The satellite image below shows a ship channel between South Padre Island and Boca Chica beach on South Texas. Sand is sometimes removed from the ship channel through a process called dredging to make it easier for ships to travel through. Recently sand from the bottom of the channel was moved to area beaches. Without this transfer of sand, what would most likely occur in this are in the future?

• The ship channel would become deeper, and the island would move west toward the mainland.

• The ship channel would become shallower, and the beach would become narrower.

• The ship channel would become narrower, and the island would become completely covered with water.

• The ship channel would become wider, and the island would sink into the Gulf of Mexico.
