[D] Neither 1 & 2
Show Answer
Correct Answer: B [Only 2 ]
Notes:
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.
26. Which among the following is/are a characteristic feature of Air masses?
- It must be large

[C] Only 1 & 3
[D] 1, 2 & 3
Show Answer
Correct Answer: C [Only 1 & 3]
Notes:
Air masses occur over a homogeneous area, when air remains for a sufficiently long time, it acquires the characteristics of that are.
Air masses are large. A typical air mass is more than 1600 kilometres.
They have uniform properties in horizontal dimension
They must travel in a unit. It must be distinct from the surrounding area.
27. Who identified a close relationship between the distribution of vegetation and climate?
[A] Hoyle
[B] Henry Hess
[C] Laplace
[D] Koeppen
Show Answer
Correct Answer: D [Koeppen]
Notes:
Koeppen’s classification of Climatic Regions is an empirical classification based on mean annual and mean monthly temperature and precipitation data. He identified a close relationship between the distribution of vegetation and climate. He selected certain values of temperature and precipitation and related them to the distribution of vegetation and used these values for classifying the climates. He recognized five major climatic groups, four of them are based on temperature and one on precipitation.
28. Which among the following groups in Koeppen’s climate classification is used to designate Steppe’s climate?
[A] D
[B] W
[C] S
[D] E
Show Answer
Correct Answer: C [S]
Notes:
The Koeppen climate classification system recognizes five major climatic types and each type is designated by a capital letter- A, B, C, D, E, and H.
The capital letters S and W are employed to designate the two subdivisions of dry climate:
S – Semi arid or Steppe
W – arid or desert
29. Which among the following statements is/are correct about the Euphoric Zone of the ocean water?
- There is a steep fall in temperature in this zone.
- It contains about 18 percent of the total volume of water in the ocean
- It lies between 100 metres and 1000 metres.
Select the correct code from the options given below:
[A] Only 1 & 2
[B] Only 3
[C] Only 2 & 3
[D] None of the above
Show Answer
Correct Answer: D [None of the above]
Notes:
The Surface Zone is also called as the Photic zone or the Euphoric Zone. It is the upper layer of the ocean. In this layer, the temperature and salinity are relatively constant. It contains about 2 percent of the total volume of water in the ocean.
It contains about 2 percent of the total volume of water in the ocean. It is limited to a depth of about 100 meters.
