jarðarborðsvarmi
Jarðarborðsvarmi refers to the heat originating from within the Earth. This internal heat is a product of the planet's formation and the continuous radioactive decay of elements within its core and mantle. The temperature increases significantly with depth, a phenomenon known as the geothermal gradient.
This geothermal heat has been harnessed for various purposes, primarily for electricity generation and direct heating
The accessibility and intensity of geothermal resources vary geographically. Volcanically active areas and regions with tectonic
