Geyser | Definition, Formation, Locations, & Facts | Britannica
2024年10月23日 · Geyser, hot spring that intermittently spouts jets of steam and water. The term is derived from the Icelandic word ‘geysir,’ meaning ‘to gush.’. Geysers result from the heating of groundwater by shallow bodies of magma. They are generally associated with areas that have seen past volcanic activity.
Geyser - Wikipedia
A geyser (/ ˈ ɡ aɪ z ər /, UK: / ˈ ɡ iː z ər /) [1] [2] is a spring with an intermittent discharge of water ejected turbulently and accompanied by steam. The formation of geysers is fairly rare, and is caused by particular hydrogeological conditions that exist only in a few places on Earth.
Geysers | Geology, Formation - Geology Science
2023年4月23日 · The formation and operation of geysers involve a complex interplay of geology, hydrogeology, and thermodynamics. Geysers are formed and sustained by a combination of heat, water, and underground conduits that allow for the periodic eruptions of hot water and steam.
Geysers—what exactly are they made of? | U.S. Geological Survey
First, a brief overview on how geysers form. It begins with groundwater flowing through rhyolitic rocks. These rhyolitic rocks mainly consist of silica (SiO 2) and are heated by a deep magma body beneath the Yellowstone Caldera. As hot groundwater flows through the rhyolitic rocks, it dissolves parts of the rock.
How Geysers Work - HowStuffWorks
In this article, we'll explore what else it takes to form a geyser, what exactly causes one to erupt and what makes some geysers so unique. Along the way, we'll also take a look at some springs that look and act like geysers, but operate in a completely different way. Contents. How Geysers Form and Erupt.
geyser - National Geographic Society
2023年10月19日 · A geyser is a rare kind of hot spring that is under pressure and erupts, sending jets of water and steam into the air. Geysers are made from a tube-like hole in the Earth's surface that runs deep into the crust. The tube is filled with water.
What is a Geyser? | Geyser Pictures & Video | Hot Water! - Geology.com
A geyser is a vent in Earth's surface that periodically ejects a column of hot water and steam. Even a small geyser is an amazing phenomenon; however, some geysers have eruptions that blast thousands of gallons of boiling-hot water up to a few hundred feet in the air. Old Faithful is the world's best-known geyser.
How Geysers Erupt - Teachers (U.S. National Park Service)
2023年11月2日 · A geyser is a hot spring that erupts periodically and forcibly ejects water. Three ingredients are necessary for a geyser to exist: a source of heat, an abundant supply of water, and a special underground plumbing system.
How Geysers Work - Yellowstone - U.S. National Park Service
How Geysers Work. For geyser to occur there must be heat, water, and a plumbing system. A magma chamber provides the heat, which radiates into surrounding rock. Water from rain and snow works its way underground through fractures in the rock.

2023年3月16日 · Geysers are hot springs whose eruptions are non-continuous. They are formed when subterranean water percolates and gets in contact with molten magma which heats the water and causes it to spurt out at periodic intervals.
