[Mission 2024] STATIC QUIZ, 18 August 2023 – Geography

Solution: b)

Statement 2 is incorrect.

Anticyclone is a region where the atmospheric pressure is high compared with that of adjacent areas. In the northern hemisphere the general wind circulation is clockwise round the anticyclone, while in the southern hemisphere it is anticlockwise. The extents are generally large and the effects are also pronounced.

Solution: b)

Doldrums, also called equatorial calms, equatorial regions of light ocean currents and winds within the intertropical convergence zone (ITCZ), a belt of converging winds and rising air encircling Earth near the Equator. The northeast and southeast trade winds meet there; this meeting causes air uplift and often produces clusters of convective thunderstorms. They occur along the Equator in the Indian and western Pacific oceans and slightly north of the Equator off the African and Central American west coasts.

Solution: b)

Statement 3 is incorrect.

Dew point, the temperature at which the atmosphere is saturated with water vapour, when it is cooled without changing its pressure or vapour content. A given volume of air containing much water vapour has a higher dew point than the same volume of drier air; thus the dew point gives an indication of the humidity. In meteorology the dew point is applied, for example, in predicting the height of the base of certain types of clouds. A higher dew point means there will be more moisture in the air.

Solution: a)

The Coramandal Coast stands between the Eastern Ghats and the Bay of Bengal. The Western Ghats runs along the Arabian sea and the lands between these are known as Konkan up to Goa and beyond that as Kanara. The southernmost part is known as Malabar Coast.

The Anaimudi is the highest peak in the southern peninsula.

Palghat Pass is located between the Nilgiri Hills to the north and Anaimalai Hills to the south.

Solution: d)

Some initial conditions for the emergence of a tropical cyclone are:

(i) Large and continuous supply of warm and moist air that can release enormous latent heat.

(ii) Strong Coriolis force that can prevent filling of low pressure at the centre (absence of Coriolis force near the equator prohibits the formation of tropical cyclone between 0°-5° latitude).

(iii) Unstable condition through the troposphere that creates local disturbances around which a cyclone develops.

(iv) Finally, absence of strong vertical wind wedge, which disturbs the vertical transport of latent heat.
