Geysir
Geysir (), sometimes known as The Great Geysir, is a geyser in southwestern Iceland. It was the first geyser described in a printed source and the first known to modern Europeans. The English word ''geyser'' (a periodically spouting hot spring) derives from Geysir. The name ''Geysir'' itself is derived from the Icelandic verb '' geysa'' ("to gush"). Geysir lies in the Haukadalur valley on the slopes of Laugarfjall hill, which is also the home to Strokkur geyser about south. Eruptions at Geysir can hurl boiling water up to in the air. However, eruptions may be infrequent, and have in the past stopped altogether for many years at a time. History The research of sinter shows that Geysir has been active for approximately 10,000 years. The oldest accounts of hot springs at Haukadalur date back to 1294, when earthquakes in the area caused significant changes in local neighbouring landscape creating several new hot springs. Changes in the activity of Geysir and the surrounding g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strokkur
Strokkur ( Icelandic , "churn") is a fountain-type geyser located in a geothermal area beside the Hvítá River in Iceland in the southwest part of the country, east of Reykjavík. It typically erupts every 6–10 minutes. Its usual height is , although it can sometimes erupt up to high. Location Strokkur belongs to the Haukadalur valley area, where various other geothermal feature such as mud pools, fumaroles and other geysers are located around it, such as the famous Geysir geyser, which lies only to the north. History Strokkur was first mentioned in 1789, after an earthquake helped to unblock the conduit of the geyser. Its activity fluctuated throughout the 19th century; in 1815 its height was estimated to have been as much as . It continued to erupt until the turn of the 20th century, when another earthquake blocked the conduit again. In 1963, upon the advice of the Geysir Committee, locals cleaned out the blocked conduit through the bottom of the basin, and the geyser ha ...

Haukadalur
Haukadalur ( Icelandic: , from non, Haukadalr , "hawk dale" or "valley of hawks") is a valley in Iceland. It lies to the north of Laugarvatn lake in the south of Iceland. Geysers Haukadalur is home to some of the best known sights in Iceland: the geysers and other geothermal features which have developed on the Laugarfjall rhyolitic dome. The biggest geysers of Haukadalur are Strokkur and Geysir itself, which gave us the word 'geyser'. ''Strokkur'' is very dependable and erupts every 5 to 10 minutes, whereas the bigger ''Geysir'' nowadays erupts very rarely. There are also more than 40 other smaller hot springs, mud pots and fumaroles nearby. Haukadalur geothermal area was first mentioned in written sources around 1294, when the local hot springs were activated by an earthquake. Earthquakes are also known to have activated local geysers in the recent past, including the earthquakes that occurred on 17 and 21 July 2000. Due to the geysers the valley has been a popular tourist at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geyser
A geyser (, ) is a spring characterized by an intermittent discharge of water ejected turbulently and accompanied by steam. As a fairly rare phenomenon, the formation of geysers is due to particular hydrogeological conditions that exist only in a few places on Earth. Generally all geyser field sites are located near active volcanic areas, and the geyser effect is due to the proximity of magma. Generally, surface water works its way down to an average depth of around where it contacts hot rocks. The resultant boiling of the pressurized water results in the geyser effect of hot water and steam spraying out of the geyser's surface vent (a hydrothermal explosion). A geyser's eruptive activity may change or cease due to ongoing mineral deposition within the geyser plumbing, exchange of functions with nearby hot springs, earthquake influences, and human intervention. Like many other natural phenomena, geysers are not unique to Earth. Jet-like eruptions, often referred to as cryoge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Golden Circle (Iceland)
The Golden Circle ( is, Gullni hringurinn ) is a tourist route in southern Iceland, covering about looping from Reykjavík into the southern uplands of Iceland and back. It is the area that contains most tours and travel-related activities in Iceland. The three primary stops on the route are the Þingvellir National Park, the Gullfoss waterfall, and the geothermal area in Haukadalur, which contains the geysers Geysir and Strokkur. Though Geysir has been mostly dormant for many years, Strokkur continues to erupt every 5–10 minutes. Other stops include the Kerið volcanic crater, the town of Hveragerði, Skálholt cathedral, and the Nesjavellir and Hellisheiðarvirkjun geothermal power plants. The name ''Golden Circle'' is a marketing term for the route, derived from the name of Gullfoss, which means "golden waterfall" in Icelandic.

Robert Bunsen
Robert Wilhelm Eberhard Bunsen (; 30 March 1811 – 16 August 1899) was a German chemist. He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff. The Bunsen–Kirchhoff Award for spectroscopy is named after Bunsen and Kirchhoff. Bunsen also developed several gas-analytical methods, was a pioneer in photochemistry, and did early work in the field of organic arsenic chemistry. With his laboratory assistant Peter Desaga, he developed the Bunsen burner, an improvement on the laboratory burners then in use. Early life and education Bunsen was born in Göttingen, Germany in 1811, in what is now the state of Lower Saxony in Germany. Bunsen was the youngest of four sons of the University of Göttingen's chief librarian and professor of modern philology, Christian Bunsen (1770–1837). After attending school in Holzminden, Bunsen matriculated at Göttingen in 1828 and studied chemistry with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gullfoss
Gullfoss ("Golden Falls"; ) is a waterfall located in the canyon of the Hvítá river in southwest Iceland. History and description The Hvítá river flows southward, and about a kilometre above the falls it turns sharply to the west and flows down into a wide curved three-step "staircase" and then abruptly plunges in two stages (, and ) into a crevice deep. The crevice, about wide and in length, extends perpendicular to the flow of the river. The average amount of water running down the waterfall is per second in the summer and per second in the winter. The highest flood measured was per second. During the first half of the 20th century and some years into the late 20th century, there was much speculation about using Gullfoss to generate electricity. During this period, the waterfall was rented indirectly by its owners, Tómas Tómasson and Halldór Halldórsson, to foreign investors. However, the investors' attempts were unsuccessful, partly due to lack of money. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soap
Soap is a salt of a fatty acid used in a variety of cleansing and lubricating products. In a domestic setting, soaps are surfactants usually used for washing, bathing, and other types of housekeeping. In industrial settings, soaps are used as thickeners, components of some lubricants, and precursors to catalysts. When used for cleaning, soap solubilizes particles and grime, which can then be separated from the article being cleaned. In hand washing, as a surfactant, when lathered with a little water, soap kills microorganisms by disorganizing their membrane lipid bilayer and denaturing their proteins. It also emulsifies oils, enabling them to be carried away by running water. Soap is created by mixing fats and oils with a base. A similar process is used for making detergent which is also created by combining chemical compounds in a mixer. Humans have used soap for millennia. Evidence exists for the production of soap-like materials in ancient Babylon around 2800 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
