Explanation:
The Himalayas along with other Peninsular mountains are young, weak and flexible in theirgeological structure unlike the rigid and stable Peninsular Block. Consequently, they are stillsubjected to the interplay of exogenic and endogenic forces, resulting in the development offaults, folds and thrust plains. These mountains are tectonic in origin, dissected by fastflowing rivers which are in their youthful stage. Therefore, various landforms like gorges,Vshaped valleys, rapids, waterfalls, etc. are indicative of this stage. These are both due tothe speed of the rivers as well as the weak geological structure.
