Fjord
.jpg?width=300)
Geologically, a fjord or fiord (English pronunciation: /ˈfjɔrd/ or /fiˈɔrd/) is a long, narrow inlet with steep sides or cliffs, created by glacial erosion. There are many fjords on the coasts of Alaska, British Columbia, Chile, Greenland, Iceland, the Kerguelen Islands, New Zealand, Norway, Labrador, Nunavut, Newfoundland, and Washington.
