How is the climatic barrier effect of the Himalayas understood?
Answer and explanation
Correct answer: It affects Indian climate by blocking cold Central Asian winds
The governing concept is the climatic role of the Himalayas as a major northern barrier. Their high, continuous ranges obstruct extremely cold continental winds from Central Asia during winter, helping northern India avoid the full severity of that cold air. They also influence the monsoon by preventing moisture-bearing winds from moving freely northward and by encouraging uplift and rainfall along suitable slopes. Therefore, option A correctly describes the barrier effect. Option B concerns the volcanic origin and weathering associated with Deccan basalt, while options C and D describe no accepted geographical process. The effect is not that the Himalayas control every feature of Indian climate, but that their position and elevation are crucial influences.
