Most of Earth’s internal heat is left over from when our planet formed, about 4.5 billion years ago. Earth and the other planets in the solar system first began to take shape as countless smaller bodies collided and clumped together. The energy of those violent collisions transformed into heat energy. As the early … See more This Earth system model is one way to represent the essential processes that are related to the Earth’s internal heat, including plate tectonics and the rock cycle. Hover over the … See more The use of Earth’s internal heat as a renewable energy source can decrease the burning of fossil fuelsand the impact of humans on the Earth … See more Click the icons and bolded terms on this page to learn more about these process and phenomena (e.g. plate tectonics, evolution, etc.). Alternatively, explore the Understanding … See more Earth's internal heat budget is fundamental to the thermal history of the Earth. The flow of heat from Earth's interior to the surface is estimated at 47±2 terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of Earth.
