Question

The discovery that the moon is similar in composition to the outer portions of the earth most supports the

theory.

synchronous

capture

impact

co-formation

Answer 1

Impact Theory

Step-by-step explanation:

"The Impact Theory has two advantages over other theories about the moon's origin. First, other theories cannot explain the differences in the composition of the earth and moon. . . If Earth and a Mars-sized object collided, their iron-rich cores most likely would have merged into the earth's core. The collision would eject dust primarily from the mantles of the two bodies. This would explain why the moon's composition is similar to the composition of Earth's mantle."

The co-formation theory is not supported by that discovery because its composition should have been the same. "Although the moon is similar in age to Earth, its composition is very different. Earth is 31% iron, with most of the iron contained in the earth's core. The moon is only 8-12% iron. This difference is hard to explain if the earth and moon formed from the same material."

Therefore, it is not the co-formation theory, it is the impact theory.

Answer 2

It most suppoet tge impact theory.

Step-by-step explanation:

The his impact theory or the big splash is one of the accepted theories of tge moon and it states that the moon or luna and explain the origin of the moon that a Mars sized object planetestimal collided with the the proto Earth and the ejecta debris joined together by gravitational force which is the moon and it's orbit the Earth. The moon have similar composition to the outer portion of the Earth.
