Static GK decides most of the General Awareness score in SSC exams. The CGL, CHSL and CPO notices describe it in almost the same words: questions on India and its neighbouring countries in History, Culture, Geography, the Economic Scene, General Policy and Scientific Research, and on everyday observation in its scientific aspect. The GD notice adds Sports, General Polity and the Indian Constitution, and the MTS notice lists Social Studies, General Science and Environmental Studies up to the 10th Standard. This page brings together GK24's GK notes and practice questions tagged for all five SSC exams. The notes follow a subject-wise syllabus, one topic per note in English and Hindi: Indian Polity, Indian History, Geography, Indian Economy, General Science, Environment and Ecology, Art and Culture, Computer, Sports, Awards and Honours, Books and Authors, Days and Dates, and Static GK. Each note is written as short facts and tables so that a topic can be revised in one sitting, and each ends with multiple-choice questions and explanations. The level is what changes between exams: read MTS and GD topics at Class 10 depth, CHSL at Class 12 depth, and CGL and CPO at graduate depth, where questions ask for the article number or the year rather than the broad idea. Start with Polity, History and Geography, which fill the most questions in past papers in GK24's reading, then move to the Economy and Science. After each note, solve its questions here and your exam's previous-year questions on its own page.

Its Target 13 calls for real measures to ensure that the gains from using genetic resources, digital sequence information and the traditional knowledge tied to them are shared fairly and equitably, which is exactly what India’s benefit-sharing payments to State Biodiversity Boards do.
Read the full explanation →Which state received the largest share of the access and benefit-sharing amount distributed by the National Biodiversity Authority?
Shares were not handed out equally: the National Biodiversity Authority used an area-based method, so a state’s portion grew with the geographical spread of the crops concerned and the land under them, read off the Unified Portal for Agricultural Statistics of the Ministry of Agriculture and Farmers Welfare.
Read the full explanation →Under which Act does India’s access and benefit-sharing (ABS) mechanism operate?
India’s access and benefit-sharing framework is governed by this Act, as amended in 2023, along with the Biological Diversity Rules, 2024, and the Access and Benefit-Sharing Regulations, 2025.

Explaining what real-time source apportionment means, Dr Jitendra Singh pointed to a screen showing that at that moment transport was contributing roughly 25 per cent of the air pollution in Delhi, while the overall pollution level stood at around 180.
Read the full explanation →At what spatial resolution, and for how long ahead, does the AIRWISE system linked with AATAL forecast air quality?
AIRWISE, the Air Quality Warning and Integrated Decision Support System for Emissions, issues air-quality forecasts at a spatial resolution of 400 metres for the following 72 hours.
Read the full explanation →Under which mission has the AATAL air pollution analysis laboratory for Delhi NCR been established?
The laboratory has been established under Mission Mausam, announced by Prime Minister Narendra Modi, to deepen the scientific understanding of atmospheric pollution and to supply usable evidence for managing air quality in Delhi NCR.

That is the full form of AATAL, the facility inaugurated for Delhi NCR by Dr Jitendra Singh at the Delhi branch of the Indian Institute of Tropical Meteorology.
Read the full explanation →Which one of the following is an example of the force of gravity of the earth acting on a vibrating pendulum bob?
For a swinging pendulum, the component of the bob's weight along its path always pulls it back towards the lowest point, so gravity acts as a restoring force.
Read the full explanation →Shoots of plant show upward movement and it can be designated to be
A shoot grows upward, away from the pull of gravity, so it is negatively geotropic. A tropism is a directional growth movement of a plant part in response to a stimulus: towards the stimulus is positive, away from it is negative.
Read the full explanation →An iron nail sinks in water whereas an iron ship floats. Which of the following statements is correct in this regard?
1. Average density of ship is greater than that of the water
2. Average density of iron nail is greater than that of the water
3. Average density of the ship is less than that of the water
4. Average density of the ship is equal to that of the water
Select the correct answer using the code given below:
An object floats when its average density is less than that of the liquid and sinks when it is greater.
Read the full explanation →Which of the following statements about specific heat of a body is/are correct?
1. It depends upon mass and shape of the body
2. It is independent of mass and shape of the body
3. It depends only upon the temperature of the body
Select the correct answer using the code given below:
Specific heat is a property of the material, not of the size or shape of the particular body. It is the amount of heat needed to raise the temperature of unit mass (1 kg or 1 g) of a substance by one degree.
Read the full explanation →The wavelength of X-rays is of the order of
X-rays have wavelengths of roughly 0.01 to 10 nanometres, and a typical value is about one ångström (1 Å = 10⁻¹⁰ m = 0.1 nm).
Read the full explanation →Which one of the following substances is NOT a mixture?
Ice is simply water in its solid state, a single compound with the fixed formula H2O, so it is a pure substance, not a mixture.
Read the full explanation →Liquid vegetable oils are converted to solid margarine by the use of
Vegetable oils are hardened into margarine and vanaspati ghee by hydrogenation. Liquid vegetable oils are unsaturated: their fatty-acid chains contain carbon-carbon double bonds.
Read the full explanation →Which one of the following is the correct arrangement of metals in the decreasing order of their reactivity?
This matches the reactivity series, which lists metals from the most to the least reactive. Sodium is near the top: it reacts violently with cold water and is stored under kerosene.
Read the full explanation →Which one of the following salts is responsible for temporary hardness of water?
Temporary hardness is caused by the bicarbonates (hydrogencarbonates) of calcium and magnesium dissolved in water. It is called temporary because it can be removed simply by boiling: on heating, the soluble bicarbonates break down into insoluble carbonates, or magnesium hydroxide, which settle out, and carbon dioxide escapes.
Read the full explanation →Which one of the following will NOT produce carbon dioxide on reacting with an aqueous solution of hydrochloric acid?
Quick lime is calcium oxide (CaO), which contains no carbonate, so it gives no carbon dioxide with an acid. Acids release carbon dioxide only from carbonates and hydrogencarbonates: the general reaction is metal carbonate plus acid gives salt, water and carbon dioxide.
Read the full explanation →Common salt (NaCl) is not used as a raw material for preparation of which one of the following compounds?
Plaster of Paris is made from gypsum, not from common salt. When gypsum, calcium sulphate dihydrate (CaSO4·2H2O), is heated to about 373 K, it loses part of its water and becomes calcium sulphate hemihydrate (CaSO4·½H2O), which is Plaster of Paris; it sets hard again when mixed with water and is…
