Which position would the Moon be in when it is a full moon?
ANo. This would be a half moon, with the half towards the Sun in light, and the half away from the Sun dark.
BNo. This would be a new moon. The entire lighted side of the Moon is facing away from the Earth, so the entire side of the Moon that we can see would be dark.
CNo. This would be a half moon, with the half towards the Sun in light, and the half away from the Sun dark.
DYes! The side of the Moon that is facing the Sun is also facing us. That entire side would be illuminated (unless the alignment was right for a lunar eclipse.)
