As the glacier moved, it cut away at the top layers of ice and into the sediment below. Melting waters also carved away into the land, meaning that many fjords are actually deeper than the sea that feeds into it. Where the fjord meets the sea, also known as the mouth, many glaciers left behind shill or shoal rock deposits. Because the mouth is a shallower opening than the body of the fjord, it results in extremely fast-moving water this includes strong currents and saltwater rapids.
Although fjords share a common formation story, they do not all share the same geological features. Some of these varying features include hydrology, epishelf lakes, coral reefs, and skerries. Below is a closer look at each characteristic:. Hydrology refers to the behavior or characteristics of the water within the fjord. In most places, the warmer temperatures of summer result in snow and ice melting into local rivers.
These overflowing, freshwater rivers often flow into the fjord, mixing with the saltwater. This mixture creates brackish water, the surface of which rises above the surface of the open sea. Because of the difference in surface elevations, the top layer of water flows into the sea. At the same time, the bottom layer of saltier water moves into the fjord.
Some of the deepest waters remain very cold and do not move. Scientists love to study fjords as model systems.
Are there sharks in fjords? However, fjords can be found in some areas south of the equator that are near coastal mountain ranges, most notably New Zealand and Chile. Other charismatic species that regularly utilize fjords include killer whales and other whales, Greenland sharks, several species of seals, and several different salmon species.
What is a synonym for Fjord? Synonyms for fjord nounnarrow inlet inlet. Are fjords dangerous? As glaciers formed fjords, they would often leave deposits behind that would create a rise at the mouth of the fjord.
This rise can cause some fjords to have very strong currents or even saltwater rapids. Another dangerous feature found near some fjords is the presence of thousands of small, rocky island blocks. Is Fjord an English word? What country has fjords?
