Answer:
1) Himadri range
It is the most northerly of the Himalayas and is often referred to as the inner or greater Himalayas.
The mountains have an average height of about 6000 meters from ocean level.
In the Himadri range, a lot of glaciers are located and many rivers source are here.
It is the most continuous range and comprises granite as its core.
It includes peaks such as Kanchenjunga, k2, etc.
Himachal range
The range lying to the south of the Himadri forms the most rugged mountain system and is known as Himachal or lesser Himalaya.
In this range, the altitude is about 3700-4500 meters above sea level.
Many popular hill stations such as Shimla, Mussoorie, Kullu valley etc. are located in this range.
This range has an average diameter of about 50kms.
The range of Himachal is very rough and made up of compressed rocks.
The most significant sub-ranges of the Himachal range include pir panjal, Mahabharat and dhauladhar.
Shiwaliks range
The Himalayas’ outermost range is called the Outer Himalayas or Shiwaliks. They stretch over 10-15 km in width.
Their height ranges from 900-1100 meters.
They are discontinuous ranges and consist of unconsolidated sediments, gravel and alluvium from the major
Himalayan ranges situated farther north, carried down by the rivers.
Longitudinal valleys known as Duns lie between the lesser Himalayas and Shiwaliks, e.g., Dehradun, Kotli Dun, Patli Dun.
