What the species is and where it came from
A geyser is a spring with intermittent, turbulent, steam-accompanied water discharge. It forms where surface water reaches ~2,000 m depth and contacts hot rocks near active volcanic areas.
How it works, in terms someone would actually use
Surface water sinks ~2,000 m to hot rocks. Pressure builds. Boiling triggers explosive discharge of hot water and steam through a surface vent.
What it gets right
It correctly identifies geysers as nonpermanent, steam-accompanied, intermittently erupting springs—dependent on depth, pressure, heat, and hydraulic architecture.
What it does not
It does not persist. It does not occur outside rare hydrogeological configurations. It does not function without proximal magma and precise plumbing geometry.
What it changed
It redefined how we distinguish Earth’s hydrological systems from extraterrestrial cryogeysers: subsurface water circulation is the defining trait.
Who it is for, and who it is not
It is for field geologists, volcanic hazard assessors, and visitors to Yellowstone, Taupō, or El Tatio. It is not for biologists, conservation planners, or anyone seeking stable natural features.
Is it worth your time
Yes—if you want to see a fragile, transient geological pulse shaped by magma, not biology. No—if you expect permanence, predictability, or life.
