Question

Quizplus · Accepted Answer

A superposed stream is one that maintains its original course and pattern as it erodes into underlying horizontal beds of different structure than that in which the system evolved. This means that the stream has maintained its pattern despite changes in the underlying geological structures. A deranged pattern refers to a drainage system that lacks an identifiable pattern due to disturbance by glaciation or other factors. Discordant streams are those that do not follow the geologic structure of the surrounding area. Annular patterns refer to circular drainage patterns around a dome or basin.
