Explanation:
Detailed explanation-1: -The reason is that the Moon’s orbit around the Earth is tilted relative to the Earth’s orbit around the Sun.
Detailed explanation-2: -The gibbous moon appears to grow fatter each night until we see the full sunlit face of the Moon. We call this phase the full moon. It rises almost exactly as the Sun sets and sets just as the Sun rises the next day.
Detailed explanation-3: -As the moon continues in its orbit around the Earth, away from the sun, increasingly more of its sunlit surface is visible. This is why the moon sometimes appears as a crescent or half-moon. When it’s farther from the sun and visible above the horizon, it’s easier to spot during the day.
