[#136] Doldrums are ________
Correct Answer

(B) Equatorial zone with low pressure

Explanation

Solution: Doldrums are Equatorial zone with low pressure. As this region lies along the equator, it receives highest amount of insolation. Due to intense heating, air gets warmed up and rises over the equatorial region (convection). Whenever there is vertically upward movement of air, the region at the surface will be at low pressure. Thus the belt along the equator is called equatorial low pressure belt.

[#138] In the northern hemisphere, the wind blowing from the Horse latitudes to the Doldrums is called ________
Correct Answer

(B) Trade wind

Explanation

Solution: In the northern hemisphere, the wind blowing from the Horse latitudes to the Doldrums is called Trade wind. Trade wind blow out from the Subtropical High Pressure belts. In the northern hemisphere, they blow towards the equatorial low and called North East Trade Winds. In the Southern hemisphere they blow towards the equatorial low and become the South East Trade winds.

[#139] The dense mass of small water drops on smoke particles in the lower layers of the atmosphere is ________
Correct Answer

(A) Smog

Explanation

Solution: The dense mass of small water drops on smoke particles in the lower layers of the atmosphere is Smog. Smog is a kind of air pollution, originally named for the mixture of smoke and fog in the air. Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulfur dioxide.
