Question

graded streams have a smooth, concave - upward profiles because there is no net erosion or deposition causing the stream profile to change. true false

Explanation:

A graded stream is in a state of equilibrium. In this state, the sediment load it carries is in balance with its transporting capacity. This balance means that there is no net erosion (where the stream would deepen or widen its channel by removing sediment) or net deposition (where sediment would accumulate in the channel). As a result, the stream profile remains relatively stable with a smooth, concave - upward shape.

Answer:

True
