Why is there a far side of the Moon? Tidal forces from Earth have slowed the Moon’s rotation to the point where the same side is always facing the Earth—a phenomenon called tidal locking. The other face, most of which is never visible from the Earth, is therefore called the “far side of the Moon”.
Why does the far side of the Moon have more craters? This makes the Earth negligible as a shield for the Moon. The real reason there are more impact craters on the far side of the Moon is that the near side has a much thinner crust which has allowed volcanoes to erupt and fill in ancient large basins (or large impact craters).
Why is there a dark side of Moon? The ‘dark side’ of the Moon refers to the hemisphere of the Moon that is facing away from the Earth. In reality it is no darker than any other part of the Moon’s surface as sunlight does in fact fall equally on all sides of the Moon.
What is the difference between the far side and the dark side of the Moon? People often say “dark side” of the moon when referring to the lunar face we can’t see from Earth. This common use of the phrase is wrong — the term scientists use is the “far side.” One lunar side always faces Earth, or is tidally locked, because the moon’s rotation and orbit is closely synced-up with our planet’s.
