Define "base level." What processes cause base level to change?

What will be an ideal response?


The point at which a stream is no longer eroding or depositing sediment. Streams seek to erode to this point. Ultimate base level is sea level. Base level can change when the system changes. Sea level can impact baseline such that when sea level falls, base level falls and the stream must adjust to the new lower shoreline through incision. During sea- level rise, the stream adjusts to a higher shoreline position with deposition occurring in the lower part of the stream.
