Question

Quizplus · Accepted Answer

An antecedent stream is one that maintains its course by downcutting at the same rate as tectonic uplift, thereby keeping pace with changes in the landscape. This allows it to maintain its original path as the surrounding topography is uplifted or eroded. Meandering streams have a sinuous path and do not necessarily maintain their course, while anabranching rivers have multiple channels and rejuvenated rivers have resumed downcutting after a period of relative stability.
