What is the main difference between cloud and fog?
Answer and explanation
Correct answer: Clouds form at a height in the atmosphere, whereas fog forms near the ground
Clouds and fog are both collections of tiny condensed water droplets or ice crystals in the air. The main difference is their height: clouds usually form above the Earth's surface, while a cloud forming close to the ground is called fog. Option B is incorrect because both may contain water droplets and/or ice crystals; fog is not water vapour but condensed droplets. Exam tip: remember, ‘a cloud near the ground is fog.’
