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.
How many hours in advance is a pre-cyclone watch, the first stage of the India Meteorological Department warning, issued?
The warning comes in four stages, each tied to a number of hours before the adverse weather is expected on the coast.
Read the full explanation →Which body names the tropical cyclones of the north Indian Ocean?
The names themselves are contributed by the thirteen member countries of the panel, but the centre at New Delhi, which the India Meteorological Department runs, takes the next name from the list, announces it when a deep depression strengthens into a cyclonic storm, and issues advisories to all the member…
Read the full explanation →In which year did the naming of tropical cyclones in the north Indian Ocean begin?
The eight countries of the WMO and ESCAP Panel on Tropical Cyclones agreed on a list of names for this basin and began using them in 2004, long after the Atlantic, where naming had been practice for decades.
Read the full explanation →According to the India Meteorological Department, a system is classified as a super cyclonic storm when the sustained wind speed is at least
The India Meteorological Department puts a system in the highest class, super cyclonic storm, when the sustained wind at its centre reaches 222 km/h, which is 120 knots.
Read the full explanation →What is the minimum sea surface temperature generally required for a tropical cyclone to form?
A tropical cyclone runs on the latent heat released when water vapour condenses, so it needs a sea whose surface is at about 26.5 degrees Celsius or warmer, with that warm water reaching down about fifty metres, so that the churning of the sea does not cool the surface.
Read the full explanation →A cyclone is known by different names in different parts of the world. In Philippines it is called as _______.
The Philippines lies in the western North Pacific, and every tropical cyclone of that basin, whether it strikes the Philippines, China or Japan, is called a typhoon.
Read the full explanation →Which of the following pairs are the primary lymphoid organs of the human body?
These are the organs in which lymphocytes are produced and in which they mature into cells able to tell self from non-self; the B cells complete this training in the bone marrow and the T cells in the thymus, a gland behind the breastbone that shrinks with age.
Read the full explanation →Which of the following is a live attenuated vaccine?
The correct answer is B, the oral polio vaccine, which contains live poliovirus weakened so that it can multiply in the gut and raise immunity without causing the disease; it is the vaccine given as two drops in the pulse polio rounds.
Read the full explanation →The immunity a newborn gets from its mother's milk is an example of
The antibodies, mainly of the IgA class, come ready-made in the first milk, the colostrum, and the child's own immune system does no work, which is why the protection begins at once and lasts only a few months; antibodies of the IgG class reach the foetus through the placenta in…
Read the full explanation →Antibodies in the human body are produced by
On meeting an antigen a B lymphocyte multiplies and turns into a plasma cell, which pours out antibodies, that is immunoglobulins, into the blood; this arm of the defence is called humoral immunity, while T lymphocytes kill infected cells and regulate the response in cell-mediated immunity.
Read the full explanation →The BCG vaccine gives protection against
BCG stands for Bacillus Calmette-Guerin, a live but weakened strain of the bovine tuberculosis bacterium, and in India it is given soon after birth under the Universal Immunisation Programme, mainly to prevent the severe forms of childhood tuberculosis.
Read the full explanation →Edward Jenner is remembered for developing a vaccine against which disease?
In 1796 Edward Jenner used matter from a cowpox sore to protect a boy against smallpox, the first vaccination in the modern sense, and the word vaccine comes from vacca, the Latin for cow.
Read the full explanation →Which vitamin is essential for the clotting of blood?
The liver needs vitamin K to make prothrombin and several other clotting factors, so a deficiency of it lengthens the clotting time and causes bleeding; this is why a newborn is given vitamin K and why the vitamin is sometimes called the anti-haemorrhagic vitamin.
Read the full explanation →The Rh factor in human blood is named after
Landsteiner and Wiener found the antigen in 1940 while working with the blood of the rhesus monkey, and the first two letters of rhesus gave the factor its name; a person with the D antigen on the red cells is Rh positive and one without it is Rh negative.
Read the full explanation →A person of which blood group has no antibody in the plasma and is therefore the universal recipient?
A person of group AB carries both the A and the B antigen on the red cells, and because the body does not make antibodies against its own antigens, the plasma carries neither anti-A nor anti-B; blood of any group can therefore be transfused into such a person, who is…
Read the full explanation →Which blood group is called the universal donor?
The red cells of group O carry neither the A antigen nor the B antigen, so when they are transfused the antibodies in the recipient's plasma find nothing to bind to and the cells are not destroyed, which is why group O, and strictly O negative, can be given to…
Read the full explanation →Who discovered the ABO system of blood groups?
The correct answer is A, Karl Landsteiner, the Austrian physician who found in 1900 that human blood falls into groups according to the antigens on the red cells, which made safe transfusion possible, and who received the Nobel Prize in Physiology or Medicine for it in 1930; with Wiener he…
Read the full explanation →Which one of the following types of radiation has the shortest wavelength?
Of the four, ultraviolet lies furthest towards the short-wavelength, high-energy end of the electromagnetic spectrum. All electromagnetic waves travel at the speed of light in vacuum, but they differ in wavelength and frequency.
Read the full explanation →In the human body, blood flows through a process of double circulation. Which one of the following statements is true in this regard?
The pulmonary veins carry oxygen-rich blood from the lungs into the left atrium. In double circulation, blood passes through the heart twice in each full round.
Read the full explanation →School bells are made of metals because metals are
Metals produce a ringing sound when struck, a property called sonority, which is why bells are made of metal. Sonorous means 'producing a deep, ringing sound'.
