What is the relationship between mare and impact crater?

Mare refers to the large, dark basaltic plains on the Moon's surface, formed by ancient volcanic activity, while impact craters are depressions created by the collision of meteoroids or asteroids with the lunar surface. Many mare regions are characterized by fewer impact craters compared to the highlands, indicating that they are younger geological features. The presence of mare suggests that volcanic activity occurred after the formation of the craters, filling in and smoothing the surface. Thus, the relationship highlights the Moon's geological history, where volcanic processes and impacts have shaped its landscape.
