Question

Quizplus · Accepted Answer

The making of abundant iron nuclei is typical of type II supernovae. This is because during the core collapse of a massive star, temperatures and pressures become so high that the fusion of heavier elements, including iron, can occur. This fusion produces an enormous amount of energy, which drives the explosion of the star.
