Final answer:
The Moon rotates on its axis in a way that one rotation coincides with one revolution around Earth, a phenomenon known as synchronous rotation, causing the same lunar face to always point towards Earth.
Step-by-step explanation:
The moon does indeed rotate on its axis, and this rotation is synchronized with its orbit around Earth in what is known as synchronous rotation. If you visualize sticking a white arrow on the Moon, pointing towards Earth, it would maintain that orientation throughout its orbit due to this synchronous rotation. The same side of the Moon always faces Earth not because it does not rotate, but precisely because it completes one rotation for every revolution it makes around Earth. This keeps the same lunar face (the side marked by our hypothetical arrow) towards us at all times. The changing appearances of the Moon night by night are caused by the varying angles of sunlight it receives, not by any rotation relative to Earth.
To demonstrate this, imagine orbiting around a friend while keeping your body facing them at all times. For each full circle you make around your friend, you must also spin around once. This is exactly what the Moon does in its relationship with Earth. The notion of a 'dark side of the Moon' is misleading because, just as with Earth, all parts of the Moon experience day and night due to its rotation.
