Sedimentary Rocks: Sedimentary rocks are formed when small pieces of material are compressed and cemented together over time to form one whole rock. Detrital sedimentary rocks are formed from rock fragments, while chemical sedimentary rocks are formed from mineral crystals that form after dissolving out of water.

Clastic Sedimentary Rocks. How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water.

Major types of clastic sedimentary rocks are (from fine to coarse constituent clasts): mudstone: clay ("blocky") and shale (splits easily) siltstone sandstone sedimentary conglomerate or breccia. Clastic sedimentary rocks are classified mainly on the basis of texture, with sensible names that refer to the size of material they contain.

Sediments (and sedimentary rocks) are classified in by origin of source material and by grain size. There are 4 sources of sediments (and sedimentary rocks): a) Cosmogenous: material that falls to the Earth surface from outer space. b) Hydrogenous: material precipitated directly seawater.Sedimentary rocks form whenever these sediments are deposited and lithified and can be classified based on the size of their grains. Gravel forms coarse rocks with grains over 2 mm in size. If the fragments are rounded, they form conglomerate, and if they are angular, they form breccia.
