Quizplus · Accepted Answer

A parallel drainage network is a type of pattern that forms on very steep slopes that indicate the presence of parallel fractures or faults in the underlying rock. This suggests recent uplift, such as along a fault, which has created steep topography and the subsequent development of this type of drainage network. The other choices are not consistent with the formation of a parallel drainage network.
