The Icelandic word geysir He came to English as geyser, which in our language derived in geyser . This is called a hot spring from which, periodically, steam and hot water emanate.
It is estimated that there are approximately one thousand geysers worldwide. For these structures to emerge certain specific hydrogeological conditions must occur. The geyser activity occurs from the contact of the Water with rocks that are heated by the magma Underground.
The geyser is an opening in the surface that is connected via natural conduits with underground water reserves . While the geyser fills, the surface water gradually cools, but not the water in the reserve. In this way, hot water exerts Pressure over surface water, heating it too. When the boiling point of the water is reached at the bottom of the geyser, the steam rises, causing the water to overflow. The pressure, meanwhile, causes a violent eruption.
Once the geyser entered eruption , the water that remains in the geyser is cooling. The hot water expelled, meanwhile, seeps through the pores and fractures of the rock and the cycle begins again.
The first geyser that was known is called Geysir and it is in Iceland . The term geyser, in fact, is linked to this hot spring, in turn named with an Icelandic word that refers to an eruption. Geysir can eject water about 80 meters from height .
The place with the highest concentration of geysers is the Yellowstone National Park , in U.S . Geyser Old faithful It is the most famous of the region , erupting about five minutes per hour.
