Particle size is the primary basis for distinguishing among various detrital sedimentary rocks.

Question

Quizplus · Accepted Answer

Particle size is a key factor in determining the type of sedimentary rock formed from the accumulation and lithification of detrital sediment. This is because different sediment sizes have unique properties such as density, settling velocity, and transport distance, which affect how they accumulate and how they are cemented together to form a rock. Therefore, particle size is a primary characteristic used to classify and describe detrital sedimentary rocks such as sandstones, siltstones, and conglomerates.
