because of the position of your latitude on the earth, combinedwith earth's axial tilt. The points on a crescent moon define aline perpendicular to the incidence of sunlight. Viewed from theearth's equator at equinox, the Crescent always appears to be onthe bottom, or the top, because at equinox the sunlight isperpendicular to your position on the equator. However, on the sameday, viewed from the north or south pole, the crescent moon wouldappear perfectly on its side, because the earth's axis is roughlyaligned with the moon's. As your position changes across latitudes,the angle of your horizon to the incident sunlight changes. Theearth's axis is tilted 23 degrees from being perfectlyperpendicular to the sun's rays. And the moon's orbit around theearth is tilted relative to the earth's equator. This creates acomplex cycle of alignment between sunlight and your position onthe earth. Thus, the crescent of the moon will appear to tiltdepending upon where you are, what time of year it is and themoon's inclination to the earth.

The orientation of the crescent moon is determined by the relative positions of the moon, Earth, and the sun. When the moon is in its crescent phase, it is positioned in such a way that the illuminated side is facing the sun, while the bottom part appears dark because it is not receiving direct sunlight. This positioning creates the appearance of the crescent moon on the bottom instead of the side as viewed from Earth.
The orientation of the crescent moon depends on the phase of the moon in its orbit around the Earth. When the moon is waxing or waning, the crescent may appear on the bottom, side, or top of the moon, based on its position in relation to the sun and Earth. This alignment causes the lighted portion of the moon we see from Earth to create the different shapes.
