Deildartunguhver
Deildartunguhver () is a hot spring in Reykholtsdalur, Iceland. It is characterized by a very high flow rate for a hot spring (180 liters/second) and water emerges at 97 °C. It is the highest-flow hot spring in Europe. Some of the water is used for heating, being piped 34 kilometers to Borgarnes and 64 kilometers to Akranes. A fern A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers.

Reykholt, Western Iceland
Reykholt () is a village in the valley of the river Reykjadalsá, called Reykholtsdalur. It is part of Borgarfjörður, Western Region. Reykholt was at one time one of the intellectual centers of the island and had for many years one of the most important schools of the country. The poet and politician Snorri Sturluson lived in Reykholt during the Middle Ages. Sturluson's records of the Old Norse language and mythology of medieval Iceland are invaluable to modern scholars. Remains of his farm and a bathroom with hot pot and a tunnel between the bath and the house can still be visited. The Snorrastofa Cultural / Research Centre was established in Reykholt on September 6, 1988, with opening ceremonies attended by Vigdís Finnbogadóttir, President of Iceland and King Olaf V of Norway.

Hot Spring
A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma (molten rock) or by circulation through faults to hot rock deep in the Earth's crust. In either case, the ultimate source of the heat is radioactive decay of naturally occurring radioactive elements in the Earth's mantle, the layer beneath the crust. Hot spring water often contains large amounts of dissolved minerals. The chemistry of hot springs ranges from acid sulfate springs with a pH as low as 0.8, to alkaline chloride springs saturated with silica, to bicarbonate springs saturated with carbon dioxide and carbonate minerals. Some springs also contain abundant dissolved iron. The minerals brought to the surface in hot springs often feed communities of extremophiles, microorganisms adapted to extreme conditions, and it is possible that life on Earth had ...

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate ( Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ...

Akranes
Akranes () is a port town and municipality on the west coast of Iceland, around north of the capital Reykjavík. The area where Akranes is located was settled in the 9th century; however, it did not receive a municipal charter until 1942. History Akranes was settled in the 9th century by the brothers Þormóður and Ketill, sons of Bresi, who came from Ireland. The town started to form in the mid-17th century as a fishing village. In 1942, it was formally chartered, and in the following years it had the biggest surge in population in its history. Industry has been a big and growing employer: a cement plant has been operated in the town since the 1950s, and an aluminum smelting plant has been in operation near the town since 1998. Economy The fishing industry remains the town's most important source of employment. Akranes also acts as a service center for the large rural region surrounding it. The town is expected to grow in the coming years because of an increase in industri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borgarnes
Borgarnes () is a town located on a peninsula at the shore of Borgarfjörður in Iceland and is the largest town in the Borgarbyggð municipality with a population of about 3800 residents.

Silver Springs, Florida
Silver Springs is an unincorporated community and census-designated place (CDP) in Marion County, Florida, United States. It is the site of Silver Springs, a group of artesian springs and a historic tourist attraction that is now part of Silver Springs State Park. The community is part of the Ocala metropolitan area. It was first listed as a CDP for the 2020 census, at which time it had a population of 2,844. One of Florida's first tourist attractions, the springs drew visitors even before the U.S. Civil War.

Spring (hydrosphere)
A spring is a point of exit at which groundwater from an aquifer flows out on top of Earth's crust ( pedosphere) and becomes surface water. It is a component of the hydrosphere. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and hydrostatic pressure. Their yield varies widely from a volumetric flow rate of nearly zero to more than for the biggest springs. Formation Springs are formed when groundwater flows onto the surface. This typically happens when the groundwater table reaches above the surface level. Springs may also be formed as a result of karst topography, aquifers, or volcanic activity. Springs also have been observed on the ocean floor, spewing hot water directly into the ocean. Springs formed as a result of karst topography create karst springs, in which ground water travels throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australia
Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. With an area of , Australia is the largest country by area in Oceania and the world's sixth-largest country. Australia is the oldest, flattest, and driest inhabited continent, with the least fertile soils. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, with deserts in the centre, tropical rainforests in the north-east, and mountain ranges in the south-east. The ancestors of Aboriginal Australians began arriving from south east Asia approximately 65,000 years ago, during the last ice age.religious_traditions_in_the_world._Australia's_history_of_Australia.html" "title="The_Dreaming.html" ;"title="Aboriginal_Art.html" "title="he Story of Australia's People, Volume 1: The Rise and Fall of Ancient Australia, Penguin Books Australia Ltd., Vic. ...
