A footprint is left behind when an astronaut explores the moon. What would you expect to see if you looked at this same area one year later?

If you looked at the same area on the moon one year later, you would not expect to see any significant changes to the footprint left by the astronaut. The lunar surface is devoid of weathering processes like wind or rainfall, which on Earth, would gradually erase footprints. Without these natural forces, the footprint would likely remain preserved for an indefinite period of time, barring any human intervention or disturbances on the moon.
