The moon is not changing it's shape!
The moon's shape would change with the impact of meteor's, changing the moon's landscape.
That is the lunar cycle, or the phases.
The moon supposedly "changes shape" all the time, as the moon is constantly orbiting the Earth however the moon doesn't actually change shape, it is the amount of the sunlit side of the Earth that we see changing.

Thw moon doesn't change shape. It is an optical illusion caused by the moon's orbit around us and the way sunlight hits it. Since we can't see the "dark side" of the moon or the "far side" of the moon when it is full, it looks like the moon is changing shape.
The moon is roughly a sphere, just like the earth.During the moon's phases it may appear to be either a circle, crescent, half-circle, or other shape (called gibbous). This is caused by the shadow of the earth covering the moon by differing amounts at different times during the month, not by the moon actually changing shape.

The moon of course isn't really changing shape. It's all about the sun. The lit part of the moon you see is the part of the moon in daylight. The shadowed part is experiencing the moon's night time. These normal phases of the moon have nothing to do with earth casting a shadow on the moon.
Because the earth blocks part of the light coming from the sun so only part of the moon is alluminated, causing it to look like it is changing shape.

The Moon isn't really changing its shape. It is always round. As the Moon moves around Earth, we only see the parts of the Moon that are lit by the Sun. The Sun's light bounces, or reflects, off the Moon.
The Moon's main influence is due to the tidal forces - meaning that the Moon attracts one side of Earth (the part that is closer to the Moon) more strongly than the side that is opposite to the Moon.
