31. Consider the following:
- Geological time period
- Nature and structure of rocks
- Topography
- Slope
- Periodicity of the flow
Which of the above is/are responsible factors for drainage pattern of an area?
[A] Only 1, 3, and 5
[B] Only 1, 2, and 3
[C] Only 2, 4, and 5
[D] All of the above
Show Answer
Correct Answer: D [All of the above ]
Notes:
The flow of water through well-defined channels is known as ‘drainage’ and the network of such channels is called a ‘drainage system’. The drainage pattern of an area is the outcome of the geological time period, nature and structure of rocks, topography, slope, amount of water flowing and the periodicity of the flow.
32. Which of the following are Special Administrative Regions (SARs) of China?
- Hong Kong
- Taiwan
- Macau
- Tibet
Select the correct answer using the codes given below:
[A] Only 2
[B] Only 2 & 4
[C] Only 1 & 3
[D] 1, 2, 3 & 4
Show Answer
Correct Answer: C [Only 1 & 3]
Notes:
Hong Kong and Macau are the only Special Administrative Regions (SARs) of China, established under the “one country, two systems” principle after their handover from Britain and Portugal, respectively. Taiwan is claimed by China but is not an SAR, while Tibet is an autonomous region, not an SAR.
33. Consider the following statements:
- A ship at sea is not much affected by tsunami.
- It is difficult to detect a tsunami in the deeper parts of sea.
- When a tsunami enters shallow water, its wavelength gets reduced and the period remains unchanged.
Which of the above statements is / are correct?
[A] Only 1 and 2
[B] Only 1 and 3
[C] Only 2 and 3
[D] All of the above
Show Answer
Correct Answer: B [Only 1 and 3]
Notes:
A ship at sea is not much affected by a tsunami as the wave height in deep water is small and the wavelength is long, making it hard to detect. When a tsunami enters shallow water, its wavelength decreases while the wave period remains largely unchanged, resulting in an increase in wave height. Thus, statements 1 and 3 are correct.
34. Consider the following:
(Cultivation regions: Country)
- Steppes: Eurasia
- Downs: New Zealand
- Canterbury Plains: Australia
- Pampas: South Africa

Which of the above is/are incorrectly matched?
[A] Only 1 and 2
[B] Only 3, 4, and 5
[C] Only 2, 3, 4, and 5
[D] All of the above
Show Answer
Correct Answer: C [Only 2, 3, 4, and 5]
Notes:
Commercial Grain Cultivation is best developed in Eurasian steppes, the Canadian and American Prairies, the Pampas of Argentina, the Velds of South Africa, the Australian Downs and the Canterbury Plains of New Zealand.
35. Consider the following:
(Large integrated steel industry centres : Country)

- Dusseldorf: France
- St. Etienne: Germany
- Lipetsk: Russia
Which of the above are correctly matched?
[A] Only 2 and 3
[B] Only 1 and 4
[C] Only 1, 2, and 3
[D] All of the above
Show Answer
Correct Answer: B [Only 1 and 4]
Notes:
The important steel centres are Scun Thorpe, Port Talbot, Birmingham and Sheffield in the U.K.; Duisburg, Dortmund, Dusseldorf and Essen in Germany; Le Creusot and St. Etienne in France; Moscow, St. Petersburgh, Lipetsk, Tula, in Russia and Krivoi Rog, and Donetsk in Ukraine.
36. Consider the following:
(Ports : Country)
- Maracaibo: Venezuela
- Esskhira: Lebanon
- Tripoli : Tunisia
Which of the above are matched correctly?
[A] Only 2 and 3
[B] Only 2
[C] Only 1
[D] All of the above
Show Answer
Correct Answer: C [Only 1]
Notes:
Oil Ports deal in the processing and shipping of oil. Some of these are tanker ports and some are refinery ports. Maracaibo in Venezuela, Esskhira in Tunisia, Tripoli in Lebanon are tanker ports. Abadan on the Gulf of Persia is a refinery port.
37. Which of the following is/are correct for climate?
- Variations that occur on day-to-day basis.
- It is the average weather condition.
- Climate chart is annual record of average temperature and rainfall.
Select the correct answer from the codes given below:
[A] Only 1 and 2
[B] Only 2 and 3
[C] Only 1 and 3
[D] All of the above
Show Answer
Correct Answer: B [Only 2 and 3]
Notes:
The records of the weather have been preserved for the past several decades. These help us to determine the weather pattern at a place. The average weather pattern taken over a long time, say 25 years, is called the climate of the place. The annual record of long term average temperature and rainfall at a particular place is called climate chart.
38. Which of the following phenomena occur in Arctic Ocean?
- West Wind Drift
- Transpolar Drift Stream
- Beaufort Gyre
Select the correct option from the codes given below:
[A] Only 1 & 2
[B] Only 2 & 3
[C] Only 1 & 3
[D] 1, 2 & 3
Show Answer
Correct Answer: B [Only 2 & 3 ]
Notes:
The Antarctic Circumpolar Current, or West Wind Drift, is the world’s strongest ocean current, flowing unimpeded around Antarctica in the Southern Ocean. The Transpolar Drift Stream is a significant Arctic Ocean current that moves sea ice from the East Siberian and Laptev Seas to the Fram Strait. The Beaufort Gyre, also in the Arctic Ocean, has become a repository for older ice.
39. Which of the following countries have their coast along with the Mediterranean sea?

[C] Only 2 & 3
[D] Only 2, 3 & 4
Show Answer
Correct Answer: A [Only 1 & 2 ]

Libya, a North African country in the Maghreb region, is bordered by the Mediterranean Sea to the north. Tunisia, the northernmost African country, is also in the Maghreb and has the Mediterranean Sea to its north and east. Serbia is a landlocked country in the Balkan Peninsula, while Romania, located in Europe, is bordered by the Black Sea to the southeast and does not have a Mediterranean coastline.
40. Consider the following statements:
- Zero Shadow Day is observed in places that lie above the Tropic of Cancer and below the Tropic of Capricorn.
- Day Zero is the day when the taps in an area will run dry.
Which of the statements given above is/are correct?
[A] Only 1
[B] Both 1 and 2
[C] Only 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: C [Only 2]
Notes:
Zero Shadow Day occurs in locations between the Tropic of Cancer and the Tropic of Capricorn, not above or below them. Day Zero refers to the day taps run dry due to extreme water shortage, as first discussed in South Africa. Thus, only statement 2 is correct.
