[MISSION 2023] RTM(Revision through MCQs)- 1 Apr 2023

Ans: (c )

Explanation:

• Near the equator the ocean water is about 8 cm higher in level than in the middle latitudes. This causes a very slight gradient and water tends to flow down the slope.
• Solar energy makes current warm or cold and decides their circulatory patterns.

Ans: (d)

Explanation:

• Surface currents are generated largely by wind. Their patterns are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents.
• Currents may also be generated by density differences in water masses caused by temperature and salinity variations. These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.
• Occasional events also trigger serious currents. Huge storms move water masses. Underwater earthquakes may trigger devastating tsunamis.

Ans: (c)

Explanation:

• Salinity changes with depth, but the way it changes depends upon the location of the sea. Salinity at the surface increases by the loss of water to ice or evaporation, or decreased by the input of fresh waters, such as from the rivers. Salinity at depth is very much fixed, because there is no way that water is ‘lost’, or the salt is ‘added.’ There is a marked difference in the salinity between the surface zones and the deep zones of the oceans. The lower salinity water rests above the higher salinity dense water. Salinity, generally, increases with depth and there is a distinct zone called the halocline, where salinity increases sharply.

Ans: (c )

Explanation:

• The President can send back the advice given by the Council of Ministers and ask the Council to reconsider the decision. In doing this, the President acts on his (or her) own discretion. When the President thinks that the advice has certain flaws or legal lacunae, or that it is not in the best interests of the country, the President can ask the Council to reconsider the decision. Although the Council can still send back the same advice and the President would then be bound by that advice, such a request by the President to reconsider the decision would naturally carry a lot of weight. So, this is one way in which the president can act at his own discretion.
• Whenever the office becomes vacant, the new president is chosen by an electoral college consisting of the elected members of both houses of parliament (M.P.s), the elected members of the State Legislative Assemblies (Vidhan Sabha) of all States and the elected members of the legislative assemblies (MLAs) of union territories with legislatures, i.eNational Capital Territory (NCT) of Delhi and Puducherry.

Ans: (a)

Explanation:

• Context: The first-ever International Day of Zero Waste was celebrated on March 30, 2023, to encourage people to prevent and minimize waste and promote a circular economy and help achieve the Sustainable Development Goals (11 and 12).
• Established by: The United Nations Environment Programme (UNEP) and UN Human Settlements Programme (UN-Habitat)
• Objective: To raise awareness about zero-waste initiatives and their importance in tackling the global waste crisis.
• The USA generates more waste than any other nation in the world with 4.5 pounds (2 kg) of municipal solid waste (MSW) per person per day. In comparison, the average per capita waste in India is about 670 grams per day.
