What exam-based understanding comes from regional differences in rainfall distribution?

Correct answer: Geographical reasons behind rainfall of each region should be found

Direct answer: A. Rainfall is not distributed equally because regions differ in latitude, relief, distance from the sea, direction of monsoon winds and exposure to mountain barriers. A good exam answer should therefore identify the geographical reason behind the rainfall pattern of the particular region being discussed. For example, a coastal windward slope may receive heavy rain, while a leeward or rain-shadow area may remain comparatively dry. A is correct because it encourages location-based reasoning rather than memorising one statement for every place. B is wrong because different regions require different explanations. C is wrong because population may be affected by rainfall but does not by itself explain the physical distribution of rain. D is wrong because maps help compare regions and recognise spatial patterns. Memory cue: distribution questions require “place + physical reason + result.”
