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 type of seismic wave is recorded first on a seismograph?
P waves are longitudinal, moving the particles of the medium back and forth along the direction of travel by compression and rarefaction.
Read the full explanation →Which volcano is popularly known as the Lighthouse of the Mediterranean?
Stromboli is a small island volcano in the Lipari or Aeolian group north of Sicily, and it has been in almost continuous mild eruption for centuries.
Read the full explanation →Mount Vesuvius, the volcano whose eruption buried the city of Pompeii, is located in which country?
Mount Vesuvius stands near the Bay of Naples in southern Italy and its eruption in 79 CE buried the Roman towns of Pompeii and Herculaneum under ash, preserving them so well that they became an archaeological record of Roman daily life.
Read the full explanation →The instrument used to record the waves produced by an earthquake is called a
A seismograph carries a mass that stays nearly still while the ground and the frame move under it, and the relative motion is traced as a wavy line.
Read the full explanation →Barren Island, the only active volcano in India, is located in which of the following?
Barren Island lies in the Andaman Sea, to the east of the main Andaman group, and is the only active volcano in India and in South Asia.
Read the full explanation →The Richter scale is used to measure which of the following?
The Richter scale, devised by Charles F. Richter in 1935, expresses the energy released at the source of the shock.
Read the full explanation →The point inside the earth where an earthquake originates is known as the
The focus, also called the hypocentre, is the point below the surface at which the strained rock ruptures and releases its stored elastic energy as seismic waves.
Read the full explanation →Which of the following seismic waves cannot travel through liquids?
Secondary or S waves are transverse, so the particles of the medium move at right angles to the direction of travel.
Read the full explanation →An astronaut inside a spacecraft orbiting the earth feels weightless because
In orbit the gravitational pull of the earth is the very force that keeps the craft curving around the planet, and the craft, the astronaut and everything inside accelerate towards the earth at the same rate.
Read the full explanation →The pressure exerted by a liquid at a point inside it does not depend upon
The pressure at a point inside a liquid equals the depth multiplied by the density of the liquid and by the acceleration due to gravity.
Read the full explanation →The universal gravitational constant G was first measured experimentally by
In 1798 Cavendish used a delicate torsion balance to measure the extremely small attraction between lead spheres in a laboratory and from it obtained a value of G, about 6.674 times ten to the power minus eleven newton metre squared per kilogram squared.
Read the full explanation →A barometer is used to measure which of the following?
A mercury barometer balances the pressure of the atmosphere against a column of mercury, which stands about 76 centimetres high at sea level.
Read the full explanation →The weight of a body on the surface of the moon is about how much of its weight on the surface of the earth?
Weight equals mass times the acceleration due to gravity, and the acceleration due to gravity on the moon is about one-sixth of its value on the earth because the moon has a much smaller mass and a smaller radius.
Read the full explanation →The upward force experienced by a body immersed in a fluid is equal to the weight of the fluid displaced by it. This statement is known as
It states that a body immersed wholly or partly in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced, so the apparent loss in weight of the body equals the weight of the displaced fluid.
Read the full explanation →Hydraulic brakes used in automobiles work on which principle?
Pascal's law states that pressure applied to an enclosed fluid is transmitted undiminished in every direction to all parts of the fluid and to the walls of the container.
Read the full explanation →The escape velocity from the surface of the earth is approximately
Escape velocity is the minimum speed a body must be given so that it leaves the gravitational pull of the planet and never returns.
Read the full explanation →The value of acceleration due to gravity on the earth is maximum at which of the following?
The earth is flattened at the poles, so the distance from the centre is least there, and since g varies inversely as the square of that distance, g is largest at the poles.
Read the full explanation →What is the SI unit of pressure?
Pressure is thrust per unit area, so its unit is one newton per square metre, and this unit is named the pascal after Blaise Pascal.
Read the full explanation →Sambhar Lake, a Ramsar site in Rajasthan, is known as
Sambhar Lake lies west of Jaipur in Rajasthan, has no outlet to the sea and loses water only by evaporation, so salts brought in by seasonal streams accumulate in it.
Read the full explanation →The Montreux Record, maintained under the Ramsar Convention, is a register of
The Montreux Record names sites already on the Ramsar list where the ecological character has changed, is changing or is likely to change because of pollution, drainage, encroachment or other human interference.
