Question

Why does the moon spin round around the Earth?​

Answer 1

$\huge{\underline {\underline {\sf {❥ \: Answer }}}}$

Gravity from Earth pulls on the closest tidal bulge, trying to keep it aligned. This creates tidal friction that slows the moon's rotation. Over time, the rotation was slowed enough that the moon's orbit and rotation matched, and the same face became tidally locked, forever pointed toward Earth.
