Barrier Island
Barrier Islands, a coastal landform and a type of barrier system, are relatively narrow strips of sand that are parallel to the mainland coast. They usually occur in chains, consisting of anything from a few islands to more than a dozen. Excepting the tidal inlets that separate the islands, a barrier chain may extend uninterrupted for over a hundred kilometers, the longest and widest being Padre Island. The length and width of barriers and overall morphology of barrier coasts are related to parameters including tidal range, wave energy, sediment supply, sea-level trends and basement controls.
Chains of barrier islands can be found along approximately thirteen percent of the world's coastlines, some displaying different settings, suggesting that they can form and be maintained in a variety of environmental settings. Numerous theories have been given to explain their formation.

Famous quotes containing the words barrier and/or island:
“Clearly, some time ago makers and consumers of American junk food passed jointly through some kind of sensibility barrier in the endless quest for new taste sensations. Now they are a little like those desperate junkies who have tried every known drug and are finally reduced to mainlining toilet bowl cleanser in an effort to get still higher.”
—Bill Bryson (b. 1951)
“Your kind doesn’t just kill men. You murder their spirits, you strangle their last breath of hope and freedom, so that you, the chosen few, can rule your slaves in ease and luxury. You’re a sadist just like the others, Heiser, with no resource but violence and no feeling but fear, the kind you’re feeling now. You’re drowning, Heiser, drowning in the ocean of blood around this barren little island you call the New Order.”
—Curtis Siodmak (1902–1988)
