No atmosphere
So no rain or wind to remove them
A moonquake might lessen them
There were recent amazing pictures released to the press of the surface of the moon which showed many of the objects left on the moon including footprints! So you know the footprints last over 40 years because it has been that long since Neil Armstrong made history with the first footprints on the moon. There is no atmosphere on the moon therefore no rain, wind or water flow so the only thing that will destroy the footprints is space debri of either man made materials or rocks such as a meteor storm. Scientist from different nationsintentionally crash objects into the moon for various studies.
To provide an accurate answer, I would need more context about the specific footprints you're referring to. Footprints can be made by various beings, such as humans, animals, or even prehistoric creatures. If you have a particular location or type of footprint in mind, please share more details for a more precise response.
We have not yet found any evidence of life on Mars, let alone footprints.
We can't be absolutely sure how long a footprint will last on the moon since it might or might not be struck by a meteoroid or other cosmic debris, but potentially it could last for billions of years. It is also possible (although I am not expecting it) that the moon will someday be colonized by people, who will then disturb the existing footprints. But then again, they might want to preserve them as monuments.
It is made out of sand which is silicone dioxide also called quartz.
They are sandals made in Germany for almost all. The Footprints line of shoes was made in Portugal.
The footprints were made by a dog.
Well its when there feet get wet or when there paws are sweating is when they can track footprints. Like if you dog steps in made then you will see dog prints.
Neil Armstrong made footprints.
The volcano that made the Laetoli footprints possible is the nearby Sadiman volcano, which erupted about 3.6 million years ago and covered the site with a layer of ash. This ash then hardened, preserving the footprints made by early hominins as they walked across the area.
Dinosaur footprints are the original soil or sand that the footprint was made in, which has been buried and then turned into rock by great pressure. In a nutshell, yes.
Some clocks are hundreds of years old (and still fully functional); others were only made last week.
