Answer:
D) The energy of the sun is made by gravity.
Step-by-step explanation:
D) The energy of the sun is made by gravity.
The correct answer is D. The energy produced by the sun is a result of nuclear fusion reactions that occur in its core. The sun's immense gravitational force, caused by its massive size and mass, creates the pressure and temperature necessary for nuclear fusion to take place. The gravitational force pulls hydrogen atoms in the sun's core together, causing them to collide and fuse, releasing tremendous amounts of energy in the form of light and heat. This energy is what powers the sun and provides heat and light to our solar system. Therefore, the energy of the sun is a direct result of the gravitational forces acting upon it.
