Question

why Western Himalaya is wider than eastern Himalya?

Answer 1

Western Himalaya 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 plainsAmount 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 HimalayasSnowline is Lower than Eastern HimalayasWestern Himalayas receive more precipitation from northwest in the wintersLess biodiversity in comparison to eastern HimalayasThis 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 HimalayasEastern 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
