Defence GK Questions 2026

Static GK carries most of the General Knowledge marks in the defence exams, and science carries the largest share of it. In NDA & NA, Physics, Chemistry and General Science are about half of the 400 marks of Part B, and History, the freedom movement and Geography are about 20% each, as per the notice. In the CDS (II) 2026 General Knowledge paper, GK24 counted about 37 science questions, about 20 each on Polity and History, about 15 on Geography and environment and about 10 on the Economy; this count is guidance, not an official break-up. The Army's Agniveer CEE gives 15 of its 50 General Duty questions to General Knowledge and 15 to General Science, which covers cells, the human body, plants and animals and common epidemics. Its GK list names history, culture and geography of India and its neighbours, the Constitution, inventions and discoveries, books and authors, and the Indian Armed Forces. This page holds GK24's topic-wise GK notes and GK questions tagged for NDA, CDS and Agniveer, in English and Hindi: General Science, Indian History, Art and Culture, Indian Polity, Geography, Indian Economy and Static GK. Read one topic at a sitting, then solve its questions and the previous-year questions of your exam to see what stayed with you.

Q1742.General ScienceAsked in: NDA · NDA-I 2023, GATEasy

Which among the following is the popular method for manufacture of ammonia ?

  1. A.Ostwald's process
  2. B.Haber-Bosch process
  3. C.Electric furnace process
  4. D.Electrolysis process
Show answer
Correct answer: B. Haber-Bosch process

Almost all the world's ammonia is made by combining nitrogen and hydrogen directly in this process. In the Haber-Bosch process, nitrogen from the air and hydrogen, usually obtained from natural gas, are made to react in the ratio 1 to 3.

Q1743.GeographyAsked in: NDA · NDA-I 2024, GATMedium

Which of the following statements regarding cyclones and anti-cyclones is/are correct ? 1. In the Northern Hemisphere, cyclones rotate counter clockwise and anticyclones rotate clockwise. 2. Cyclones are often associated with cloudy or rainy weather, whereas anticyclones are often associated with fair weather. 3. In the Southern Hemisphere, the cyclonic spiral will be clockwise because the Coriolis force acts to the left. Select the answer using the code given below :

  1. A.1 only
  2. B.1 and 2 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: D. 1, 2 and 3

All three statements follow from how the Coriolis force turns winds around low and high pressure. A cyclone is a low-pressure centre into which winds blow, and an anticyclone is a high-pressure centre from which winds blow out.

Q1746.General ScienceAsked in: NDA · NDA-II 2025, GATMedium

Which one of the following is an endothermic reaction ?

  1. A.CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g)
  2. B.C6H12O6 (aq) + 6O2 (g) → 6CO2 (g) + 6H2O (l)

Show answer
Correct answer: D. 2Pb(NO3)2 (s) → 2PbO (s) + 4NO2 (g) + O2 (g)

Breaking lead nitrate into lead oxide, nitrogen dioxide and oxygen needs a steady supply of heat, so the reaction absorbs energy and is endothermic.
