Question

A radiation fog is most likely to develop when:_________

a. the night time air is very warm.
b. the sky is full of stratus clouds.
c. the sky is clear.
d. both the night time air is very warm and the sky is full of stratus clouds
e. both the sky is full of stratus clouds and the sky is clear.

Answer 1

c. the sky is clear.

Step-by-step explanation:

• The radiation fog is formed when the land surface cools after the sunset in the conditions of the clear sky. Thus the cooling ground cools the air above it and as a result of this the conduction causes the air temperature to fall and hence it reaches the dew point and forms a fog.
