Detailed explanation-1: -(iii) These valleys are covered with thick gravel and alluvium. The longitudinal valley lying between lesser Himalaya and the Shiwaliks are known as Duns, such as Dehra Dun, Kotli Dun and Patli Dun.
Detailed explanation-2: -They are chiefly composed of sandstone and conglomerate rock formations, which are the solidified detritus of the Himalayas to their north; they are poorly consolidated.
Detailed explanation-3: -(i) They exceed 10-50 km in diameter and have a height of between 900 and 1100 meters. (ii) These sections are made up of uncoordinated rivers that run down rivers from the main Himalayas to the north. (iii) These valleys are covered with dense alluvium rocks.
