Rocks that are categorized as sedimentary rocks include sandstone, breccia shale, limestone and selenite. Sedimentary rocks are classified by their grain size.
Limestone or Sandstone are two examples of sedimentary rocks. Two examples of sedimentary rocks are slate (fine silt) and chalk (shell remains of sea creatures).
Chalk and coal are examples of biochemical sedimentary rocks. Biochemical sedimentary rocks are formed from the accumulation and compression of organic remains such as shells, coral, or plant material.
Examples of organic sedimentary rocks include coal, which forms from the accumulation and compaction of plant remains, and limestone, which can contain organic debris such as shells and coral. Organic sedimentary rocks are derived from the remains of living organisms.
Rocks formed from sand, rocks, and shells are known as sedimentary rocks. Sandstones, mudstones, and limestone are common examples of sedimentary rocks that can be formed from these materials.
Some sedimentary rocks are particles and rock fragments that become cemented together. Examples of sedimentary rocks are chalk, sandstone, limestone and shale.

Sedimentary rocks are formed when sediments are compressed, compacted, and cemented together. Examples include sandstone, shale, and limestone.

Sedimentary
Sandstone, limestone, and shale are examples of sedimentary rocks. Granite, basalt, and obsidian are examples of igneous rocks.
Chalk and coal are examples of a kind of sedimentary rock called biochemical sedimentary rock. Biochemical sedimentary rocks form from the accumulation and lithification of organic remains, such as shells and plant material.
Examples of biochemical sedimentary rocks include limestone, which forms from the accumulation of shells and coral fragments, and chert, which is formed from the silica-rich remains of marine organisms. Evaporites are sedimentary rocks that form from the precipitation of minerals from evaporating water bodies, such as rock salt (halite) and gypsum, which are common examples.
