Fjord

Long, narrow inlet with steep sides or cliffs, created by glacial activity

In physical geography, a fjord ( FYORD, fee-ORD; also spelled fiord, a variant most common in New Zealand English) is a long, relatively narrow sea inlet with steep sides or cliffs in a valley created by a former glacier, which has since become inundated with water. They are the glacial equivalent of drowned river valleys, known as rias. Fjords exist on the coasts of Antarctica, the Arctic, and surrounding landmasses of the northern and southern hemispheres.
