Even though it's a white in colour we observe if due to phenomenal of refraction than also we thgs that its transparent but it's not a transparent material.

Answer 2

Only one side of the Moon is visible from Earth because the Moon rotates on its axis at the same rate that theMoon orbits the Earth – a situation known as synchronous rotation, or tidal locking. The Moon is directly illuminated by the Sun, and the cyclically varying viewing conditions cause the lunar phases.
