The Moon continually moves on ahead in its orbit while the Earth rotates. So 24 hours after, the Earth has rotated back around to the same place it was the night before, while the Moon has gone on ahead. assume of it like the second hand on an analog watch, it’s going around the face of the clock much faster than the minute hand, but each time the second hand goes around, the minute hand has moved, and so it takes an extra second to line back up with the minute hand. Because the Moon has moved 13 degrees or so since its last moon rise, it’s going to take another hour or so for the Earth to catch back up to the Moon’s new location, delaying the Moon's rising above your horizons by ~50 minutes each day.
