Question

Quizplus · Accepted Answer

The particle size is the primary basis for distinguishing among various detrital sedimentary rocks. Detrital sedimentary rocks are formed from the accumulation of sediment fragments that are derived from preexisting rocks through weathering and erosion. The particle size of the sediment fragments determines the name of the rock. For example, a rock composed of coarse fragments (larger than 2 mm) is called a conglomerate, while a rock composed of fine particles (smaller than 1/16 mm) is called shale.
