Answer 1

through the buildup of deposited silt

Step-by-step explanation:

The formation of the Mississippi River Delta can be traced back to the late Cretaceous Period, approximately 100 million years ago, with the creation of the Mississippi embayment. The embayment began focusing sediment into the Gulf of Mexico, which facilitated the deltaic land-building processes for the future.
