SSC Selection Post 2022 PYQ — Question 49

The correct answer is option 4 i.e. Thar.

The place in India with the widest difference between day and night temperatures is the Thar Desert, particularly areas like Jaisalmer in Rajasthan.
This desert region experiences extreme temperature variations because the sandy terrain heats up very quickly during the day—reaching temperatures as high as 50°C—and cools down rapidly at night, sometimes dropping to around 15°C. The lack of nearby water bodies means there is no moderating effect on temperature, leading to this significant diurnal temperature range.
