Which evidence gives the strongest combined indication of river rejuvenation?
Answer and explanation
Correct answer: Incised meanders, river terraces, and knickpoints
River rejuvenation means renewed erosional energy, usually after uplift, sea-level fall, or increased discharge. The river cuts downward into former meanders, leaves abandoned valley-floor surfaces as terraces, and creates knickpoints along its long profile. Their combined occurrence is therefore strong evidence of renewed incision, making option B correct. The other choices represent coastal, aeolian, or karst features rather than rejuvenation.
