Beach zone of loose particles that covers part or all of a shore US has about 11000 miles of beaches 30 of shoreline Beaches form at calm spots between headlands shores sheltered by barrier islands Outer Banks. Erosion by rivers, streams, waves, floods.. Rivers and streams often sort sediments. Large sediments are deposited upstream and small sediments are deposited downstream. .
