Geysir, a geyser in Iceland, after which the phenomenon is named. [5] Geysers are the most well known hydrothermal feature. [citation needed] They occur when groundwater in underground cavities becomes superheated under a lid of colder surface water. When the superheated water breaches the surface, it flashes to steam, causing the pressure ...
The pressurized water boils, and this causes the geyser effect of hot water and steam spraying out of the geyser's surface vent. A geyser's eruptive activity may change or cease due to ongoing deposition of minerals within their plumbing, exchange of functions with nearby hot springs, earthquake influences, and human intervention.

Several significant geysers erupt near the Paint Pots, notably Fountain Geyser, which usually has several large eruptions a day; Clepsydra Geyser, which is active most of the time except following an eruption of Fountain; and powerful but erratic Morning Geyser, active in the latter part of 2018 following a dormancy of nearly five years.
Geysir is technically a hot water pool geyser rather than a cone geyser so much heat is lost to the atmosphere explaining why the maximum temperature in its conduit is several meters below the top of the water column rather than at the top like is the case with Old Faithful. [10]
Cold water geysers are created by a buildup of carbon dioxide which causes the geyser to erupt. The main article for this category is cold-water geyser . Pages in category "Cold water geysers"
The world's largest active geyser has erupted three times in the past six weeks at Yellowstone National Park.

Castle geyser eruption, Yellowstone National Park. Geysers are springs which will occasionally erupt and discharge hot water and steam. Geysers may indicate ongoing magmatism, water underground is heated by hot rocks and steam pressure builds up before being released along with a jet of hot water. Almost half of all active geysers are present ...
