Key Concepts

Radioactive Decay

Radioactive decay is the process by which unstable isotopes release energy in the form of heat as they transform into more stable forms. This decay is a major contributor to the internal heat of the Earth, ensuring that a significant and steady amount of energy is available to sustain geothermal processes over geological time scales.

Geothermal Energy

Geothermal energy refers to the heat stored beneath the Earth's surface that can be utilized for heating, electricity generation, and other applications. It is based on the natural and renewable heat source found within the Earth, which continuously replenishes due to ongoing geological processes.

Earth's Internal Heat

Earth's internal heat is primarily a result of residual energy from the planet's original formation combined with ongoing heat production processes, most notably the radioactive decay of unstable isotopes within the Earth's mantle and core. This continuous output of heat drives geological phenomena such as mantle convection, volcanic activity, and plate tectonics.
