Question

Quizplus · Accepted Answer

Nuclear fusion is not considered a process that contributed to the early Earth remaining molten longer. The primary processes thought to have contributed include the impact of space debris, natural radioactive decay, and potentially nuclear fission within Earth's core, but not nuclear fusion, which occurs in stars, not planets.
