Question

why are the southern slopes in himalayan region covered with thick vegetation as compared to northen slopes of same hills?

Answer 1

The southern slopes of the entire Himalayan Range get plenty of rainfall brought by the moisture laden winds of the south-west monsoon.During the south-west monsoon season,the winds proceeding towards the north eastern parts of India are blocked and deflected towards the west side by the Himalayas .These winds travel towards west along the southern slopes of the mountain range bringing heavy rain along the entire route and many rivers descend along these slopes bringing plenty water to the plains at the bottom of the mountain range.This is the main reason for the thick vegetation found along the slopes.Moreover, on the northern side, hilly region extends for hundred of miles preventing the growth of many vegetations.

Answer 2

Its due to a process called orographic rainfall mainly, but also because of the monsoon season that people have mentioned already. So in a nutshell, here it is.

Water and land heat at different speeds (heat capacity). Water takes longer to heat, as such, in the summer months, the air of land warms up faster (remember warm air rises) as such air from the ocean has to move in to take the place of the rising air over the land. This air bring moisture to the region.

As the moisture laden air from the ocean rises up the south side of the mountains, the air cools causing it to release the water as rain, at a certain elevation this rain will fall as snow.. By the time the air is over the mountains, it is very dry as it has lost most of its moisture as snow and rain, as such it causes something called a rain shadow which is an arid region.

Many deserts and arid regions int he world occur in the rain shadows of mountains, look no further than just tot he east of the Rockies and Peruvian Andes to see this.

Hope this helps.

Answer 3

rain. The simple explanation is that moisture comes from the ocean to the south and gets rained out of the air before crossing the mountains.

Answer 4

The monsoon, comes up from the south, India, and deposits all that's left as it approaches the Himalayas
