The pressure of the water in the plumbing system above keeps the water from expanding.
(Copyright Lee Krystek, 2000 weird Geology: Geysers, geysers are some of the most unusual geologic phenomena in the world.
Slowly it sealed itself closed with geyserite so that pressure build up promo box beauté and in 1985 it started erupting continuously.Though the water is hot and under pressure it would never be ejected from geysers with such tremendous force if it were not for the special quality of the rocks in the geyser fields.Geologically speaking, no geyser exists for very long.The premiere place to see geysers, however, is Yellowstone National Park in the United States.In a "cone" geyser, the geyserite has formed a type of nozzle near the surface.
In a fountain-type geyser there is an open crater that fills with water before or during the eruption.
Secondly, there must be a v olcanic heat source.
Despite its age, Castle still gives spectators a good show by erupting every 10 to 12 hours for almost as long as an hour.
In addition to the "cone" style of geyser, there is a "fountain" type of geyser.
A fumarole is a steam vent.While the water is pure, it is not recommended idée cadeau qui reste for drinking as small amounts of dissolved minerals, such as arsenic and sulfur, may be present.This melts the surrounding rock to turn the water into a muddy clay.While geysers are rare (there are less than 700 known geysers in the world) they are not impossible for the average person to observe.It reaches a boiling point and wants to turn to steam, but it can't.
The size of its cone, in the shape that reminds people of a castle, indicates that it may be somewhere between 5,000 and 40,000 years old.
