composition
They are classified as clastic or non-clastic. Clastic sedimentary rocks are formed from rock particles of various sizes. Non-clastic rocks are formed from precipitation of minerals out of solution or by the lithification of organic matter.
None of the above. These terms describe sedimentary rocks. Granite is igneous.

Grain size is more important for determining the classification of clastic sedimentary rocks, such as sandstone or shale. Composition is more important for determining the classification of chemical sedimentary rocks, such as limestone or rock salt. Layering is more important for identifying the structure of sedimentary rocks, such as bedding in sandstone or shale.
Sedimentary rocks can be classified based on their composition, texture, and the way they were formed. Common classifications include clastic, chemical, and organic sedimentary rocks. Clastic rocks are made of fragments of other rocks, while chemical rocks form from dissolved minerals. Organic rocks are made from the remains of plants and animals. Texture can also help classify sedimentary rocks, such as fine-grained, coarse-grained, or conglomerate.
Different clastic sediments have different textures based on the size, shape, and sorting of the grains they are composed of. The composition of a clastic sedimentary rock will vary depending on the mineralogy of the grains present in the rock. Factors such as the source rock, transportation distance, and depositional environment can all contribute to the differences in texture and composition between clastic sedimentary rocks.
Clastic sedimentary 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.
They are all Sedimentary
The basic division of sedimentary rocks is into clastic and chemical rocks. Clastic rocks are formed when grains form a sediment and are then cemented together, as happens with sandstone or shale. Chemical rocks form when solid precipitates out of solution, for instance when calcium carbonate is formed from sea water to give chalk.
Shale, sandstone, and conglomerate are examples of clastic sedimentary rock.
Shale is clastic sedimentary rock.
