Consider the following statements:
1. The altitude of the Western Himalayas is higher than the Eastern Himalayas
2. Snowline in Eastern Himalayas is lower than Western Himalayas
3. Eastern Himalayas are much ahead from western Himalayas in terms of Biodiversity
Which among the above statements is / are correct?

Answer: [D] 1, 2 & 3

Western HimalayasEastern Himalayas
Extends till west of River Kali (around 80°E Longitude).This is considered to be ranging from east of the Singalila ranges in Sikkim (88°E Longitudes) to eastern boundaries of Himalayas.
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 plainsThis part rises abruptly from the plains, thus peaks are not faraway from the plains (Example: Kanchenjunga)
Amount of rainfall here is less and is 1/4th of that of Eastern Himalayas.This region received 4 times more rainfall than western Himalayas. Due to high rainfalls, it is covered with dense forests.
The dominant vegetation in the western Himalayas is Coniferous forests and alpine vegetations. The Natural vegetation reflects the impact of lower rainfall.Snowline is LOWER than Western Himalayas
The altitude of the Western Himalayas is higher than the Eastern HimalayasEastern Himalayas receive more precipitation from south-eastern monsoon in the summers.
Snowline is HIGHER than Eastern HimalayasMuch ahead from western Himalayas in terms of Biodiversity and is one of the Biodiversity hotspots
Western Himalayas receive more precipitation from northwest in the winters
Less biodiversity in comparison to eastern Himalayas
