Here's why:
* Earth's Rotation: The Earth spins on its axis from west to east. This rotation makes it seem like the Sun and Moon are moving across the sky from east to west.
* Moon's Orbit: While the Moon orbits the Earth, it's still influenced by Earth's rotation. As Earth spins, we see the Moon move across the sky, rising in the east and setting in the west.
Important Note: The exact direction of the Moon's rising and setting can vary slightly depending on your location and the time of year. The Moon's path across the sky is not always perfectly aligned with east and west.
