The stream gradient of most rivers ________.

B) is greater near the mouth than near the source
C) does not change significantly as a river flows downstream
D) is greater for a meandering stream than for any other type

Question

Quizplus · Accepted Answer

The stream gradient is steeper near the source of the river as the water flows downhill from high elevations. As the river flows downstream, it encounters less steep slopes and the gradient decreases. Therefore, most rivers have a greater gradient near the source and a lower gradient near the mouth.
