Four quick points before solutions and analysis

1. This is the solution and analysis of geography questions from CAPF 2016 conducted by UPSC couple of weeks back.
2. Focus on doable questions <and most of the questions are doable without too much mugga>
3. Almost all the questions can be solved after reading NCERT physical geography and geography of INDIA so focus on that
4. Analysis of CSE prelims geography would be done in days to come

1. Which one of the following layers of atmosphere has high concentration of ions?

a)Stratosphere (b) Exosphere
(c) Thermosphere
(d) Troposphere

• Can’t get this wrong
• Every one would have answered if they had said ionosphere. 
• Ions would be formed if there is high temperature so thermosphere

2) Which one of the following cities has greater annual range of temperature?
(a) Kuala Lumpur
(b) New Delhi
(c) Shanghai
(d) Ulaanbaatar

• Shanghai and Kualalampur are port cities. Marine environment. Sea moderates the climate easily excluded
• B/w Delhi and Ulaanbataar  (capital of mongolia) remember pm modi visited mongolia
• Now you read in geography – Himalayas blocking chilly cold winds from the north. So Delhi and Northern India does not freeze but ulanbator does. Would have greater range of temperature
• Also if you had solved previous years question papers or read climatoligy, you would know steppes have extreme climate. Mongolia – steppes

3) Match List I with List II and select the correct answer using the code given below the Lists :

List I List II
(Climate type in letter code) (Major area)
A. Aw 1. Central California
B. Af 2. Indian Sub-Continent
C. Cs 3. North and South of Amazon Forests
D. Am 4. Western Equatorial Africa
Codes
A B C D
(a) 3 1 4 2
(b) 2 4 1 3
(c) 3 4 1 2
(d) 2 1 4 3

• From ncert koppen system of classification
• m is for monsoon so d would be matched with 2, exclude b and d
• A is for tropical, Af is tropical evergreen i.e equatorial i.e 4
• Answer is clear now
• Aw is tropical Savannah
• Learn this system from NCERT

4. Which one of the following rivers flows between Satpura and Vindhya ranges?(a) Tapi
(b) Sabarmati
(c) Narmada
(d) Mahi

• Very easy
• Narmada river flows through a rift valley b/w Satpuras and Vindhya

5. How is the rate of transpiration affected by decreasing humidity and by decreasing light intensity?
Decreasing humidity Decreasing light intensity
(a) Decreases Decreases
(b) Increases Decreases
(c) Increases Increases
(d) Decreases Increases

• Simple
• If humidity increases, already mote water in the atmosphere so obviously rate of transpiration would slow down
• Similarly if light intensity is more there would naturally be more evaporation more transpiration

6. Consider the following statements relating to Sea Salinity:
1. The ocean salinity depends on evaporation and precipitation
2. Any change in the temperature or density influences the salinity
3. Major source of sea salinity is terrestrial discharge by rivers
Which of the statements given above are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

• I is easily true. More evaporation means more salt left behind, more precipitation means more fresh water
• If temperature is more, there would be more evaporation
• 3rd is a fact <do check it again, i am not very sure about 3rd but I think it’s correct
• http://oceanservice.noaa.gov/facts/whysalty.html

7. Consider the following statements relating to salt production in India:
1. India is the second largest producer of iodised salt in the world next only to China
2. Salt mining is carried out in Himachal Pradesh
3. Gujarat is the leading producer of salt in India
4. Ground water is the important source of salt in Rajasthan
Which of the statements given above are correct?
(a) 1 and 2 only
(b) 3 and 4 only
(c) 1, 2 and 3
(d) 2, 3 and 4

• 3rd is easily true – Salt by evaporation in tropical seas, wind conditions, question has been asked in mains for salt indutsries in Gujrat, dandi March in Gujarat, >75% of total salt in India in Gujrat
• 4th is also true – sambhar lake
• Salt mining was carried out in Himachal Pradesh but stopped in 2011. There’s again propsal to start salt mining in Himachal

8. Which of the following statements relating to Dharwar geological system are correct?

1. They belong to Archaean geological period
2. They are metamorphosed sedimentary rocks
3. They are of great economic importance for its mineral resources
4. They are found predominantly in Karnataka, Tamilnadu, Odisha and Jharkhand
Select the correct answer using the code given below :
(a) 1, 2, 3 and 4
(b) 2, 3 and 4 only
(c) 3 and 4 only
(d) 1 and 2 only

• Geology of India is very imp. Learn it in detail. It would help you solve many questions related to chronology and minerals, hydrocarbons etc.
• Archean is the oldest rock system found in aravalis not in dharwar and part of Deccan peninsula
• Dharwar is 2nd oldest
• name Dharwar itself suggest karnataka

9. Which one of the following is the correct order of formation of geological systems in India in terms of their age? [Starting with the oldest]
(a) Dharwars – Aravallis – Vindhyans – Cuddapahs
(b) Aravalis – Dharwars – Cuddapahs – Vindhyans
(c) Vindhyans – Dharwars – Aravallis – Cuddapahs
(d) Cuddapahs – Vindhyans – Dharwars – Aravallis

• Arawali everyone knows is the oldest. Only option is b
• Dharwar 2nd oldest as we saw in previous question

10. Which one of the following statements is not correct?
(a) The rate of evaporation depends on temperature
(b) The rate of evaporation does not depend on surface area exposed to the atmosphere but on volume of the liquid
(c) The rate of evaporation depends on humidity of the surroundings
(d) The rate of evaporation depends on the wind speed

• Sort of internal repeat
• A and c we have seen in the question on transpiration
• High wind speed means wind will take away the atmospheric moisture so more evaporation
• B is anyway a negative statement # red flag # pause and think # high surface area means more area from which evaporation can take place

11. Which of the following statements are correct?
1. Kolkata port is the only riverine major port of India
2. The port of Cochin is located on the Willington Island
3. Maharashtra has three major ports
4. Mundra port is India’s major port in private sector
Select the correct answer using the code given below:
(a) 1and 2 only
(b) 3 and 4 only
(c) 2, 3 and 4 only
(d) 1, 2 and 4

• 4th is wrong. We had done this in titbit
• Learn about ports from titbit
• Ennore port is the only major port in private sector

12. Perth located on 118th East Longitude will be celebrating New Year event on 1st of January 2017 at 6:00 AM . At that time, what would be time at Los Angeles located on 1100 West Longitude?
(a) 9 : 12 PM of 1st January 2017
(b) 2:48 PM of 31st December 2016
(c) 11: 40 PM of 31st December 2016
(d) 5 : 28 AM of 1st January 2017

• Difference is of 228 degree
• 360 degree equivalent to 24 hrs
• 228 (240) would be equivalent to around 16 hrs
• West hence behind, so obviously 31st dec, 16 hrs behind

13. Arrange the following varieties of silk in India in their order of decreasing production:

(b) 3- 4 – 2- 1
(c) 2 – 4 – 1 – 3
(d) 2- 1 – 4 – 3

• No option but to mug up
