( Hot spring)
A hot spring is a spring that is produced by the emergence of geothermally heated groundwater from the earth's crust. There are hot springs all over the earth, on every continent and even under the oceans and seas. There is no universally accepted definition of a hot spring. For example, one can find the phrase hot spring defined as The related term "warm spring" is defined as a spring with water temperature less than a hot spring by many sources, although Pentecost et al (2003) suggest that the phrase "warm spring" is not useful and should be avoided.[18] The US NOAA Geophysical Data Center defines a "warm spring" as a spring with water between 20&_160;°C (68&_160;°F) and 50&_160;°C (122&_160;°F). In Japan, the ? symbol is commonly used on maps to denote a hot spring. The water issuing from a hot spring is heated by geothermal heat, i.e., heat from the Earth's interior. In general, the temperature of rocks within the earth increases with depth. The rate of temperature increase with depth is known as the geothermal gradient. If water percolates deeply enough into the crust, it will be heated as it comes into contact with hot rocks. The water from hot springs in non-volcanic areas is heated in this manner.
