Q. Which of the following statements regarding Fog and Mist are correct?

1. Fog contains more moisture than mist
2. Fog is formed generally when warm and cold currents meet
3. Fog is a cloud with its base at or very near to ground
4. Mist is formed frequently over the mountains when rising warm air up the slopes meets cold surfaces

Select the correct option from the codes given below:
Answer: Only 2, 3 & 4
Notes: Fog is formed when warm and cold air currents meet and is described as a cloud near the ground. Mist often forms over mountains when warm, rising air meets cold surfaces. Mist contains more moisture than fog, not vice versa, so statement 1 is incorrect. Statements 2, 3, and 4 are correct based on meteorological definitions.
