Verified Answer
Only one side of the moon is visible to us on the earth mainlydue to1....
Justification: Statement 1: The moon moves around the earth in about 27
days. It takes exactly the same time to complete one spin. As a result, only
one side of the moon is visible to us on the earth.
Statement 2: Even if the earth was not tilted, you would be able to see only
one side of the moon. The geoid shape of earth has nothing to do with our
view of the Moon. Even if the earth were to become slightly flatter or
rounder, the sight of the moon won’t change much.
Statement 3: If at all this was applicable, it should have been applicable to
all cosmic bodies, which is not true. Atmospheric refraction helps planets,
stars twinkle and doesn’t decide which side of them is visible or invisible
on earth.
