Why are dew frost fog and mist placed in the same group?

Answer and explanation

Correct answer: Because these are forms linked with condensation of atmospheric water vapour

Correct answer: B. Dew, frost, fog, and mist are different visible results of atmospheric moisture undergoing condensation. Dew is generally liquid water deposited on a cool surface, while frost is frozen deposition when the surface is sufficiently cold. Fog and mist consist of tiny droplets, or under suitable cold conditions ice particles, suspended in air near the ground. Thus their appearance and location differ, but their common basic idea is the change of water vapour into condensed water or ice. A is wrong because they are not ocean waves. C is wrong because none of them is a rock. D is wrong because earthquakes are movements of the ground and belong to a different subject. Memory cue: same process, different form or location—condensation on a surface gives dew or frost; condensation in air gives fog or mist.
