Fjord latest photos
A fjord or fiord (pronounced /fjɔːd/ or pronounced /fiːɔːd/) is a long, narrow bay with steep sides, created in a glacially carved valley that is filled by rising sea water levels. The seeds of a fjord are laid when a glacier cuts a U-shaped valley through abrasion of the surrounding bedrock by the sediment it carries. Many such valleys were formed during recent ice age when the sea was at a much lower level than it is today. At the end of the ice age, the climate warmed up again and glaciers retreated. Sea level rose due to an influx of water from melting ice sheets and glaciers around the world (it rose over 100 m after the last ice age), inundating the vacated valleys with seawater to form fjords. Fjords are often very deep in their upper and middle reaches, in the case of Norway's Hardangerfjord dropping 800 m (2,624 ft) below sea level, although fjords generally have a sill or rise at their mouth associated with the previous glacier's terminal moraine.-Wikipedia-
