What phase would the moon be in when the earth is a gibbious seen from the moon? Please help!?

Question

This was a question in my GCSE astronomy and it has been really bugging me since the exam, i put that the moon would also be a gibbious but i really can't work it out! If anyone knows it would put my mind to rest about whther it is right or wrong! Thanks!

Answer 1

You are incorrect.

Answer 2

If the Earth appears to be Gibbous from the moon, then the moon would appear as a crescent as seen from the Earth.  

Answer 3

If the Moon is full, the Earth would be "new", and vice-versa. So if the Moon is gibbous, the Earth would be a crescent.
