(1) The Himalayan Mountains

(2) The Northern Plains

(3) The Peninsular Plateau

(4) The Indian Desert

The Himalayan Mountains

  1. The Himalayas, geologically young and structurally fold mountains.

  2. The Himalayas represent the loftiest and one of the most rugged mountain barriers of the world.

  3. The Himalaya form an arc, which covers a distance of about 2,400 Km.

  4. Their width varies from 400 Km in Kashmir to 150 Km in Arunachal Pradesh.

  5. There are 3 parallel ranges of the Himalayas:

  1. Great or Inner Himalayas or the Himadri

  2. Himachal or lesser Himalaya

  3. Shiwaliks

Great or Inner Himalayas (Himadri)

  • It is the northernmost and most continuous range of the Himalayas.

  • A number of important glaciers descend from this range, making it a key water source.

  • Contains the loftiest peaks, including Kanchenjunga, Nanda Devi, and Mount Everest (in Nepal).

  • The average height is around 6,000 metres.

  • Composed of granite and is perennially snow-bound.

Himachal or Lesser Himalaya

  • Lies south of the Himadri and forms a rugged mountain system.

  • Altitude ranges between 3,700 to 4,500 metres with an average width of about 50 km.

  • Formed of highly compressed and altered rocks.

  • Home to famous valleys like Kashmir, Kangra, and Kullu.

  • Includes notable ranges like Pir Panjal, Dhauladhar, and Mahabharat; region known for hill stations.

Shiwaliks (Outer Himalayas)

  • Southernmost range, formed from unconsolidated sediments deposited by rivers from the main Himalayas.

  • Altitude varies between 900 to 1100 metres with a width of 10–50 km.

  • Known for gravel and alluvium deposits.

  • Features longitudinal valleys between Shiwaliks and Lesser Himalayas, called Duns (e.g., Dehra Dun, Kotli Dun, Patli Dun).

  • Geologically youngest and most fragile part of the Himalayas.
