No, the highlands having ten times more craters does not necessarily mean they are ten times older than the maria. The number of craters in an area is influenced by several factors, not just age.

Firstly, the lunar highlands and maria are exposed to different levels of meteor impacts. The highlands are located at higher elevations, making them more susceptible to meteor impacts.

Secondly, the lunar surface undergoes a process called 'gardening' where small meteor impacts churn the surface, effectively 'erasing' some craters over time. The maria, being composed of basalt, is more resistant to this process than the highlands, which are composed of anorthosite.

Lastly, the maria were formed by volcanic activity that flooded low-lying areas, covering up any pre-existing craters. This means that the maria's surface 'reset' at a later time than the highlands, so even if they were the same age, the maria would have fewer craters.

Therefore, while the highlands are indeed older than the maria, they are not necessarily ten times older. The difference in crater density is due to a combination of factors including elevation, surface composition, and geological history.

The lunar highlands have about ten times more craters in a given area than do the maria. Does this mean that the highlands are 10 times older? Explain your reasoning.
