What is the structural similarity between cloud and fog?
Answer and explanation
Correct answer: Tiny water droplets or ice crystals
Both clouds and fog are collections of tiny water droplets formed by condensation of water vapour; in very cold conditions, they may also contain ice crystals. Fog is essentially a cloud that forms close to the ground. Option C is a close distractor, but invisible water vapour itself is not a cloud or fog. Exam tip: distinguish cloud and fog mainly by their height or proximity to the ground, not by composition.
