Question

Comparison between eastern and western himalayas

Answer 1

Western HimalayasEastern Himalayas

Extends till west of River Kali (around 80°E Longitude).

Height of the mountains from the plains in this part rises in a number of stages. The high mountain ranges are at a long distance from the plains

Amount of rainfall here is less and is 1/4th of that of Eastern Himalayas.

The dominant vegetation in the western Himalayas is Coniferous forests and alpine vegetations. The Natural vegetation reflects the impact of lower rainfall.

The altitude of the Western Himalayas is higher than the Eastern Himalayas

Snowline is Lower than Eastern Himalayas

Western Himalayas receive more precipitation from northwest in the winters

Less biodiversity in comparison to eastern Himalayas

This is considered to be ranging from east of the Singalila ranges in Sikkim (88°E Longitudes) to eastern boundaries of Himalayas.

This part rises abruptly from the plains, thus peaks are not faraway from the plains (Example: Kanchenjunga)

This region receives 4 times more rainfall than western Himalayas. Due to high rainfalls, it is covered with dense forests.

Snowline is Higher than Western Himalayas

Eastern Himalayas receive more precipitation from south-eastern monsoon in the summers.

Much ahead from western Himalayas in terms of Biodiversity and is one of the Biodiversity hotspots

Answer 2

Western himalayas :                          Eastern himalayas:
1. It extends till river kali.                   1. it extends from east of  singalila ranges 
2. Amount of rainfall is less.                   in sikkim
3. The altitude is higher than             2.Amount of rainfall is higher than Western
eastern himalayas.                                  Himalayas.
4.Snowline is lower.                          3.altitude is lesser 
5.less biodiversity                              4. snowline is higher
                                                            5. biodiversity is much more than western
