SSC CGL GK Questions 2026

Static GK decides the General Awareness score in SSC CGL. Of the 25 questions in Tier-I and the 25 in Tier-II Paper-I, most come from Indian Polity, History, Geography, the Economy and General Science, the areas the CGL 2026 notice lists as History, Culture, Geography, Economic Scene, General Policy and Scientific Research relating to India and its neighbouring countries. Polity questions ask about articles, parts and schedules of the Constitution, amendments, the President, Parliament, the Supreme Court and constitutional bodies. History covers the Indus Valley, the Mauryas and Guptas, the Delhi Sultanate and Mughals, and the freedom struggle from 1857 to 1947. Geography asks about rivers, soils, climate, national parks, minerals and world physical features. The Economy part asks about budget terms, the RBI, banking and basic concepts. General Science is school-level Physics, Chemistry and Biology. This page holds GK24's topic-wise GK notes for SSC CGL, written as short facts and tables so a topic can be revised in one sitting. Read a topic, then solve its previous-year questions and quiz on this site to check what you retained.

SSC CGL GK Questions with Answers

Q9601.General ScienceAsked in: UPSC CAPF · CAPF 2021, Paper IMedium

An object is placed 10 cm in front of a lens. The image formed is real, inverted and of same size as the object. What is the focal length and nature of the lens?

  1. A.5 cm, converging
  2. B.10 cm, diverging
  3. C.20 cm, converging
  4. D.20 cm, diverging
Show answer
Correct answer: A. 5 cm, converging

A real, inverted image of the same size forms only when the object sits at twice the focal length of a convex lens, so 2f = 10 cm and f = 5 cm.

Which one of the following statements with regard to greenhouse effect is correct?

  1. A.It can take place inside a glass chamber where no radiation can pass into it or pass back through it
  2. B.It can take place inside a glass chamber where long wavelength infrared radiation can pass through into it and short wavelength infrared radiation cannot pass back through it
  3. C.It can take place inside a glass chamber where short wavelength infrared radiation can pass through into it and long wavelength infrared radiation cannot pass back through it
  4. D.It can take place inside a glass chamber where all infrared radiation can pass into it or pass back through it
Show answer
Correct answer: C. It can take place inside a glass chamber where short wavelength infrared radiation can pass through into it and long wavelength infrared radiation cannot pass back through it

Sunlight reaching a glasshouse is mostly visible light and short-wavelength (near) infrared, which glass transmits easily. The plants and soil inside absorb it, warm up and re-radiate the energy as long-wavelength infrared, because cooler bodies emit at longer wavelengths.
