Which option is not a form of condensation?

Answer and explanation

Correct answer: Volcanic lava

Direct answer: D, volcanic lava. Condensation is the change of water vapour into liquid water or, in some surface conditions, directly into ice. Dew, frost, and fog are all atmospheric forms associated with this process. Dew is liquid droplets on a cool surface; frost is ice deposited on a cold surface; fog is a collection of tiny droplets suspended near the ground. A is therefore a condensation form. B is also a condensation-related form because water becomes ice crystals on a cold surface. C is a condensation form because cooled water vapour produces suspended droplets. D is wrong as a condensation form: volcanic lava is molten rock produced by geological heat, not a product of atmospheric water-vapour condensation. The wording asks for the exception, so choose the unrelated material. Memory cue: dew, frost, fog, and mist belong to atmospheric moisture; lava belongs to volcanism.
