Respuesta :
I need context for this question. I would suggest that you check where the river comes from and see how that affects the river the further it moves away from its source. This seems to be what the question is asking.
Answer:
Near its source, a river is fast moving and flows on a steep mountain slope. It rapidly erodes a V-shaped, steep-sided valley. Its course may include waterfalls and rapids. Farther along its course, a river flows over gently sloping land. Here it flows more slowly, spreading out and eroding the land to form a wide, flat valley. As the river begins to wind from side to side, meanders form.
