Question

Quizplus · Accepted Answer

Conglomerate forms when gravel is transported for a distance, allowing for the rounding of the rocks. Sedimentary breccia, on the other hand, forms from angular fragments that have not been transported as far and have not undergone as much rounding. Therefore, option A is the best answer as it explains why sedimentary breccia is not common.
