Question

question 3
whats the leading theory for the origin of the moon?
it split out of a rapidly rotating earth.
it formed in the same place (i.e. entirely from the same accretion disk) as the earth.
it formed from the material ejected by a giant impact between earth & a mars - sized object.
the earth captured a wandering solar system body 4 billion years ago & thats the moon.

Explanation:

The giant - impact hypothesis is the leading theory for the Moon's origin. It posits that a Mars - sized object (Theia) collided with Earth, and the ejected material accreted to form the Moon. This theory is supported by various lines of evidence such as the Moon's composition being similar to Earth's mantle, and the Moon's orbit and angular momentum.

Answer:

It formed from the material ejected by a giant impact between Earth & a Mars - sized object.
