Consider the microclimatic temperature variations across Kerala: Statement I: The high-range tracts of Munnar and Wayanad experience significantly lower diurnal and annual mean temperatures compared to the coastal plains. Statement II: Atmospheric temperature decreases with an increase in altitude in accordance with the normal environmental lapse rate. Which of the following is correct?
A. Both Statement I and Statement II are correct, and Statement II is the correct explanation for Statement I.✓ Correct Answer
B. Both Statement I and Statement II are correct, but Statement II is not the explanation for Statement I.
C. Statement I is correct, but Statement II is incorrect.
D. Statement I is incorrect, but Statement II is correct.
💡 Solution & Explanation
High-altitude tracts in regions like Munnar experience cooler temperatures because atmospheric temperature decreases with altitude according to the normal environmental lapse rate of roughly 6.5 degrees Celsius per kilometer. Coastal plains lack this elevation factor, maintaining higher mean temperatures throughout the year. Thus, Statement II directly explains the climatic phenomenon observed in Statement I.
