Sedimentary rock chalk.
Fossils are primarily found in sedimentary rocks because these rocks form at low temperatures and pressures. Igneous rocks form at temperatures and pressures that are high enough to destroy any organic remains.
Rock salt is the name of a sedimentary rock that consists almost entirely of halite, a mineral composed of sodium chloride, NaCl. It forms where large volumes of sea water or salty lake water evaporate from an arid-climate basin -- where there is a replenishing flow of salt water and a restricted input of other water.Oolite is a type of sedimentary rock, usually limestone, made up of ooids cemented together.An ooid is a small spherical grain that forms when a particle of sand or other nucleus is coated with concentric layers of calcite or other minerals.

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. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles.

All sedimentary rocks can be identified as one of two types. They are either organic or chemical, based on the type of sediments that formed them. Answer and Explanation: 1Chert and flint occur as individual nodules or layers of nodules in limestone or dolomite; they are common in rocks of all ages (notably in the Cretaceous chalk of England). Hard and chemically resistant, the nodules become concentrated in residual soils as the surrounding carbonate rock weathers away. In places, chert forms massive beds ...
