Question

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

Options

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

Answer

Explanation

Statement-I is incorrect; the temperature contrast between continents and oceans is actually starker in winter (especially in the Northern Hemisphere) because landmasses lose heat far more rapidly than oceans, creating extreme cold continental interiors relative to oceans. Statement-II is correct; water possesses a significantly higher specific heat capacity, meaning it heats and cools much slower than land.

The differential heating of land and water—driven by water's high specific heat—is the foundational engine for monsoons and coastal breezes.

Answer: (d).
