Question

How does the age of the lunar highlands compare to the age of the lunar maria?.

Answer 1

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?

Step-by-step explanation:

How does the age of the lunar highlands compare to the age of the lunar maria? The maria are a few hundred million years younger. Which of the following objects are composed of material mostly unchanged since the formation of the solar system? Comets and asteroids.

Answer 2

the radioactive dating of highland samples showed that they are only a little older than the maria, typically 4.2 billion years rather than 3.8 billion years. If the rate of impacts had been constant throughout the Moon's history, the highlands would have had to be at least 10 times older.
