What is the term for water droplets suspended in air near the ground that reduces visibility?

• A. Mist
• B. Cloud
• C. Fog
• D. Smog

Answer: (C)

Fog forms when moist air near the ground cools to the dew point, causing tiny water droplets to condense and scatter light. That dense mist sits at ground level, so objects in the distance become hard to see, which is why visibility drops. Mist is similar but less dense, so visibility stays higher. A cloud sits high in the sky, not at ground level. Smog is polluted air that can resemble fog, but it’s related to pollution rather than just weather conditions. So, the term for water droplets suspended near the ground that reduce visibility is fog.
