Q

The source of the Sun’s energy is ______.

A) chemical burning

B) nuclear fission

C) potential energy

D) nuclear fusion

E) heat of contraction.

A

The sun is a giant ball of gasses that is in constant motion, and it produces energy through the process of nuclear fusion. Here, two protons (hydrogen atoms) moving at very high speeds collide with each other, forming a helium atom, and releasing energy in the process. This happens in the core of the sun, and in the process of forming a helium atom, some of the hydrogen is converted into heat energy, which is the source of the sun’s energy.
