Quizplus · Accepted Answer

Clastic sedimentary rocks are formed from the accumulation of small pieces of weathered rock that are transported and deposited by wind or water. They are classified by particle size, ranging from fine-grained (such as clay and siltstone) to coarse-grained (such as sandstone and conglomerate). They may also contain organic matter, such as plant debris or fossil fragments. However, they are not created by precipitation, which is a characteristic of chemical sedimentary rocks.
