(1) The Great or Inner Himalayas:
This is the northernmost range and is also known as Himadri. This is the most continuous range. It contains the loftiest peaks. The average height of peaks in this range is 6,000 metres. All the prominent Himalayan peaks are in this range. The folds of the Great Himalayas are asymmetrical in nature and the core of this part is composed of granite. Because of the lofty heights, the peaks of this range are perennially snow-bound.
(2) The Lesser Himalaya or Himachal:
This lies towards the south of the Great Himalayas. The altitude of peaks in this range varies from 3,700 m to 4,500 m. Average width of this range is 50 km. This range is mainly composed of highly compressed and altered rocks.
(3) The Shiwaliks:
This is the outermost range of the Himalayas. The altitude varies between 900 and 1100 km in this range and the width varies between 10 to 50 km. These ranges are composed of unconsolidated sediments. The longitudinal valleys lying between the Himachal and Shiwaliks are called Dun.
