Mist and fog are both linked with which water cycle process?

Correct answer: Condensation

Correct answer: C. Condensation is the process in which water vapour changes into liquid water droplets, usually when moist air cools to saturation. Mist and fog are both collections of tiny suspended water droplets near the ground, so they are atmospheric forms of condensation. The difference between them is mainly related to the degree of visibility reduction, not to a different water-cycle process. Option A, weathering, is the breakdown of rocks at or near Earth’s surface and does not describe droplet formation. Option B, meandering, describes the curving course of a river and is unrelated to atmospheric moisture. Option C is correct because cooling and condensation create the droplets of mist and fog. Option D, tide, is the periodic rise and fall of sea level, mainly associated with gravitational effects, not the formation of these droplets. Memory cue: vapour plus cooling gives condensation; suspended droplets near the ground give mist or fog.
