Final answer:
The giant impact theory for the formation of the Moon is supported by computer simulations, the composition of the Moon, depletion of easily vaporized materials, and the discovery of meteorites.
Step-by-step explanation:
The evidence supporting the giant impact theory for the formation of the Moon includes:
- Computer simulations: Computer simulations show that the Moon could really have formed in this way.
- Composition: The composition of the Moon is similar to that of Earth's outer layers.
- Depletion of easily vaporized materials: The Moon is depleted of easily vaporized materials, as we would expect from the heat of an impact.
- Remains of the object: Scientists have found several meteorites that appear to be the remains of the object that caused the giant impact.
We see signatures of giant impacts on other planets. This is not evidence supporting the giant impact theory for the formation of the Moon.
