If a Storm Causes More Sediment (Dirt)to Flow into a River

Multiple Choice

If a storm causes more sediment (dirt) to flow into a river than the river can carry,the sediment will be deposited in the channel.This will make the channel narrower than it was originally.However,as the channel's width decreases,the river's velocity will increase,and this will eventually cause the newly deposited sediment to be eroded.As a result,the original width of the river,as well as normal flow velocities,will be reestablished.In this example,the width of the river channel and the processes controlling it can be considered an example of

A) dynamic equilibrium.
B) positive feedback.
C) negative feedback and steady-state equilibrium.
D) chaos
E) steady-state feedback
