Air mass is a large body of air whose physical properties especially temperature and moisture content are relatively uniform horizontally. The temperature, pressure and humidity are uniform and the whole area of air or the mass of air behaves like a single unit.
28. Which among the following statements is/are correct about cold and warm air masses?
- A cold air mass is one which is colder than the underlying surface and is associated with stable weather conditions.
- A warm air mass is one which is warmer than the underlying surface and is associated with instability and atmospheric turbulence.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: D [Neither 1 & 2]

Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: B [Only 2]
Notes:
Cyclone is any low-pressure area with winds spiralling inwards. Cyclones rotate anti-clockwise in Northern Hemisphere and clockwise in Southern Hemisphere. The process of Cyclone formation and intensification is called Cyclogenesis.
30. Which among the following statements is/are correct about Atolls?
- An atoll is a roughly circular oceanic reef system surrounding a large central lagoon.
- Atolls are far more common in the Atlantic than any other ocean.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: A [Only 1]
Notes:
An atoll is a roughly circular (annular) oceanic reef system surrounding a large (and often deep) central lagoon.
The lagoon has a depth 80-150 metres and may be joined with sea water through a number of channels cutting across the reef. Atolls are far more common in the Pacific than any other ocean.
