Question

What produced the helium now present in the sun's atmosphere?

A) Nuclear fusion
B) Volcanic activity
C) Solar flares
D) Cosmic radiation

Answer 1

The helium in the Sun's atmosphere is produced through the process of nuclear fusion.

Step-by-step explanation:

The helium in the Sun's atmosphere is produced through the process of nuclear fusion. Nuclear fusion is the process in which smaller atomic nuclei combine to form a larger nucleus, releasing a large amount of energy. In the Sun, hydrogen nuclei (protons) fuse together to form helium nuclei. This fusion reaction releases energy and is responsible for the Sun's heat and light.
