For More Understanding

Explanation

Option (A) is correct because the textbook explicitly states that 'Maximum insolation is received over the subtropical deserts, where the cloudiness is the least. Equator receives comparatively less insolation than the tropics.' This clearly explains that subtropical areas experience higher temperatures because they have less cloud cover, allowing more insolation to reach the surface. The equatorial region, despite receiving direct sunlight, has more cloud cover which reduces the amount of insolation reaching the surface.

Solution Steps

  1. Step 1: Identify the key information from the context about insolation distribution.

  2. Step 2: The context states 'Maximum insolation is received over the subtropical deserts, where the cloudiness is the least.'

  3. Step 3: The context further clarifies that 'Equator receives comparatively less insolation than the tropics.'

  4. Step 4: Match this explanation with the given options - Option (A) correctly identifies less cloud cover in subtropical areas as the reason.
