how does radioactive decay contribute to the internal temperature of the earth?
Answer
Brief Explanations:
Radioactive isotopes like uranium, thorium, and potassium are present in Earth's interior. When these decay, they release energy in the form of heat. This heat generation is a continuous process that contributes to maintaining the high - temperature state of the Earth's interior, driving geological processes such as mantle convection.
Answer:
Radioactive isotopes in Earth's interior decay and release heat, which contributes to maintaining the high internal temperature and drives geological processes.
