility. The difference is mainly the amount or concentration of suspended droplets. Mist is generally less dense, so more light passes through it and distant objects remain easier to see. Fog contains a denser concentration of droplets and therefore produces a stronger reduction in visibility. B is wrong because mist does contain water droplets. C is wrong because mist is not lava and its temperature is not defined in that way. D is wrong because mist can occur during different times and is not simply invisible only at night. Thus A gives the physical reason for the difference in visibility. Memory cue: more droplets in the air means thicker obscuration and poorer visibility.
