Chalk is a non-clastic lead carbonate sedimentary rock that is kind of limestone compesed that the mineral calcite. It is soft, fine-grained and also easily pulverized. Color is white-to-grayish variety of limestone rock. It is created of the shells of such minute naval organisms as foraminifera, coccoliths, and also rhabdoliths. The purest arrays contain as much as 99 percent calcium carbonate in the type of the mineral calcite. The sponge spicules, diatom and radiolarian exam (shells), detrital grains of quartz, and chert nodules (flint) uncovered in chalk contribute tiny amounts the silica come its composition. Small proportions of clay minerals, glauconite, and calcium phosphate likewise are present.

It has greater resistance come weathering and also slumping 보다 the clays through which the is normally associated, thus developing tall, steep cliffs where chalk ridges fulfill the sea.
