A Stream Crossing a Delta Splits into a Network of Distributaries

question 1

Multiple Choice

A stream crossing a delta splits into a network of distributaries because:

• A) an increase in stream velocity and discharge causes the stream to cut a new stream channel away from the delta.
• B) as waves and shoreline currents erode the delta, the stream seeks new areas in which to deposit its load.
• C) as the delta grows, the decreased stream gradient causes greater sedimentation and clogging of the delta channels.
• D) the stream eventually encounters erosion- resistant rocks that steer it away from the delta.
