Question

Which of the following cities in India will have the lowest annual range of temperature?
A. Kolkata
B. Nagpur
C. Jaipur
D. Patna

Answer 1

Hint:- The city is located nearer to a large water body, which causes the moderating effect and thus lowering the annual range of temperature.
- Annual range of temperature refers to the difference in the highest and the lowest temperature mean monthly temperature of the year.

Complete answer:
A. Kolkata - It is closer to the Bay of Bengal and thus the moderating effect of the Bay of Bengal affects the temperature of this city and as a result it experiences low annual variation. In Kolkata the warmest month of the year May, has an average temperature of 30 degrees while January has the lowest average temperature of 19 degrees.
B. Nagpur - Nagpur does not experience the moderating effect of the sea which is why the average temperature during summer and winter is very high. This is because in summers the temperature is very high (may being the hottest month) and in winters temperature become considerably low (december is the coldest month).
C. Jaipur - Being located very far away from the sea Jaipur experiences extreme summer and winter temperatures. Average minimum temperature settles around 8 degrees and the average maximum temperature is 40 degrees. Thus this shows that the annual range of temperature is very high.
D. Patna - In Patna the average maximum temperature remains around 35 degrees while the minimum stays close to 21 degrees. Thus the annual temperature range is moderate.

Hence the correct answer is option A.

Note:In India, the desert areas of Rajasthan have the highest range of temperature and this includes the districts of Jaisalmer and Jodhpur. Siachen glacier and the region of Kashmir has the lowest range of temperature.The largest annual temperature ranges in the World are around the Siberian cold pole in the east of Russia.
