3. What is fog ?
• Fog is a complex atmospheric phenomenon. It is a visible
mass consisting of cloud water droplets or ice crystals
suspended in the air at or near the Earth's surface.

4. As there is fog?
• Fog can be considered a type of low-lying cloud, and is
heavily influenced by nearby bodies of water, topography,
and wind conditions. In turn, fog has affected many
human activities, such as shipping, travel.

5. Types
• Fog forms when the difference between air temperature
and dew point is generally less than 2.5 °C or 4 °.
• Fog begins to form when water vapor condenses into tiny
liquid water droplets suspended in the air.

6. • Fog can form in a number of ways, depending on how the
cooling that caused the condensation occurred.
