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.
Which one of the following sedimentary rocks is organically formed?
Chalk is a soft, white limestone built up from the tiny calcium carbonate shells of marine micro-organisms, so it is an organically formed sedimentary rock.
Read the full explanation →Which one of the following is the natural vegetation of South east China ?
South-east China has a warm, humid subtropical climate with rain in every season, and its natural vegetation is broadleaf evergreen forest of the subtropics.
Read the full explanation →Girth of stem of a plant increases due to division of cells in
The girth, or thickness, of a stem increases only through the lateral meristems, the vascular cambium and the cork cambium.
Read the full explanation →Which one of the following statements with respect to Global Positioning System (GPS) is not correct?
This statement is false: GPS was built by the United States for its military, but it has been open to civilian users worldwide for decades.
Read the full explanation →The protein-digesting enzyme secreted by the stomach wall in case of mammals is called
The gastric glands in the stomach wall secrete pepsin, which begins the digestion of proteins into smaller peptides. The chief cells of the gastric glands release pepsin in an inactive form, pepsinogen.
Read the full explanation →Copper sulphate crystals available in the market are blue coloured crystals. By careful heating, they turn to white colour. Which one of the following is responsible for the blue colour?
The blue colour comes from water of crystallisation: blue vitriol is CuSO4·5H2O, and heating drives off these five water molecules to leave white anhydrous copper sulphate.
Read the full explanation →Which one of the following metals can be extracted using carbon as reducing agent?
Zinc lies in the middle of the reactivity series, so its oxide can be reduced to the metal by heating it with carbon (coke): ZnO + C → Zn + CO.
Read the full explanation →Which of the following statements regarding Earth's internal structure is/are correct ? 1. The oceanic crust is heavier than the continental crust. 2. Most of the Earth's internal heat is contained within the mantle. 3. Large convective cells in the crust circulate heat and drive plate-tectonic processes. Select the answer using the code given below :
Statements 1 and 2 are correct, but statement 3 is wrong because the convection cells that drive plate movement lie in the mantle, not in the crust.
Read the full explanation →For Aluminium (Al) (atomic number : 13, mass number: 27), which one among the following statements is NOT correct ?
This is false: aluminium has three electrons in its outer shell and loses all three, so its valency is 3.
Read the full explanation →Cambium is an example of
Cambium lies along the sides of stems and roots and its dividing cells increase their thickness, which is the work of a lateral meristem.
Read the full explanation →Consider the following statements : I. At the equator, the Coriolis force is zero and here the winds blow perpendicular to the isobars. II. The Coriolis force is directly proportional to the angle of latitude. III. The Coriolis force and the resultant wind do not blow parallel to the isobars at higher latitudes. Which of the statements given above are correct?
Statements I and II describe the Coriolis force correctly; statement III is wrong, because away from the equator the wind ends up blowing parallel to the isobars.
Read the full explanation →Which compound, when dissolved in water, conducts electricity and forms a basic solution ?
Sodium hydroxide dissolves in water and splits completely into Na+ and OH- ions; the ions carry current and the hydroxide ions make the solution strongly basic.
Read the full explanation →Two convex lenses with power 2 dioptre are kept in contact with each other. The focal length of the combined lens system is
Powers of lenses in contact simply add, so the combination has a power of 2 + 2 = 4 dioptre, and its focal length is 1/4 m, that is 0.25 m. The power of a lens is the reciprocal of its focal length in metres, P = 1/f, and is…
Read the full explanation →Consider the following statements relating to Richter scale : 1. It was devised in 1935 by Charles F. Richter 2. It describes the quantity of energy released by a single earthquake 3. Richter Scale has no upper limit Which of the statements given above is/are correct ?
All three statements about the Richter scale are correct. Statement 1 is correct: the American seismologist Charles F. Richter devised the scale in 1935 at the California Institute of Technology, working with Beno Gutenberg.
Read the full explanation →Which one of the following land territories of Indonesia is not touched by the Equator ?
Java lies wholly in the Southern Hemisphere, roughly between 6° S and 9° S, so the Equator does not pass over it.
Read the full explanation →The duration of monsoon in India extends for an average period of
The south-west monsoon usually lasts about 100 to 120 days, from early June to about mid-September. The monsoon reaches the Kerala coast around 1 June and spreads over almost the whole country by early to mid-July.
Read the full explanation →At which one of the following places was a Shiva temple not constructed under the patronage of the Chola rulers?
Naneghat is a mountain pass in the Western Ghats of Maharashtra, known for Satavahana cave inscriptions, not for a Chola Shiva temple.
Read the full explanation →Which one of the following tissues is known as basic packing tissue and found in xylem and phloem ?
Parenchyma is the basic packing tissue of plants, and it is also present in both xylem (xylem parenchyma) and phloem (phloem parenchyma).
Read the full explanation →While watching news, you hear about a place, of which you had never heard of earlier. You want to know more about the place and you want to locate it on the map. Which of the following is/are required for you to be able to locate the place on the map?
A point on a map is fixed where its line of latitude crosses its line of longitude, so both values are needed and enough.
Read the full explanation →Which among the following is the correct arrangement of halogens in the increasing order of their oxidizing nature ?
Oxidising power of the halogens falls as we go down group 17, so iodine is the weakest and fluorine the strongest oxidising agent.
