Question

In the winter season, dense fog and frost arise over ____.
A) North India simple
B) Coastal plains
C) Island
D) Tamil Nadu Plains

Answer 1

Hint: The main distinction between Fog and Frost is that the Fog is an atmospheric phenomenon and Frost is a coating or deposit of ice that may shape in humid air in cold conditions, normally in a single day Fog is water vapour condensing to visible ranges near the floor.

Complete Answer:
- Dense fog is seen during winter within northern India. The motive for fog in North India is entirely due to a weather system known as Western Disturbance.
- This is the surprising reversal of dry and funky northwesterly to humid easterlies or south easterlies that may motivate full-size fog within the plains of North India.
- As the winds are calm and slow with the velocity below 5 km ph within northern India at some stage in this season, the fog settles and keeps to stay at some stage in.
- A temperature at or beneath freezing is not important to get floor frost or hoar frost; they can form even though the air temperature is above freezing point if the sky is apparent. That is because the ground loses warmth because of radiation. It radiates its warmness to the sky/space.
- When you "experience" a completely bloodless surface, it's miles because you're radiating your warmth to that bloodless surface, the bloodless surface turns hotter, and also you come to be colder. The quantity of warmth that radiates is proportional to the distinction in temperature among the 2 objects.

Hence option A is the right answer.

Note: Fog or smoke are taken into consideration when the visibility is diminished to $\dfrac{1}{4}$ of a mile or much less. The aggregate of smoke and fog is a very dangerous scenario that may lower visibility to 0. If dense fog is predicted or located over a massive sufficient vicinity.
