Why does the same side of the moon always face Earth?
AThe moon does not rotate at all
BThe moon rotates much faster than it orbits
CThe moon is tidally locked, rotating once for every orbit it makes around Earth
DEarth's gravity prevents the moon from rotating
Explanation
The moon is tidally locked to Earth, meaning it rotates on its axis in exactly the same amount of time it takes to complete one orbit around Earth, so the same side always faces our planet. This synchronization developed gradually over a very long time due to gravitational interactions between Earth and the moon. As a result, the moon’s far side, sometimes inaccurately called the dark side, remained unseen by humans until spacecraft photographed it in the twentieth century.
