Suppose a person built a sandcastle of moon sand on the moon. What would that person find there a month later?(1 point)
Responses
The sandcastle would be much smaller because changing winds would have eroded much of the sand away.
The sandcastle would be much smaller because changing winds would have eroded much of the sand away.
The sandcastle would remain in place the same size that it was because the moon has no wind.
The sandcastle would remain in place the same size that it was because the moon has no wind.
The sandcastle would have grown larger by collecting more sand particles because moon sand is blown by wind.
The sandcastle would have grown larger by collecting more sand particles because moon sand is blown by wind.
The sandcastle would have grown larger because moon sand particles attract other moon sand particles.
The sandcastle would remain in place the same size that it was because the moon has no wind.
