Statement I: The Doldrums is a low-pressure area around the Equator where the prevailing winds are calm Statement II: Low pressure is caused by the heat at the Equator which makes the air rise and travel both Northwards and Southwards

The correct answer is 1.

Key Points

  • Equatorial Low-Pressure Belt or ‘Doldrums’-
    • It is located in the vicinity of the geographical equator between 5° North and 5° South latitude.
    • Width may vary between 5°N and 5°S and 20°N and 20°S.
    • This belt is also called the Doldrums, because of the extremely calm air movements. Hence, statement 1 is correct.
    • It is the region of convergence of trade winds blowing equatorward from the sub-tropical belts of high pressure in the northern and southern hemispheres. Hence, statement 2 is correct and Statement 2 is the correct explanation of Statement 1.
    • The position of the belt varies with the apparent movement of the Sun.

Important Points

  • Formation of Equatorial Low-Pressure Belt
    • ​As this region lies along the equator, it receives the highest amount of insolation.
    • Due to intense heating, the air gets warmed up and rises over the equatorial region (convection).
    • Whenever there is a vertically upward movement of air, the region at the surface will be at low pressure. Thus the belt along the equator is called the equatorial low-pressure belt.

The question below consists of a set of labelled sentences. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. P: Intense heating of the ground creates convection currents. Q: Dust storms are caused by strong winds that travel over dry, arid land with little vegetation and pick up tiny particles such as sand, dust and other debris. R: The air over the ground becomes hot and rises and the vacuum it creates is filled by cooler winds, resulting in a storm. S: In arid areas, the storm picks up sand and loose soil, which are light and thus travel fast with it.
