Why are dew, frost, fog, and mist classified as forms of condensation?

Answer and explanation

Correct answer: Because they involve atmospheric water vapour cooling into droplets or ice

Correct answer: A. Condensation is the change in which water vapour becomes liquid water or, under sufficiently cold conditions, a solid deposit of ice. Cooling brings moist air to saturation or cools a surface enough for water to appear. Dew is made of liquid droplets on a cool surface. Frost is an icy deposit on a very cold surface. Fog and mist consist of tiny liquid droplets suspended in air near the ground. Their locations and appearances differ, but the common idea is atmospheric moisture changing from vapour into a visible liquid or solid form. B is wrong because these are not rock-forming processes. C is wrong because tides are caused by gravitational effects involving the Moon, Sun, and Earth. D is wrong because all four contain water in visible forms. Memory cue: condensation means vapour becomes visible water; the form depends mainly on temperature and location.
