This photo is showing the phases of the moon in the southern hemisphere and northern hemisphere. If you look at the moon when you're in the US (northern hemisphere) it will look like the top example. If you travel to Australia (southern hemisphere) the moon will look like the bottom example. This is because the moon will rotate along with the change in latitude Givin the viewers location. If the earth is flat, why would the moon look any different on one side of the earth than the other?
