Fog, mist or frost are due to condensation, depending upon the physical conditions of atmosphere.

Becoz condensation is a process in which liquid change in gas contain natural the phenomenal form ....eX:- fog, mist ...etc etc etc

Natural phenomenon like fog, mist or frost are caused due to a process called condensation.

Condensation:

Condensation is the process by which a gaseous substance is converted into a liquid state. Condensation takes place when the temperature of the air is lowered to its dew point, which is the temperature at which the air becomes saturated with water vapor.

Causes of Fog, Mist or Frost:

1. Fog:

Fog is a type of cloud that forms close to the ground. It is caused by the condensation of water vapor in the air. Fog occurs when the air is cooled to its dew point and the water vapor in the air condenses into tiny water droplets.

There are different types of fog:

- Radiation fog: It forms during clear nights when the ground cools the air above it.

- Advection fog: It forms when warm, moist air moves over a colder surface.

- Upslope fog: It forms when moist air moves up a slope and cools.

2. Mist:

Mist is similar to fog but it is not as dense. It is created when the water droplets in the air are larger than in fog. Mist is usually found in areas with high humidity, such as near lakes or rivers.

3. Frost:

Frost is formed by the deposition of water vapor onto a surface that is at a temperature below freezing. Frost forms when the temperature of the air is below freezing and the moisture in the air condenses directly onto a surface in the form of ice crystals.

Conclusion:

In summary, natural phenomena like fog, mist, or frost are caused by the process of condensation. When the temperature of the air is lowered to its dew point, the water vapor in the air condenses into tiny droplets or ice crystals, leading to the formation of fog, mist, or frost.
