– Statement 2: Rivers of the Peninsular Plateau are generally older than Himalayan rivers. They flow through relatively stable and peneplained surfaces. Their valleys are wide and shallow, and the longitudinal profile has gentle gradients, indicating they have reached a mature or old stage of erosion. Thus, statement 2 is correct.
– Statement 3: Himalayan rivers originate from steep mountains (youthful stage with features like V-shaped valleys, rapids, waterfalls), flow through the plains (mature stage with features like floodplains, meanders, oxbow lakes), and finally form deltas before joining the sea (old stage with features like deltas and distributaries). They exhibit characteristics of all three stages of the normal cycle of erosion as described by William Morris Davis. Thus, statement 3 is correct.
