crystal size
Sorting is the degree of uniformity of grain size of a rock
Geologists classify rocks by looking at their chemical and mineralogical composition then at the the size and shape of their component minerals then at any texture, pattern or grain that the rocks may display. They also classify them in relation to how they were formed.
Clastic rocks are grouped based on the size of the grains of sediment contained within them.
Any Size depends on where is is located and how long it sits before it breaks off
Sedimentary rocks are solid and can break into bit (rocks) of various sizes. However, if you mean what are the sizes of a "clast" in a clastic sedimentary rock then the answer is the same. A "clast" is a fragment of rock that is included in a new forming sedimentary rock - the term "clast" does not imply a size and indeed in a clastic sedimentary rock the clasts are frequently of many sizes.

Clastic Sedimentary rocks can be classified on the basis of grain size as: 1. Rudaceous 2. Arenaceous 3. Argillaceous
These are known as clastic or detrital sedimentary rocks. Depending on the size of the clasts they may be claystones (< 4 micro m), siltstones (grain size between 4 and 64 micro m) or sandstones (grain size between 64 micro m and 2 mm). If formed of angular fragments larger than 2mm in a finer grained matrix, this type of rock is known as a breccia. If the fragments are rounded, and larger than 2mm then it is a conglomerate.
Shale is composed of the smallest particles of other rocks.
Chemical sedimentary rock, those formed from precipitation or evaporation from saturated solutions.
The name of sedimentary rock is usually based on it's grain size.
The composition and strength of the cementation material.
Clastic: These rocks are composed predominantly of broken pieces of older weathered and eroded rocks Non-clastic/ Organic: A sedimentary rock composed of the remains of plants and animals.
Clastic sedimentary rocks are formed from particles of pre-existing sedimentary, metamorphic, or igneous rock that are deposited, compacted, and cemented together by natural processes.Clastic sedimentary rock is made of fragments of rocks cemented together by a mineral such as calcite or quartz.
The name of a rock is usually derived from the sediment grain size.
