As the moon rotates around the Earth, it's location relative to the Sun changes. For example, when the Moon is “behind” the Earth (from the Sun's point of view), you see a full moon. As the Moon then passes in front of the Sun and then goes around the Earth, it goes from thin crescent to half moon to full..
Subsequently, one may also ask, why is the moon half?
Just like the Earth, half of the Moon is lit by the Sun while the other half is in darkness. The phases we see result from the angle the Moon makes with the Sun as viewed from Earth. We only see the Moon because sunlight reflects back to us from its surface.
Likewise, what blocks the moon from being full? A Lunar eclipse is when the Moon's orbit intersects with the Earth's shadow during a full moon. However, since it orbits at some angle to the Earth, it's usually 'above' or 'below' the Earth's shadow. A Lunar eclipse is when the Moon's orbit intersects with the Earth's shadow during a full moon.
Just so, why does the moon look full?
From Earth, the Moon's surface looks dark because the illuminated side is facing away from Earth. A full Moon occurs when the Moon has moved in its orbit so that Earth is “between” the Moon and the Sun. Between the new and full Moon, the amount of Moon we see grows — or waxes from its right side toward its left side.
