The East Coast is a low-relief, passive margin coast.It has been shaped by
the Pleistocene glaciation as far south as New York, with offshore islands Nantucket,
Block Island, Fishers Island, Long Island and Staten Island the result of terminal
moraines.Longshore drift currents have formed an intermittent series of barrier
beaches that enclose sounds that stretch from Long Island Sound southward along
the unglaciated coast.The coastal plain broadens southwards, separated from the
Piedmont districts by the Atlantic Seaboard fall line of the East Coast rivers,
often marking the head of navigation, prominent sites of cities.The seaboard is
susceptible to hurricanes in the Atlantic hurricane season, officially running
from June 1 to November 30, although hurricanes can occur before or after these
dates.Listen song here:YouTube
