THE ONE THAT IS NOT BOLDED IS YOUR ANSWER
Answer: A. Earth and the Moon share many compositional characteristics
Explanation:
According to the giant impact theory, the Moon formed when an object of the size of Mars and geologically similar to Earth (which was called Theia by scientifics) crashed into the primitive Earth. With this collision, vaporized pieces of the crust of the young Earth were thrown into space. After this, the expelled particles were united by the action of gravity, creating the Moon.
This theory could explain in a certain way the reason why the Moon is predominantly composed of elements similar to those found on Earth, but lighter, making it less dense than Earth, since the material that formed it came from the crust, leaving the rocky core of the planet intact. This was verified by the samples of rocks brought from the Apollo missions, which indicate that it is composed mostly of the same components of the Earth.
