Hint:We will discuss the three ranges one by one.The Himalayas consist of three parallel ranges in its longitudinal extent.These are The Himadri,The Himachal and The Shiwalik.

Complete answer:
(i) The Himadri:
It is known as the Himadri because it remains covered with snow throughout the year.It is also called the Great Himalayas or the Inner Himalayas.It forms the northernmost part of the Himalayan range and is one of the world's highest mountain ranges.This range includes the world's highest peak Mt. Everest and some other peaks,namely, Makalu . Manaslu , Annapurna all in Nepal, Nanga Parbat in Kashmir and also the highest peak in India, Kanchenjunga.
(ii) The Himachal:
This range is also known as the Himachal Himalayas or the Middle or Lesser Himalayas. It runs parallel to the Himadri and lies to its south. Doons lie between the Himachal and Shiwalik ranges. They are flat-bottomed longitudinal valleys. DehraDun is one such valley. Most of the hill stations in India lie in this range. They include Shimla, Mussoorie, Nainital, Almora, Ranikhet, Chakrata, Chail, etc.The valleys here include Kullu, Jammu and Srinagar.
(iii) The Shiwalik Range
It is also called the Outer Himalayas. It is not a continuous range. The slopes facing the subcontinent are steep, while those facing north are gentle. It is known by different names in different places - Jammu Hills in Jammu and Miri, Abor and Mishmi Hills in Arunachal Pradesh.

Note:A number of glaciers descend from the Himadri such as the Gangotri and the Yamunotri. They lie in Uttarakhand. These glaciers are the perennial source of water for the Ganga and Yamuna rivers, respectively.Sharda, Ghagra, Kosi and Gandak rivers originate from this range.
