Answer to Question 1

Answer: A delta forms where a stream enters a body of standing water and loses its ability to transport sediment. Large, coarse-grained sediments are the first to settle. Small, fine-grained sediments (able to be carried out to the farther reaches of the delta) are the last to settle. Thus sediment is deposited in order of decreasing weight, with heavy, coarse particles settling at and near the shoreline and light, fine particles settling farther offshore.
