A geyser (; ) is a spring characterized by intermittent discharge of water ejected turbulently and accompanied by a vapour phase ( steam ).

Generally all geyser field sites are located near active volcanic areas, and the geyser effect is due to the proximity of magma.

: The water that is ejected from a geyser must travel underground through deep, pressurized fissures in the Earth's crust.

: In order for the heated water to form a geyser, a plumbing system is required.

Streaks on Triton's surface left by geyser plumes suggest that the troposphere is driven by seasonal winds capable of moving material of over a micrometre in size.

Nickelodeon's former studios in Orlando had a green slime geyser and green slime is still dumped on the host of the annual Kids Choice Awards at the end of the ceremony, and on at least one celebrity during the ceremony.

J. Audubon Woodlore is the park ranger of Brownstone National Park ( a play on Yellowstone National Park ), one of the features of which is a geyser named " Old Fateful " ( a play on Old Faithful ).

Lakeview is also known for the hot water geyser, Old Perpetual, located at Hunter's Hot Springs.

Crystal Geyser, a cold water " geyser "--- actually a carbon-dioxide driven, erupting well --- is located about nine miles southeast of town ( Glennon, J. A.

Old Faithful is a cone geyser located in Wyoming, in Yellowstone National Park in the United States.

The geyser, as well as the nearby Old Faithful Inn, is part of the Old Faithful Historic District.

Old Faithful is not the tallest or largest geyser in the park ; that title belongs to the less predictable Steamboat Geyser.

The West Thumb Geyser Basin, including Potts Basin to the north, is the largest geyser basin on the shores of Yellowstone Lake.

Perhaps the most famous hydrothermal feature at West Thumb is a geyser on the lake shore known as Fishing Cone.

Fishing at the geyser is now prohibited.

Geysir (), sometimes known as The Great Geysir, is a geyser in southwestern Iceland.

Geysir lies in the Haukadalur valley on the slopes of Laugarfjall hill, which is also the home to Strokkur geyser about 50 metres south.

Strokkur ( Icelandic for " churn ") is a fountain geyser in the geothermal area beside the Hvítá River in Iceland in the southwest part of the country, east of Reykjavik.

Strokkur and its surrounding areas regularly attracts tourists to view the geyser, as it is one of very few natural geysers to erupt frequently and reliably.

Steamboat Geyser, in Yellowstone National Park's Norris Geyser Basin, is the world's tallest currently-active geyser.

During starship preparations, the geyser region is cleared, and the frozen bodies are discovered.

Located in the southeast corner of the park, Terminal Geyser is not actually a geyser, but rather a cold stream flowing over a steam vent.

In terrestrial hydrothermal systems the majority of water circulated within the fumarole and geyser systems is meteoric water plus ground water that has percolated down into the thermal system from the surface, but it also commonly contains some portion of metamorphic water, magmatic water, and sedimentary formational brine that is released by the magma.

Old Faithful was named in 1870 during the Washburn-Langford-Doane Expedition and was the first geyser in the park to receive a name.

Three mountain peaks, including Mount Norris, one geyser basin, and one pass in Yellowstone are named after Norris.

The geyser was named by the Hayden Geological Survey of 1871.

The centerpiece of the park is " Miss Tilly ," a shrimp boat impaled upon a mountain named " Mount Mayday " that erupts a geyser of water every half hour, right before the bells of the watch sound on Miss Tilly.

The water expelled by the geyser was black with rocks and mud from the surrounding terrain, so the indigenous Māori people named the geyser Waimangu, meaning ' Black Waters '.

In 1870 the Washburn-Langford-Doane Expedition visited the spring, noting a geyser nearby ( later named Excelsior ).

Dr. A. C. Peale named the geyser in 1872.

Bead Geyser was named after the geyser eggs, loose spherical pieces of geyserite, that used to be found near the geyser.

This geyser, named Beehive's Indicator, sends up a fountain between a few seconds and 30 minutes before Beehive erupts, averaging 15 to 20 minutes prior.

: The heat needed for geyser formation comes from magma that needs to be near the surface of the earth.

Passive solar technologies include direct and indirect solar gain for space heating, solar water heating systems based on the thermosiphon or geyser pump, use of thermal mass and phase-change materials for slowing indoor air temperature swings, solar cookers, the solar chimney for enhancing natural ventilation, and earth sheltering.

The geyser has not erupted since June 2009, possibly in part because of controversial nearby geothermal development by the Town of Lakeview to supply the Warner Creek Correctional Facility with water for heating., Additional development of the site for geothermal power generation purposes may further threaten the hot springs.

A further earthquake in 2000 revived the geyser again and it reaches 122 meters for two days, thus becoming one the highest known geysers in history ( Waimangu Geyser in New Zealand has been erupting up to 460 m high ).

After an eruption the geyser often vents large amounts of steam for up to 48 hours.

In Florence there was a predilection for having many small thin elegant jets of water, even when there was enough water to have a large geyser.

The geyser erupts hot water for about 20 minutes in a vertical column that reaches a height of before changing to a noisy steam phase that issues for 30 to 40 minutes.

* Misspelling for " geyser "

Activated for the first time in 1903, the geyser was shut down in 1957 but reactivated early in the current century as yet another city attraction.

The volcanic activity continues as the surface temperature in the core ranges from 100 to 600 ° C at the depth of, which is demonstrated by pouring water into the ground, resulting in a geyser of steam which is an attraction for tourists.

Reimu or Marisa go underground with the help of one of three yōkai ( Yukari Yakumo, Suika Ibuki, or Aya Syameimaru for Reimu ; Alice Margatroid, Patchouli Knowledge, or Nitori Kawashiro for Marisa ) and stop the source of the geyser before things get far too out of hand.

One theory is that it originated from Geysa ( geyser ), old Norse for gush, as, during times of vigorous fermentation, Gueuze will spew out of the bunghole of its enclosing oak barrel.

The geyser erupts for an average of one hundred minutes a day, with eruptions either lasting 7 – 32 minutes, or 98 – 113 minutes.

The name for Dilemma Geyser came from the fact that the two vents of this geyser are surrounded by distinct run-off channels that couldn't be explained by the tiny eruptions that the geyser had prior to 1989.
