4. Comparing to other regions, the day night temperature difference will be maximum in which among the following regions?
[A] Tundra
[B] Mediterranean
[C] Tropical Deserts
[D] Equatorial
Show Answer
Correct Answer: C [Tropical Deserts]
Notes:
Tropical desert regions, such as the Sahara Desert, experience significant day-night temperature differences. During the day, temperatures in these areas can become extremely hot, often exceeding 100 degrees Fahrenheit (38 degrees Celsius), while nighttime temperatures can drop significantly, sometimes plummeting to near-freezing levels, particularly in desert areas with low humidity. This makes the day-night temperature difference in tropical deserts quite substantial.
5. Strait of Hormuz connects:
[A] Sea of Oman to Persian Gulf
[B] Red sea to Gulf of Aden
[C] Red sea to Indian ocean
[D] Mediterranean sea to Red sea
Show Answer

[D] land-forms created by simultaneous erosion and deposition in a stream channel
Show Answer
Correct Answer: A [a type of desert landscape]
Notes:
Hamada is a type of desert landscape consisting of high, largely barren, hard rocky plateaus with very little sand because this has been removed by deflation. Hamadas are produced by the wind removing the fine products of weathering: an aeolian process known as deflation.
8. United States and parts of Northern America are frequently hit by record snowfalls accompanied with blizzard and hurricane-force winds during winters. Which of the following is most probably responsible for the same?

[C] El-Nino
[D] Pacific Decadal Oscillation
Show Answer
Correct Answer: A [Polar Vortex]
Notes:
Polar Vortex is a whirling cold winds present at both North Pole and South Pole.
It results because of the increased temperature difference between the dark, frigid Arctic and the warm tropics. There are two vortices, one in the layer of the upper atmosphere known as the stratosphere and one in the lower section, where our weather happens, called the troposphere. These two features interact with each other and can affect the meteorological goings-on outside of the Arctic.
