Explain the phases of the moon. what are the periods of rotation and revolution?
cluponka [151]

The Moon is the natural satellite of Earth. Its revolution lasts 27.322 days, while its rotation around its axis lasts 27 days. From the Earth's perspective, the Moon seems to have different phases, where it appears as fully lighted, partially lighted, or totally dark. What the Moon appears to be from the Earth depends on how the Earth, Moon, and Sun are aligned in relation to each other. If the Earth is between the Sun and the Moon, the Moon is full, with the reason being that the Sun is lighting up the side that is facing the Earth. If the Moon is between the Earth and Sun, then the Moon can not be seen, it is totally dark, and that is because the side that is facing the Earth is not lighted by the Sun at all. If the Moon is positioned sideways, not being in a straight line with the Earth and Sun, then it appears to be partially lighted, and that is the side that can be seen from Earth that is lighted by the Sun.
