The climatic barrier effect of the Himalayas is clear from which result?
Answer and explanation
Correct answer: Reduction in the impact of cold Central Asian winds
The governing concept is the climatic role of the Himalayas as a high mountain barrier. In winter, the Himalayas obstruct the southward movement of extremely cold continental air masses from Central Asia toward the Indian subcontinent. This reduces their direct influence over the plains and helps India retain a comparatively milder winter climate than would otherwise be expected at similar latitudes. Therefore, option D is correct. The other choices do not describe a climatic barrier: coral formation is a marine biological process, the Eastern Ghats do not join the Himalayas, and the Aravallis are an ancient worn-down range rather than a newly formed fold system. The blocking of cold Central Asian winds is the clearest result named in the options.
