Fog vs Mist
• When conditions are such that temperatures are low and light wind is blowing, moisture in the air starts to condense into tiny water droplets. These droplets look like a cloud and reduce visibility to a great extent. This natural weather phenomenon is referred to as fog.
• Mist is similar to fog and the only difference lies in their densities. A mist is much less dense than fog and it is said to be a mist if visibility is greater than 1km. It becomes a fog if one can see less than 1 km.
