Hot Springs

Dictionary.png
Hot Springs:
A naturally occurring spring of hot water, heated by geothermal processes in the subsurface, and typically having a temperature greater than 37°C.
Other definitions:Wikipedia Reegle



Hot springs occur where geothermally heated waters naturally flow out of the surface of the Earth. Hot springs may deposit minerals and spectacular features such as terraces of travertine or silica, tufa mounds, and sulfuric deposits.
