Geysers were named after a famous "the Great Geysir" of Iceland. That is located around the northwest area of Mt. Hekla, which is also an active volcano in the south central part of the island. That means "roarer" in Icelandic language.
It is a type of hot spring that errupts periodically, ejecting a column of hot water & stream into the air. the name geyser comes from geysir, the name of an errupting spring at Iceland. the word comes from Iceland means "to gush". the formation of geysers require a favourable hydrogeology which exists in only a few places on earth, so they are fairely ran phenomena. about 1000 exist worldwide, half of them is in Yellowstone National Park, US. geyser erruptive may change / cease due to ongoing mineral deposition with in the geyser as plumbing, exchange of functions with near by hot springs, earthquakes influence. geyser activity all hot spring activity is caused by surface water gradually seeping down through the ground until it meets rock heated by magma. geyser differ from non-eeruptive hot springs in their subterranean structure.
The geysers are made by a forceful eruption of water to go to heights of 100 to 200 feet, and the record holding is around 1500 feet. When the water comes to blow off steam, which is responsible for all that roaring. The vigor of these eruptions is what we want to understand more of. Geysers are always around places like hot springs, but then they are a rather unusual phenomenon.
[top]TWO TYPES OF GEYSERS :
[top]1. FOUNTAIN GEYSER :
errupt from pools of water, typically in a series of intense, even violent, burts.
[top]2. CONE GEYSER :
these geysers which errupt from cones of siliceous sinter, usually in steady jets that last anywhere from few seconds to several minutes.
most geysers form in places where there is volcanic rhyolite rock which dissolves in hot water & forms mineral deposite called silicons sinter. many geyser have been destroyed by people throwing litter & debris into them. others have ceased to errupt due to the dewatering by geothermal power plants. the specific colours of geysers derices from the fact that despite the apparently harsh condition, life is often found in them in the form of thermophilic prokaryotes. in the 1960s , when the research of biology of geyser first appeared, scientists were generally convinced that no life can survive above around 73 degree c (163 degree F). the upper limit for the survival of eyanobacteria , as the structure of key cellular proteins & DNA would be destroyed.
[top]Other Physical Nature
In the Earth where there is an opening that would contain superheated water that periodically erupts in a shower of water and of steam. They are found around places where there are heated rocks close to the surface. Iceland is located on the Mid Atlantic ridge noted for its basic activities. Old Faithful is known to be the most famous geyser in Yellowstone National Park, Old Faithful is not the largest geyser in Yellowstone, but is known to be the most frequent on its eruptions on time periods. These eruptions do erupt in about 45 to 110 minutes, with an average of 76 minutes less predictable. However most geysers are always irregular, though Old Faithful ejects 14,000 to 32,000 liters of boiling water to heights of aver 30 to 55 m in each eruption. Approximately 700 geysers, Yellowstone has 500 of all the geysers in the world. Once the other geysers in the Norris Geysers the north Geysers Basin did erupt to 12 to 15 m every 60 seconds.
