What is missing from the co-accretion theory of lunar formation? an explanation accounting for the spherical shape of the moon. an explanation accounting for the presence of iron in the moon. an explanation accounting for the differences in density between the earth and moon. an explanation accounting for the origin of the material that makes up the moon.

An explanation accounting for the differences in density between the Earth and moon.

Explanation:

The co-accretion theory states that the moon and the Earth were likely formed at the same time. This theory proposes that the moon was formed from debris that came from the original nebula that formed the solar system. This theory is advantageous in many ways. For example, it would explain the heat that was necessary to create the magma ocean that we know existed on the moon. However, if the theory was right, the Earth and the moon would most likely share more characteristics, such as gravity force and density.
