Temperature and precipitation play an important role in determining the climate of a region.
In this regard, consider the following statements regarding temperature variation in southern India:
1. Due to the presence of southern India in the tropical zone, the diurnal range of temperature is high.
2. Due to the continental influence, the annual mean range of temperature is greater in the coastal regions.
Which of the statements given above is/are CORRECT?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Neither 1 nor 2.
Southern India lies in the tropical zone and is surrounded by seas on three sides. The strong maritime influence moderates temperature throughout the year. As a result, the diurnal range of temperature, which means the difference between day and night temperatures, is generally low rather than high. Coastal winds and humidity prevent extreme temperature variations.
The second statement is also incorrect because coastal regions experience less annual temperature variation due to the moderating effect of the ocean. In contrast, interior parts of southern India, which are farther from the sea, experience greater continental influence and therefore show a higher annual mean range of temperature.
Hence, neither Statement 1 nor Statement 2 is correct.
