question 10 (1 point)
what event likely formed earths moon?

a a giant asteroid collision with earth
b the big bang

Explanation:

• Question 8: When a massive star runs out of fuel, its core collapses under gravity, leading to a powerful explosion called a supernova. A star does not turn into a comet, a planet, or become part of another galaxy simply by running out of fuel.
• Question 9: Stars form from clouds of gas and dust called nebulas. The Sun formed in a nebula about 5 billion years ago. Galaxy - collisions are not the typical place for star - formation, the Hadean Eon is a time period on Earth, and the Sun did not form on Jupiter's surface.
• Question 10: The leading theory for the formation of Earth's moon is the giant - impact hypothesis, where a Mars - sized asteroid collided with Earth and debris from the impact accreted to form the moon. The Big Bang is the origin of the universe, not the moon.

Answer:

Question 8: B. it collapses and explodes as a supernova
Question 9: A. in a nebula
Question 10: A. A giant asteroid collision with Earth
