Question

Which theory is supported most by the finding that the moon is similar in composition to the outer portions of Earth?

Answer 1

The theory of co formation, that is the Earth and Moon initially developed at the same time and under same evolutionary forces.

Hope this helped!

Answer 2

The correct answer is the co-formation theory.

Step-by-step explanation:

This theory states that the Earth and the Moon formed exactly at the same time and in the same place. This would imply that gravity would have caused the material in the primitive solar system, and the particles bound by gravity to form the Earth, to join together.

This way, the theory explains why the moon is similar in composition to the outer portions of Earth.
