UPSC Prelims 2023 – Question 64

Q 64. Consider the following statements: 

Statement I: The temperature contrast between continents and oceans is greater during summer than in winter. 

Statement-II: The specific heat of water is more than that of the land surface. 

Which one of the following is correct in respect of the above statements? 

(a) Both Statement-I and Statement-II are correct and Statement- II is the correct explanation for Statement- I 

(b) Both Statement-I and Statement-II are correct and Statement- II is not the correct explanation for Statement-I.  

(c) Statement I is correct but Statement II is incorrect  

(d) Statement I is incorrect but Statement II is correct 

Correct Answer: Option (b) 

• The temperature contrast between continents and oceans is greater during summer than in winter. This is because of more heat and stronger sea breeze in the summer than in winter. Hence, statement I is correct. 
• The specific heat capacity of water is much greater than the land because the relative density of water is much lower than that of the land surface. However, this is true throughout the year and not related to any particular season. Hence, statement II is correct but it is not the correct explanation for Statement-I.
