Final answer:
The Moon appears larger when it rises than when it is high up due to an optical illusion called the Moon Illusion.
Step-by-step explanation:
The Moon appears larger when it rises compared to when it is high up due to an optical illusion called the Moon Illusion.
The Moon Illusion occurs because of the way our brain perceives distance and depth cues. When the Moon is near the horizon, we have objects such as trees, buildings, or mountains to compare it to, which creates a size reference. As the Moon rises higher in the sky, it is no longer in direct comparison with these objects, making it appear smaller.
It's important to note that the apparent size of the Moon does not actually change. It is just our perception that creates the illusion.
