Answer: Option B
Solution
Answer: Option B
Solution:
Deltas are formed where the shores are free of hard rocks. When a river reaches a lake or the sea the water slows down and loses the power to carry sediment . The sediment is dropped at the mouth of the river. Some rivers drop so much sediment that waves and tides can't carry it all away. It builds up in layers forming a delta.
