Static GK decides the General Awareness score in SSC CHSL. Of the 25 questions in Tier-I and the 20 in Tier-II, most come from Indian Polity, History, Geography, the Economy and General Science, the areas the CHSL 2026 notice lists as History, Culture, Geography, Economic Scene, General Policy and Scientific Research relating to India and its neighbouring countries. The level is that of Class 12, so the questions are direct: which article, which river, which ruler, which year. Polity asks about parts and schedules of the Constitution, fundamental rights, the President, Parliament, the Supreme Court and constitutional bodies. History covers the Indus Valley, the Mauryas and Guptas, the Sultanate and Mughal periods, 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 with everyday applications, and Culture covers dances, festivals, monuments and books. This page holds GK24's topic-wise GK notes for SSC CHSL, 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.
The Tapi river originates near which place in Madhya Pradesh?
It is the second of the two large west flowing peninsular rivers and runs almost parallel to the Narmada, with the Satpura range between them.
Read the full explanation →The Narmada river rises from which of the following?
The correct answer is A, the Amarkantak plateau in Madhya Pradesh, where the Narmada rises at about one thousand metres and begins its westward journey of some thirteen hundred kilometres through Madhya Pradesh and Gujarat to the Gulf of Khambhat; on the way it makes the Dhuandhar falls and the…
Read the full explanation →Which of the following Indian rivers does not form a delta at its mouth?
It flows west through the narrow rift between the Vindhya and the Satpura ranges and opens into the Gulf of Khambhat, where strong tides sweep away the silt, so the river ends in a funnel shaped estuary and not a delta; the Tapi, which also flows west in a rift…
Read the full explanation →The Indus, the Satluj and the Brahmaputra cut deep gorges across the Himalaya because they are older than the present mountains. Such drainage is called
These rivers were flowing when the Himalaya was still rising, and instead of being turned aside they cut downward as fast as the land rose, leaving the gorges of the Indus near Gilgit, of the Satluj at Shipki and of the Brahmaputra at the great bend in the Dihang.
Read the full explanation →Centripetal drainage, in which streams flow inward from all sides, is best illustrated in India by the streams draining into
Loktak lies in the floor of the Manipur valley, which is ringed by hills, so the streams of the valley run inward into it from every side, the classic shape of a centripetal pattern; the lake is also known for its floating phumdis and for Keibul Lamjao, the only floating…
Read the full explanation →Which river of peninsular India is known as the Dakshin Ganga and has the largest basin in the peninsula?
It rises at Trimbakeshwar in Nashik district of Maharashtra, runs about one thousand four hundred kilometres across Maharashtra, Telangana and Andhra Pradesh to the Bay of Bengal, and drains about 3.1 lakh square kilometres, the largest catchment in the peninsula, which is why it is called the Ganga of the…
Read the full explanation →Which is the largest river basin of India by area?
The correct answer is C, the Ganga basin, which covers about 8.6 lakh square kilometres inside India, close to a quarter of the country, and takes in parts of Uttarakhand, Uttar Pradesh, Madhya Pradesh, Bihar, Jharkhand, West Bengal, Haryana, Himachal Pradesh, Chhattisgarh, Rajasthan and Delhi.
Read the full explanation →The Narmada, the Son and the Mahanadi flowing out in different directions from the Amarkantak plateau is an example of which drainage pattern?
In a radial pattern the streams start from a dome, a volcanic cone or a high plateau and run outward in all directions like the spokes of a wheel.
Read the full explanation →The drainage pattern in which the tributaries of a river look like the branches of a tree is called
The word comes from the Greek for tree, and the pattern develops where the underlying rock is of uniform hardness and the slope is gentle, so the streams branch freely without being guided by lines of weakness; the tributaries of the Ganga in the northern plain are the standard Indian…
Read the full explanation →Equal volumes of all gases, under the same conditions of temperature and pressure, contain an equal number of molecules. This statement is known as
It is the reason one mole of every gas occupies the same 22.4 litres at standard temperature and pressure, and it allowed chemists to settle the formulae of gases such as hydrogen and oxygen as having two atoms each.
Read the full explanation →Carbon forms two oxides, carbon monoxide and carbon dioxide, in which twelve grams of carbon combines with sixteen grams and thirty two grams of oxygen respectively. This illustrates
When two elements form more than one compound, the masses of one element that combine with a fixed mass of the other bear a simple whole number ratio, and here the oxygen masses of sixteen and thirty two grams for the same twelve grams of carbon are in the ratio…
Read the full explanation →How many moles are present in 36 grams of water?
The molecular mass of water is eighteen unified atomic mass units, two hydrogen atoms of 1 u each and one oxygen atom of 16 u, so one mole of water weighs eighteen grams.
Read the full explanation →One unified atomic mass unit, written as u, is defined as
This standard was adopted so that the atomic masses of all elements could be compared on one relative scale, and on it hydrogen comes out as about 1 u, oxygen as 16 u and chlorine as 35.5 u. Option A is wrong because the hydrogen atom was the standard in…
Read the full explanation →At standard temperature and pressure, the volume occupied by one mole of any gas is
It follows from Avogadro's law: since equal volumes of all gases at the same temperature and pressure contain an equal number of molecules, one mole of hydrogen, of oxygen or of carbon dioxide all take up the same space at standard temperature and pressure, even though their masses are two…
Read the full explanation →The number of particles present in one mole of any substance is
It is the number of atoms in twelve grams of carbon twelve, and it holds for atoms, molecules, ions or electrons alike, so one mole of water has that many water molecules and one mole of sodium has that many sodium atoms.
Read the full explanation →The formula unit mass of CaCl2 is:
Calcium chloride is an ionic compound, so the sum of the atomic masses in its formula is called the formula unit mass rather than the molecular mass.
Read the full explanation →Atomic mass of Nitrogen is 14 and that of Hydrogen is 1. What will be the molecular mass of Ammonia?
The formula of ammonia is NH3, so its molecular mass is the atomic mass of one nitrogen atom added to the atomic masses of three hydrogen atoms, that is fourteen plus three times one, which equals seventeen unified atomic mass units; one mole of ammonia therefore weighs seventeen grams.
Read the full explanation →The law which states that a pure chemical compound always contains the same elements combined in the same proportion by mass is known as
Water drawn from a river, from rain or made in a laboratory always has hydrogen and oxygen in the mass ratio of one to eight, and ammonia always has nitrogen and hydrogen in the ratio of fourteen to three.
Read the full explanation →The law of conservation of mass in a chemical reaction was given by
The correct answer is B, Antoine Lavoisier, the French chemist who showed by careful weighing in closed vessels that the total mass of the products of a reaction is exactly equal to the total mass of the reactants, so that matter is neither created nor destroyed in a chemical change.
Read the full explanation →The Desert Festival of Rajasthan is held at which place?
The Desert Festival is held at Jaisalmer in the month of Magh, in the cool season, with camel races, turban tying competitions, folk music and dance in the sands near the Sam dunes, and it is among the best known tourism events of the state.
