A) braided stream.
B) graded stream.
C) longitudinal profile.
D) meandering stream.
E) aggradation.

Question

Quizplus · Accepted Answer

A longitudinal profile is a graph that shows the change in elevation or stream gradient along the length of a river, from its source to its mouth. This graph helps in understanding the river's behavior and characteristics such as its ability to erode or deposit sediments, its flow velocity, and energy. The other options such as braided stream, graded stream, meandering stream, and aggradation are not correct because they do not describe a graph showing changes in stream gradient from source to mouth.
