ANSWER
ANTECEDENT RIVER
ANTECEDENT RIVER
An antecedent river is a river that is younger than the underlying geological structure over which it flows.
In areas with active tectonic activity or where erosion significantly affects the landscape, antecedent rivers are frequently discovered. They are an intriguing geological phenomenon that can shed light on how a region's geology has changed through time. Even if the geography of the underlying rocks changes, antecedent rivers do not alter their route.
