This classification is essential to geologists as it provides critical information about the history of specific regions on Earth. These rocks change forms via the rock cycle.

Sedimentary rock is classified into two main categories: clastic and chemical. Clastic or detrital sedimentary rocks are made from pieces of bedrock, sediment, derived primarily by mechanical weathering. Clastic rocks may also include chemically weathered sediment. Clastic rocks are classified by grain shape, grain size, and sorting.

A clastic sedimentary rock. Sandstone contains sand-sized clasts, is most easily identified by its “sandpaper” feel. Sandstone usually appears as a uniform accumulation of cemented sand, which can vary in color as pink, gray, or beige. Desert environments, as well as beaches, reliably deposit sandstone.
