How do hot springs get their heat?
GeologyHydrogeology
Quick Answer
Groundwater circulates underground, sinks deep enough to meet hot rock, and rises back to the surface. In volcanic regions this heating can happen quickly; elsewhere it may be warmed by normal geothermal heat.
The Full Story
Hot springs are powered by Earth’s internal heat. Rain or snowmelt seeps underground, travels through cracks and porous rock, and is heated by geothermal energy from below. In volcanic regions, the water may encounter magma-heated rock and emerge very hot; in non-volcanic settings, it may simply be warmed by the normal geothermal gradient. The result is a spring whose temperature can be much higher than local groundwater.
Key Facts
1.Water is heated by Earth’s internal geothermal energy
2.Volcanic regions can produce especially hot springs
3.The geothermal gradient warms rock with depth
