How does an observer's latitude on Earth affect which lunar hemisphere is visible?
The specific location of the observer on Earth does not change the overall view of which hemisphere is visible.
The consistency of the hemisphere viewed from Earth is dictated by the Moon's orbital mechanics and its tidal lock with our planet, not by where an observer stands on Earth. Whether someone is situated near the North Pole or deep within the Southern Hemisphere, both individuals will perceive the same general face of the Moon—the near side. While the Moon might appear high in the sky for one observer and low on the northern horizon for another, the fundamental viewing geometry ensures the same hemisphere is presented to all points on Earth. This consistency holds true even if one travels to the Moon's South Pole and looks back toward Earth.
