Question

The majority of elements heavier than iron in the universe are primarily produced during which process?

a) Nuclear fission

b) Nuclear fusion in stars

c) Radioactive decay

d) Supernova explosions

Answer 1

Heavier elements than iron in the universe are primarily created during supernova explosions through a process called nucleosynthesis, where the conditions allow for the synthesis and dispersal of these elements.

Step-by-step explanation:

The majority of elements heavier than iron in the universe are primarily produced during the process of supernova explosions. During these catastrophic events, the collapse of a star's core and the subsequent explosion provide the extreme conditions necessary for nucleosynthesis, the creation of new chemical elements.

The energy released by the supernova allows for nuclear reactions that synthesize these heavier elements and also results in the dispersal of these materials into space, contributing to the cosmic abundance of elements heavier than iron.
