Hot spring
A hot spring is a spring produced by the emergence of geothermally heated groundwater from the top layer of the Earth's ground. Hot springs are in many places, especially in mountains. The water issuing from a hot spring is heated by geothermal energy, i.e., heat from the Earth's mantle.
