What is the superimposed stream?

Answer 1

A superimposed stream refers to a river or stream that maintains its course over a landscape even as the underlying geology changes due to processes like erosion or uplift. This occurs when a stream cuts through layers of rock and sediment, forming a valley that remains in place despite changes in elevation or terrain. Such streams often indicate a history of geological events and can reveal insights into the landscape's evolution. The term highlights the stream's ability to persist and flow over different geological structures.
