(i) The rivers, after coming down from the mountains deposit pebbles in a narrow belt of about 8 to 16 km in width lying parallel to the slopes of the Shiwaliks which is known as Bhabar.

(ii) The three major divisions of the Himalayas from north to south are :

(a) Great or Inner Himalaya: It contains all prominent Himalayan peaks. The folds of the Great Himalayas are asymmetrical and its core is made of granite. It is perennially snowbound, and several glaciers descend from this range that's why it is also called Himadri.

(b) Middle Himalayas: The range lying to the south of the Himadri forms the roughest mountain range which is known as Himachal or lesser Himalaya. Its width is approx. 80 to 100 km. Its average height is 2000 m. to 3500m and its maximum height is 4500 m.

(c) Shiwalik Range or Outer Himalaya: The outermost range of the Himalayas is called the Shiwaliks. This is the newly constructed part of the Himalayas which stretches from the south Potwar Basin of Punjab to the Kosi river in the East. These ranges have an altitude varying between 900 to 1100 m. and extend over a width of 10-50 km.

(iii) Malwa Plateau lies between the Aravali and the Vindhyan ranges.

(iv) Lakshadweep islands of India have a coral origin.
