Question

Two places, X (terrestrial) and Y (marine), are at the same latitude. During summer, Place X records 42C and Place Y records 32C. During winter, Place X records 0C and Place Y records 10C. What is the most plausible explanation?

1. A. Variation in the altitudes of Place X and Y
2. B. Land has a higher specific heat capacity than oceans
3. C. Land has a lower specific heat capacity than oceans (Correct answer)
4. D. Variation in thermal insulation at places X and Y

Correct Answer

Option C — Land has a lower specific heat capacity than oceans

Detailed Solution & Explanation

The correct answer is Land has a lower specific heat capacity than oceans.

Key Points

• Land heats and cools faster than oceans because land has a lower specific heat capacity.
• This explains X higher summer and lower winter temperatures compared to coastal Y.
