Which of the following best describes the role of gravity in supernova formation?.
- A.Gravity causes the star to expand rapidly.
- B.Gravity pulls the outer layers inward, leading to collapse.
- C.Gravity has no significant effect on supernova formation.
- D.Gravity only affects smaller stars.
Model answer
What a good answer should say
- Gravity pulls the outer layers inward, leading to collapse.
Explanation
Why this works
In massive stars, gravity plays a critical role by pulling the outer layers inward once nuclear fusion stops, resulting in core collapse and triggering a supernova explosion.
