The type of sedimentary rock that forms when sediments stick together is called "clastic sedimentary rock." These rocks are created from the compaction and cementation of loose particles like sand, silt, and clay. Examples include sandstone, shale, and conglomerate.
Chalk is a common school item made from a sedimentary rock called limestone, which is mainly composed of the mineral calcite.
