Atoms that are heavier than iron are generally produced by
A) fission reactions within stars.
B) fusion reactions within stars.
C) explosions of supernovas.
D) the Big Bang.

Question

Quizplus · Accepted Answer

Atoms that are heavier than iron are generally produced through the explosive fusion that occurs during supernova explosions. During these explosions, the pressure and temperature in the star's core become so high that heavier elements can be formed through fusion. Iron is the heaviest element that is formed through fusion in a star's core, after which the star undergoes a process of collapse and explosion, creating heavier elements. Therefore, option C, i.e., explosions of supernovas is the correct choice.
