Hur mycket fjordar finns
Near the very coast, the typical West Norwegian glacier spread out presumably through sounds and low valleys and lost their concentration and reduced the glaciers' power to erode leaving bedrock thresholds.

Den sträcker sig över kilometer in i landet, och är som djupast 1 meter. Scoresby Sund på Grönland ( km) Sognefjorden i Norge ( km) Hardangerfjorden i Norge ( km). Drammensfjorden is cut almost in two by the Svelvik "ridge", a sandy moraine that was below sea level when it was covered by ice, but after the post-glacial rebound reaches 60 m ft above the fjord.
Gregory's views were rejected by subsequent research and publications.
Norges mest berömda fjordar hittar du längs västkusten och i landets norra delar. I väst ligger Geirangerfjorden, Hjørundfjorden och Nordfjorden – tre av Unescos världsarv – . De allra mest kända, som Sognefjorden, Lysefjorden, och de UNESCO-listade Nærøyfjorden och Geirangerfjorden, ligger i det västliga Fjord Norge. Längd: kilometer. A hanging valley is a tributary valley that is higher than the main valley and was created by tributary glacier flows into a glacier of larger volume.
In the case of Hardangerfjord the fractures of the Caledonian fold has guided the erosion by glaciers, while there is no clear relation between the direction of Sognefjord and the fold pattern. Hanging valleys are common along glaciated fjords and U-shaped valleys. Sognefjorden är också en av de bredaste fjordarna, med otaliga förgreningar som är mycket smalare än själva huvudfjorden.
Such valleys are fjords when flooded by the ocean. Most fjords are deeper than the adjacent sea ; Sognefjord , Norway , reaches as much as 1, m 4, ft below sea level. Fjordar i Sverige. De längsta fjordarna i världen.

Det finns många fjordar utmed kusterna av Alaska, . Det finns mer än tusen fjordar längs den norska kusten. Confluence of tributary fjords led to excavation of the deepest fjord basins. Karta över alla koordinater från Wikimap eller OSM. Fjords generally have a sill or shoal bedrock at their mouth caused by the previous glacier's reduced erosion rate and terminal moraine.
DE NORSKA FJORDARNA
These characteristics distinguish fjords from rias e. Fjord definieras inom geologi och geografi som en lång, smal havsvik med branta klippsidor som skapats av glacialerosion. This may in particular have been the case in Western Norway where the tertiary uplift of the landmass amplified eroding forces of rivers.
In some cases, this rebound is faster than sea level rise. Thresholds are related to sounds and low land where the ice could spread out and therefore have less erosive force. Thresholds above sea level create freshwater lakes. Men det finns också dramatiska fjordlandskap i Nord-Norge och lite mindre och lugnare fjordar i söder.
Jens Esmark in the 19th century introduced the theory that fjords are or have been created by glaciers and that large parts of Northern Europe had been covered by thick ice in prehistory. Bolstadfjorden is m ft deep with a threshold of only 1. The work of the glacier then left an overdeepened U-shaped valley that ends abruptly at a valley or trough end. A true fjord is formed when a glacier cuts a U-shaped valley by ice segregation and abrasion of the surrounding bedrock.

Sverige har bara ett begränsat antal fjordar som uppfyller den geologiska definitionen för en fjord, det vill säga en vik med en tröskel och en djuphåla. Det finns mer fjordar i Norge, hur ska man kunna välja bland dem?

John Walter Gregory argued that fjords are of tectonic origin and that glaciers had a negligible role in their formation. Saltstraumen in Norway is often described as the world's strongest tidal current.
