Question

Quizplus · Accepted Answer

The carbon, oxygen, iron, and silicon in our bodies and surroundings were formed in the interior of stars through nuclear fusion reactions. As stars age, they undergo a series of nuclear fusion reactions that create heavier elements, which are eventually scattered into the interstellar medium by supernova explosions. These elements then become the building blocks for new stars and planets. Therefore, the material in our bodies and surroundings is "recycled" from previous generations of stars.
