geothermal activity
Underground thermal phenomena
Geothermal activity is heat-driven phenomena originating from Earth's interior—volcanoes, hot springs, geysers, and underground steam vents.
The term appears in geology, tourism, and energy contexts: Iceland harnesses geothermal activity for heating and electricity.
Regions with significant geothermal activity often feature dramatic landscapes and attract scientific interest.
