The annual range of temperature in the interior of the continents is high as compared to coastal areas. What is/are the reason/reasons?
- 1.Thermal difference between land and water
- 2.Variation in altitude between continents and oceans
- 3.Presence of strong winds in the interior
- 4.Heavy rains in the interior as compared to coasts
Select the correct answer using the code given below:
- A.1 only
- B.1 and 2 only
- C.2 and 3 only
- D.1, 2, 3 and 4
▶ Answer & Explanation
Correct answer: A. 1 only
Land heats up and cools down much faster than water due to differences in specific heat capacity. Coastal areas benefit from the moderating influence of large water bodies, experiencing smaller temperature fluctuations. Continental interiors, far from oceanic influence, experience greater extremes of temperature between seasons. Altitude differences are more relevant to local temperature variations rather than the broad continental vs. coastal annual range. Strong winds can redistribute heat but are not the primary cause of the fundamental difference in annual temperature range.
