suppose a person built a sandcastle made of moon sand on the moon. What would that person find there a month later

If a person were to build a sandcastle made of moon sand on the moon and returned a month later, they would likely find that the sandcastle remains virtually unchanged.

The moon has an extremely thin atmosphere, which means little to no air movement or weathering occurs on its surface. Without wind, rain, or erosion, the sandcastle would likely remain intact. However, there are a few factors to consider:

1. Lunar Regolith: The moon's surface is covered in a fine layer of loose, powdery soil called lunar regolith. Moon sand, which is finely ground basaltic rock, would mix with this regolith over time due to factors such as micrometeorite impacts or the astronauts' footprints, possibly altering the appearance of the sandcastle.

2. Temperature Variations: The moon experiences significant temperature variations, ranging from extremely hot during the lunar day to extremely cold during the lunar night. These extreme temperature changes could potentially affect the stability of the sandcastle, causing cracking or structural damage.

Overall, while the sandcastle may remain relatively intact, it could undergo some minor changes due to the factors mentioned above.
