A coastline or seashore is the area where land meets the sea or ocean. A precise line that can be called a coastline cannot be determined due to the dynamic nature of tides. The term "coastal zone" can be used instead, which is a spatial zone where interaction of the sea and land processes occurs. Both the terms coast and coastal are often used to describe a geographic location or region; for example, New Zealand's West Coast, or the East and West Coasts of the United States.
A pelagic coast refers to a coast which fronts the open ocean, as opposed to a more sheltered coast in a gulf or bay. A shore, on the other hand, can refer to parts of the land which adjoin any large body of water, including oceans (sea shore) and lakes (lake shore). Similarly, the somewhat related term "bank" refers to the land alongside or sloping down to a river (riverbank) or to a body of water smaller than a lake. "Bank" is also used in some parts of the world to refer to an artificial ridge of earth intended to retain the water of a river or pond. In other places this may be called a levee.
While many scientific experts might agree on a common definition of the term "coast", the delineation of the extents of a coast differ according to jurisdiction, with many scientific and government authorities in various countries differing for economic and social policy reasons.
Famous quotes containing the word coast:
“On the Coast of Coromandel
Where the early pumpkins blow,
In the middle of the woods
Lived the Yonghy-Bonghy-Bo.
Two old chairs, and half a candle,
One old jug without a handle,
These were all his worldly goods:
In the middle of the woods,”
—Edward Lear (18121888)
“Beyond this island bound
By a thin sea of flesh
And a bone coast ...”
—Dylan Thomas (19141953)
“Have we even so much as discovered and settled the shores? Let a man travel on foot along the coast ... and tell me if it looks like a discovered and settled country, and not rather, for the most part, like a desolate island, and No-Mans Land.”
—Henry David Thoreau (18171862)
