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?
(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 StatementII is correct
Answer: (a)
Statement 1 is correct:
The heat capacity of the ocean is much greater than that of the atmosphere or the land. As a result, the ocean slowly warms in the summer, keeping air cool, and it slowly cools in winter, keeping the air warm. The temperature contrast between continents and oceans is greater during summer than in winter
Statement 2 is correct: Specific heat capacity is a measure of how much heat energy is required to raise the temperature of a substance by a certain amount. Water has a relatively high specific heat capacity compared to most other substances, including land surfaces.
