Question

Natural phenomenon like fog, mist or frost are caused due to __________

• A. Evaporation
• B. Transpiration
• C. Condensation
• D. Freezing

Answer 1

The correct option is C

Condensation

The correct option is (C):-

Explanation for the correct option is:

Condensation:-

1. It is actually a chemical process in which the water is condensed back from the form of vapor or gaseous.
2. This process is actually the reverse of the vaporization one.
3. This condensation process can be done in one or two ways.
4. Either the air is cooled to the dew point or it will become saturated with the water vapor such that it can not hold any other water.
5. So, the Fog, mist or frost present in the atmosphere are caused because of the natural phenomenon Condensation.

Therefore, the correct answer is (C):- Condensation

Explanation for the incorrect options:

Option (A):- Evaporation

1. It is actually a form of vaporization and this usually happens on the surface of the liquids.
2. In it there is the change from the liquid phase to the gaseous phase.

Option (B):- Transpiration

1. It is the evaporation process of water from the plants.
2. This process occurs at the surface of the leaves through the stomata which are the tiny pores and helps in the transfer of some gases and these water vapors.

Option (D):- Freezing

1. This process is also known as solidification which will only happen when the temperature will get lowered below the particular freezing point.
2. It is basically a phase transition where the liquid form will change into the solid .
