which is the final event that occurs when a star is forming?\no the outer layer of the star expands.\no gravity pulls gas and dust together.\no a black hole forms as the core collapses.\no nuclear fusion begins under high pressure.
Answer
Brief Explanations:
The process of star - formation starts with gravity pulling gas and dust together. As the mass accumulates and the pressure and temperature in the core increase, nuclear fusion begins. This is the final and defining stage of star - formation. A black hole forms in the end - stages of a very massive star's life, not during star - formation. The outer layer expansion is not the final stage of star - formation.
Answer:
Nuclear fusion begins under high pressure.
