ONE REGION ON THE MOON IS COVERED WITH CRATERS WHILE ANOTHER IS A SMOOTH VOLCANIC PLAIN . WHICH IS OLDER . HOW DO WE KNOW ?

Question

COULD SOMEONE PLEASE HELP ME EXPLAIN THE ANSWER TO THIS QUESTION .

Answer 1

The crater one is older. During the early stages of space expansion there were more collisions. The smooth surface is due to less collisions thus not as old.
