A hot spring is a natural geothermal feature where groundwater is heated by the Earth’s internal heat and rises to the surface, often resulting in the formation of thermal pools. Hot springs are significant in geothermal energy, mineral deposition, and unique ecosystems that thrive in warm, mineral-rich waters.
