Question

Quizplus · Accepted Answer

The primary source of Earth's natural heat is radioactive decay in the Earth's core. This process generates heat through the decay of radioactive isotopes, such as uranium and thorium, and it is estimated to produce about 50% of the Earth's internal heat. Molten-hot lava and pressure on the Earth's interior are partly the result of this heat, but they are not the primary source. Solar energy in the form of fossil fuels is an external source of energy, and it has no significant impact on the Earth's internal heat.
