Terrestrial Heat Theory

The Terrestrial Heat Theory suggests that Earth’s interior generates heat mainly from the decay of radioactive elements like uranium, thorium, and potassium within its mantle and core. This heat slowly rises toward the surface, causing phenomena such as volcanic activity, geothermal energy, and tectonic movements. Essentially, Earth is like a giant, slowly cooling system with heat produced deep inside, which influences geological processes and the planet's geological stability over time.
