SSC GK Questions 2026

Statement I is right: commercial paper is an unsecured money market instrument issued in the form of a promissory note, so it is backed only by the credit standing of the issuer and not by any security.

It is defined purely in terms of rainfall: a significant deficiency of precipitation over an area compared with its long-period average, and it is the first stage from which the other kinds of drought follow.

It maintains forecasting stations on the major rivers and issues level and inflow forecasts to the State authorities, working with the rainfall data of the India Meteorological Department.

A tropical cyclone is driven by the latent heat released when water vapour condenses, so it needs a large warm ocean surface of at least about 27 degrees to supply enough moisture, along with sufficient Coriolis force, which is why cyclones do not form within about five degrees of the…

The Sendai Framework for Disaster Risk Reduction 2015 to 2030 was adopted at the Third United Nations World Conference held at Sendai in Japan in 2015, and it took the place of the Hyogo Framework for Action of 2005 to 2015, which had itself been adopted in Japan at Kobe…

After the Indian Ocean tsunami of 26 December 2004 the country set up a tsunami early warning centre at the Indian National Centre for Ocean Information Services, which works at Hyderabad under the Ministry of Earth Sciences and uses a network of seismic stations, bottom pressure recorders and tide gauges…

The Disaster Management Act, 2005 makes the Chief Minister the ex officio Chairperson of the State Disaster Management Authority, just as the Prime Minister heads the national Authority; in a Union Territory the Lieutenant Governor or the Administrator takes that place.

Under the Disaster Management Act, 2005 the Prime Minister is the Chairperson of the NDMA, which may have other members not exceeding nine, one of them designated Vice-Chairperson; the parallel offices are held by the Chief Minister in a State Authority and the District Magistrate in a District Authority.

The Disaster Management Act, 2005 set up the National Disaster Management Authority, the State Disaster Management Authorities and the District Disaster Management Authorities, and provided for the National Disaster Response Force and the National Institute of Disaster Management.

The earlier Zone I was merged with Zone II, so the map now runs from Zone II, of low hazard, to Zone V, of the highest hazard, which covers Kutch, the Andaman and Nicobar Islands, most of the North-East, parts of northern Bihar and parts of the western Himalaya.

S waves are transverse: the particles move at right angles to the direction of travel, and that requires a medium with shear strength, which liquids do not have.

It expresses magnitude, the energy released at the focus, on a logarithmic scale, so a rise of one whole number means about thirty-two times more energy, and a single earthquake has only one magnitude whatever the distance of the observer.

The energy of an earthquake is released at a point inside the earth, and the point on the surface directly above it is the epicentre, where the tremor is felt first and usually most strongly; it is the point reported in news bulletins.

In this cell hydrogen is fed to the anode and oxidised, oxygen is fed to the cathode and reduced, and the two combine to give water, so the cell produces electricity for as long as the gases are supplied and leaves no polluting exhaust.

Galvanisation is the coating of iron or steel with zinc, usually by dipping the article in molten zinc, and it protects the iron twice over: the layer keeps out air and moisture, and because zinc is the more reactive metal it corrodes in place of the iron even where the…

Pure alumina melts at a very high temperature, so it is dissolved in molten cryolite, which is sodium aluminium fluoride, usually with a little fluorspar added; this brings the working temperature down sharply and makes the melt a good conductor.

The lead-acid cell has a spongy lead negative plate and a lead dioxide positive plate dipped in dilute sulphuric acid, and as the cell discharges both plates turn to lead sulphate while the acid becomes weaker, which is why its state of charge can be judged from the specific gravity…

In the Leclanche dry cell the outer container itself is made of zinc and acts as the anode, being oxidised to zinc ions as the cell works, which is why an old cell often leaks when the container is eaten through.

Its reaction is reversible, so passing a current through it in the opposite direction converts the products back into lead and lead dioxide and the cell can be used again; such a cell is called a secondary or storage cell, and the car battery is the common example.

In the chlor-alkali process a concentrated solution of sodium chloride is electrolysed; chloride ions are oxidised at the anode and come off as chlorine gas, hydrogen is set free at the cathode, and sodium hydroxide remains in the solution, which is why the industry yields three useful products at once.
