Fjord

Geologically, a fjord (/ˈfjɔərd/ or i/ˈfiːɔərd/; also spelt fiord) is a long, narrow inlet with steep sides or cliffs, created in a valley carved by glacial activity. The word comes to English from Norwegian, but related words are used in several Scandinavian languages - in many cases to refer to any long narrow body of water, rather than the more specific meaning it has in English. Both the whole coast of Norway and the island of Greenland have many fjords.
