UPSC Civil Services GK Questions 2026

Static general knowledge is six of the seven lines of the General Studies Paper-I syllabus in the UPSC CSE notice: History of India and the Indian National Movement; Indian and World Geography; Indian Polity and Governance; Economic and Social Development; Environmental Ecology, Bio-diversity and Climate Change; and General Science. The Commission tests understanding rather than recall, through statements to be judged correct or incorrect, pairs to be matched and assertion-reason items, and it likes the edges of a topic: a lesser-known provision of the Constitution, a river's tributary, a species' conservation status, the mandate of a statutory body. This page holds GK24's topic-wise GK notes for UPSC, written as short facts and tables, in English and Hindi, with each note linked to the current affairs and previous-year questions on the same topic. Start with Polity and Modern History, which carry the most questions, then Geography, the Economy, Environment, Ancient and Medieval culture and Science. Read a note, solve its PYQs, take its quiz, and come back to it in your monthly revision. A candidate who knows these notes and reads the daily current affairs has covered the syllabus the notice prescribes for Paper-I.

UPSC Civil Services GK Questions with Answers

Q10102.Indian EconomyHard

Which of the following correctly defines the primary deficit?

  1. A.Fiscal deficit minus interest payments
  2. B.Revenue expenditure minus revenue receipts
  3. C.Total expenditure minus total receipts including borrowings
  4. D.Revenue deficit minus grants for creation of capital assets
Show answer
Correct answer: A. Fiscal deficit minus interest payments

The fiscal deficit of a year contains the cost of servicing past borrowing as well as fresh spending, so taking out interest payments leaves the primary deficit, which shows how far the present year's expenditure exceeds its receipts on its own account.

Q10103.Indian EconomyMedium

Gross National Product is obtained by

  1. A.Adding net factor income from abroad to Gross Domestic Product
  2. B.Subtracting depreciation from Gross Domestic Product
  3. C.Adding indirect taxes to Net National Product
  4. D.Dividing Gross Domestic Product by the population
Show answer
Correct answer: A. Adding net factor income from abroad to Gross Domestic Product

Gross domestic product counts what is produced inside the domestic territory, whoever produces it, while gross national product counts what is produced by the normal residents of the country, wherever they are; the bridge between them is net factor income from abroad, which is the income Indians earn abroad minus…

Q10106.Indian EconomyAsked in: SSC CGL · 03 Dec 2022, Shift 4Medium

Unemployment arising due to mismatch between job availability in the market and skills of available worker is called

  1. A.Seasonal
  2. B.Structural
  3. C.Economical
  4. D.Frictional
Show answer
Correct answer: B. Structural

It arises when the structure of the economy changes, so that the jobs being created need skills different from those the available workers possess; it lasts long and is cured by retraining and education rather than by a revival of demand.

Q10107.Indian EconomyAsked in: UPSC Civil Services · UPSC Civil Services (Prelims) Official PMedium

Disguised unemployment generally means

  1. A.large number of people remain unemployed
  2. B.alternative employment is not available
  3. C.marginal productivity of labour is zero
  4. D.productivity of workers is low
Show answer
Correct answer: C. marginal productivity of labour is zero

Disguised unemployment, also called hidden unemployment, exists where more persons are engaged in a job than are actually needed, so withdrawing one of them would not reduce output at all; that worker's marginal contribution is therefore zero.

Q10109.GeographyHard

Why is the tide generating force of the moon greater than that of the sun?

  1. A.The moon is more massive than the sun
  2. B.The tide generating force varies inversely with the cube of the distance, and the moon is much nearer
  3. C.The moon revolves in the same direction as the earth rotates
  4. D.The moon has no atmosphere
Show answer
Correct answer: B. The tide generating force varies inversely with the cube of the distance, and the moon is much nearer

The tide generating force of a body is not simply its gravitational pull but the difference in that pull across the earth, and that difference falls off as the cube of the distance rather than the square.

Q10113.GeographyMedium

The highest tidal range in the world is recorded at

  1. A.The Gulf of Kutch
  2. B.The Bay of Fundy
  3. C.The Strait of Gibraltar
  4. D.The Gulf of Mexico
Show answer
Correct answer: B. The Bay of Fundy

The correct answer is B, the Bay of Fundy, between Nova Scotia and New Brunswick in Canada, where the funnel shape of the bay and the length of the inlet make the incoming tide pile up to a range of the order of fifteen to sixteen metres.

Q10114.GeographyEasy

Spring tides occur on which days of the lunar month?

  1. A.First and third quarter of the moon
  2. B.New moon and full moon
  3. C.Only full moon
  4. D.Only new moon
Show answer
Correct answer: B. New moon and full moon

On these days the sun, the moon and the earth lie in a straight line, a position called syzygy, so the pulls of the sun and the moon act together and the tidal range is at its greatest; spring tides therefore occur twice in a lunar month and have nothing…

Q10115.GeographyEasy

Which division of the ocean floor is the most important economically, holding the richest fishing grounds and most offshore petroleum?

  1. A.Continental shelf
  2. B.Continental slope
  3. C.Abyssal plain
  4. D.Oceanic trench
Show answer
Correct answer: A. Continental shelf

It is the gently sloping, shallow margin of the continent, extending to a depth of about 200 metres with a gradient of one degree or less and an average width of about seventy to eighty kilometres, and it makes up roughly 7.5 per cent of the ocean area.

Q10117.GeographyAsked in: Delhi · 6th Sep 2021, Shift 3Medium

With reference to the latitudinal distribution of salinity in the oceans, which of the following statements is correct?

I. The highest salinity is recorded in the equatorial regions.
II. The salinity of the oceans of the Northern Hemisphere is higher than that of the Southern Hemisphere.

  1. A.Neither I nor II
  2. B.Both I and II
  3. C.Only I
  4. D.Only II
Show answer
Correct answer: D. Only II

Statement I is wrong because the equatorial belt receives very heavy rainfall and has high cloud cover, so the surface water there is diluted; the highest salinity in the open ocean is recorded in the subtropical high pressure belts, roughly between twenty and thirty degrees of latitude, where skies are…

Q10119.General ScienceHard

The viscosity of a liquid and the viscosity of a gas behave in which way when the temperature is raised?

  1. A.Both increase
  2. B.Both decrease
  3. C.Viscosity of the liquid decreases and that of the gas increases
  4. D.Viscosity of the liquid increases and that of the gas decreases
Show answer
Correct answer: C. Viscosity of the liquid decreases and that of the gas increases

In a liquid, viscosity comes chiefly from cohesion between molecules; heating weakens that cohesion, so the layers slide past one another more easily and the viscosity falls, which is why engine oil becomes thinner as the engine warms and why honey flows freely when it is warmed.

Q10120.General ScienceEasy

The spherical shape of a small liquid drop is due to

  1. A.Viscosity
  2. B.Surface tension
  3. C.Capillarity
  4. D.Buoyancy
Show answer
Correct answer: B. Surface tension

Cohesive forces pull the molecules at the surface of a liquid inward, so the surface behaves like a stretched membrane and takes the smallest area that can enclose the given volume; for a fixed volume the shape of least surface area is a sphere, which is why a free drop…
