The difference between fog and smoke

The difference between fog and smog: different causes, different components, different visibility, different influence range, different formation time, etc.

1, the reason is different: fog is mainly formed by condensation of water vapor under the conditions of high humidity, stable air and low temperature, while smog is produced by atmospheric pollutants.

2. Different compositions: fog is mainly composed of water droplets formed by condensation of water vapor, while smoke is a mixture of particulate matter and toxic gases in the atmosphere.

3. Different visibility: the visibility of fog is lower than 1 km, while the visibility of fog is generally less than 5 km.

4. Different influence ranges: Fog mainly affects the visibility near the ground, and has a certain impact on traffic and daily life; The smog weather covers a wide range, which is harmful to the air quality and environment of the whole region.

5, the formation time is different: fog generally appears in the early morning or at night, and the weather is generally sunny; There is no specific time for smog to form, but it often appears during the day when pollutants are discharged more.
