Quizplus · Accepted Answer

Breccias are rocks composed of fragments of other rocks that have been cemented together. The presence of breccias among the lunar rock samples indicates that the lunar surface has been fragmented by meteorite impacts. This is because breccias are typically formed from the impact of a meteorite on the lunar surface, which shatters the rocks and creates fragments that are then cemented together to form a new rock.
