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 Geography subject. Same as last year five questions asked
– 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 River prem resurfaced
– 2019: Glacier vs river pair question asked. One question about Glacier map location Glacier prem not resurfaced.
There had been a trend of asking about particularly Vulnerable Tribal Groups (PVTGs) every few years. Not seen in this time Not seen this time
– 2019: 5 out of 7 Geography MCQs are based on maps. – 2 out of 5 Geography MCQs Based on maps 3 out of 5 MCQ were 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. Mineral prem is resurfaced this year.
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 1 MCQ about Ocean temperature.
Occasional questions about world geography map Worldmap based question on river basin Nothing.

10 Comments on “[AnswerKey] UPSC Prelims-2021: Geography MCQs Solved with Explanation for All Sets & Strategy for 2022”

  1. For [CSP21-SET-C] Q.48)

    The answer is a) 1 only

    In the temperate zone, westerlies make the eastern sections of oceans warm. But not warmer than the western sections.

    Because the eastern sections receive cold currents from the north. The temperature of eastern waters is less than the western waters. Rember the desert formation on the western parts of the continents?

    1. Maam how can Eastern section receive current from polar areas there are polar easterlies which displaces the water to western side. What is in answer key

    2. increase in temperature is directly proportional to the down-welling of water. the westerlies drag water from the eastern margin to the western margin so, the water gets accumulated on the western margin, this excess of water exerts pressure downward and down-welling of water take place there.

    3. I think the confusion is about the direction, as in which part is eastern section and which part is western? everyone is using the same information and that too correctly, but In this question i think eastern/western part is in reference to ocean and not in reference to continent. So, for example in Antarctic, eastern section is europe side and western section is near America.

  2. Answer of question 43 will be chanab river because after merger of satluj and chenab,the river name is chenab. I see it on Google map.
    And according to ncert book chenab is longest river.
