Except the Volga river and jet streams, others MCQs are asking such details, which are not directly solvable from the routine books.
Therefore, majority of the questions are medium to tough categories.
|Geography in 2015 to 2019 Prelim Papers||2020 Prelims: Continuity and change in the Geography questions|
|The number of MCQs from Geography reduced from two-digit to single digit to make space for Environment and Agriculture.
Since Prelims-2016, Geography has been receiving alternate weightage of 4MCQ-7MCQ-4MCQ-7MCQs.
|Pattern continued, this year 5 MCQ. Although in Mains GS Paper-1, 100+ marks worth Geography is asked so it’s not like UPSC is showing ‘disrespect’ to the subject.|
|-Low profile tributaries of famous rivers asked e.g. Godavari, Bramhaputra, Teesta in 2015, 2016 and 2017 respectively.
-In 2019 UPSC examination gone crazier than usual: 2 MCQs on Indian rivers.
|Nothing from Indian rivers but asked from world rivers|
|– 2019: Glacier vs river pair question asked.||One question about Glacier map location|
|There had been a trend of asking about particularly Vulnerable Tribal Groups (PVTGs) every few years.||Not seen in this time|
|– 2019: 5 out of 7 Geography MCQs are based on maps.||– 2 out of 5 Geography MCQs Based on maps|
|– 2019: An MCQ on Minor and major minerals with regards to regulatory powers of the Union and State Government||– Asked about the classification of the minor and major minerals.|
|Physical geography questions in 2019 paper were relatively easier.||asked technical things about Ocean Mean Temperature (OMT) lifted from the Hindu Article 2 years ago. So physical geography relatively difficult than last year|
Anyways, when barely 5 questions are asked, there is not much left to compare and contrast and analyse and strategize in comparison with past year.
Covered in a separate article Mains GS Paper-1- including topicwise previous papers!
(Pre’20-SetB) Q.53. With reference to Ocean Mean Temperature (OMT), which of the following statements is/are correct?
- OMT is measured up to a depth of 26°C isotherm which is 129 meters in the south-western Indian Ocean during January – March.
- OMT collected during January March can be used in assessing whether the amount of rainfall in monsoon will be less or more than a certain long-term mean.
Select the correct answer using the code given below[a) 1 only
[b) 2 only[c) Both 1 and 2 [d) Neither 1 nor 2
Difficulty : Tough 🥵 this much information is not available in routine books. It seems to be lifted from of random The Hindu article published 2 years ago
Type: Theory 📚
- In contrast, OMT, which is measured up to a depth of 26 degree C isotherm. During January–March, the mean 26 degree C isotherm depth in the Southwestern Indian Ocean is 59 metres. So, #1 is wrong.
- Sea surface temperature (SST) is routinely used for predicting whether the total amount of rainfall that India receives during the monsoon season will be less or more than the long-term mean. However, ocean mean temperature (OMT) has better ability to predict this, than SST. So, #2 is correct.
- 2018-September’s Thehindu Article. But it is unlikely that a candidate may have read and remembered such an old information therefore I have classified it under “random source”.
🎲 GuessMaster-GiriTM: 🤙Partially Possible If you believe in the rule#2 that GM-Rule#2: Dates, Years & figures are always wrong in statement → Then first statement should be wrong because they contains data related to temperature and depth, so, we are We are 50:50 between B or D.
(Pre’20-SetB) Q.59. Consider the following statements:
- Jet streams occur in the Northern Hemisphere only.
- Only some cyclones develop an eye.
- The temperature inside the eye of a cyclone is nearly 10 C lesser than that of the surroundings.
Which of the statements given above is/are correct:[a) 1 only [b) 2 and 3 only
[c) 2 only[d) 1 and 3 only
Difficulty : Medium 🧐 Requires knowledge over multiple statements.
Type: Theory 📚
- As per Tamil Nadu Class11 Geography Book:
- Jet streams are high altitude westerly wind system blows at a height of 6 to 14 km, with very high speed up to 450 km/hr in wavy form at both hemispheres. → #1 is wrong.
- Centre of the cyclone is called the Eye. The eye is a Calm region with no rainfall and experiences highest temperature and lowest pressure within the cyclonic system. → #3 is wrong. So, by elimination, Answer is C.

- Explained – Cyclone – https://www.youtube.com/watch?v=p3Dseym4Le8
🎲 GuessMaster-GiriTM: 👍Fully Possible.
- If you believe in the rule#1 that extreme worded statements are always wrong → Then first statement#1 should be wrong because contains extreme words “only”
- If you believe in the rule#2 that GM-Rule#2: Dates, Years & figures are always wrong in statement → Then statement#3 should be wrong because contains a figure “10C”.
- Thus by elimination, we get answer C, #without-studying-anything.
(Pre’20-SetB) Q.52. Consider the following minerals:
In India, which of the above is/are officially designated as major minerals?[a) 1 and 2 only [b) 4 only [c) 1 and 3 only
[d) 2, 3 and 4 only
Difficulty : Tough 🥵 These are lesser known minerals.
Type: Contemporary 📅
- Chromite(#2) is a metallic mineral and metallic mineral are mostly in the major mineral category. So, We are 50:50 between A or D.
- According to official sites of the ministry of mines 2,3 and 4 are listed as major minerals. → Correct answer is D
(Pre’20-SetB) Q.56. Siachen Glacier is situated to the[a) East of Aksai Chin [b) East of Leh [c) North of Gilgit
[d) North of Nubra Valley
Difficulty : Tough 🥵 Difficult to memorize and recall the relative locations of all the glaciers. साला इतने डिटेल मे कौन पढ़ता है?
Type: Theory 📚
- 2019: The Defence Minister announced the Siachen area will be opened for tourists. It is situated to the north of Nubra Valley so the correct answer is “D”.
- I’m not labelling ‘School Atlas’ as source because A) either not given or B) not possible to memorize and recall.
(Pre’20-SetB) Q.78. Consider the following pairs
River – Flows into
- Mekong — Andaman Sea
- Thames — Irish Sea
- Volga — Caspian Sea
- Zambezi — Indian Ocean
Which of the pairs given above is/are correctly matched?[a) 1 and 2 only [b) 3 only
[c) 3 and 4 only[d) 1, 2 and 4 only
Difficulty : Medium 🧐 Volga-Caspian Sea pair is given in NCERT. Others require command over the world map.
Type: Theory 📚
- Volga is one of the most important rivers of Russia. It provides a navigable waterway of 11,200 km and drains into the Caspian Sea. → #3 is right, We are 50:50 between B or C.
- Zambezi either crosses or forms the boundaries of six countries—Angola, Zambia, Namibia, Botswana, Zimbabwe, and Mozambique and finally drains in Indian Ocean.
- Mekong forms part of the international border between Myanmar (Burma) and Laos, as well as between Laos and Thailand. The river then flows through Laos, Cambodia, and Vietnam before draining into the South China Sea. So, #1 is wrong.
- Thames River drains into North sea So, #2 is wrong.
- NCERT Fundamentals of Human Geography Page 76- Mentions about the Volga so helps arriving at 50:50 between B or C. Then you have to check world map for the other rivers!
- Rajtanil’s World geography Youtube lecture series Lecture Ref1: @ 42 Volga
- Lecture Ref2 @4:00 African Rivers
- School Atlas.
