How To Chalk sedimentary rock: 8 Strategies That Work

Sedimentary rocks are characterised by their formation from the deposition and lithification of rock material. They may be formed through physical and chemical processes, such as mechanical weathering, compaction and dissolving of rock mate...Sedimentary Rocks of the Coastal Plain. • The Coastal Plain is underlain mainly by poorly consolidated sediments consisting of mud, sand, and gravel. Chalk and coquina are common in some areas. Peat, a form of coal, is found in the Great Dismal Swamp.
