Answer:
nuclear fusion
Explanation:
atoms of hydrogen are ripped apart and fuse to form helium which release energy
Answer:
Energy is produced in a star's center, or core, where pressures are enormous and temperatures reach 27 million°F (15 million°C). This causes nuclear fusion—atoms of hydrogen are ripped apart and fuse (join) to form helium. These reactions release vast amounts of energy, which makes the star shine.
