Fjord

Geologically, a fjord is a long, narrow inlet with steep sides or cliffs, created in a valley carved by glacial activity. The word comes to English from Icelandic, but related words are used in several Scandinavian languages, in many cases to refer to any long narrow body of water other than the more specific meaning it has in English. Both the whole coast of Norway, Iceland and the island of Greenland have many fjords.
