* Tidal Locking: The moon is tidally locked to Earth. This means it rotates at the same rate as it orbits our planet. This results in the same side of the moon always facing us.
* Different Phases: The phases of the moon we observe are caused by the changing angles of sunlight hitting the moon as it orbits Earth. A full moon occurs when the sun and moon are on opposite sides of the Earth, with the entire sunlit face of the moon facing us.
So, whether it's a full moon or a crescent, you are always looking at the same lunar hemisphere.
