Question

Why are the southern slopes in himalayan region covered with thick vegetation cover as compared to northern slopes of same hills?

Answer 1

The southern slopes of the Himalayas are covered with vegetation in comparison to the northern slopes due to the following facts:

• They receive more sunshine. The maximum ascent of the sun towards the north of equator is up to the Tropic of Cancer which lies below the southern slopes of Himalayas. As such, they receive more light.
• The southern slopes receive more rainfall as they face the rain bearing monsoon winds. The northern slopes, on the other hand receive scanty rainfall as they are in the rain shadow area and thus have less vegetation.
