Question

Quizplus · Accepted Answer

Breccia is a type of rock that is composed of angular fragments that have been cemented together. In an impact crater, the rocks in the surrounding area are shattered and broken by the impact, and then mixed together and compacted to form breccia. Therefore, the presence of breccia in an impact crater is significant as it indicates that the impact was large enough to break apart and fragment the surrounding rocks.
